January 14, 2010 – Site Maintenance
Sorry for the lack of recent updates, I have been struggling with the (apparently well-known) problem of WordPress 2.9 requiring MySQL 5, but the site having been set up with MySQL 4. This might not otherwise be a problem if my host didn’t include a 2MB maximum on MySQL importing, roughly 30 times smaller than I needed. Only today did I manage to overcome, and WordPress is now MySQL 5 upgraded to the latest version.
In the interim, I have received some disk sets, been making boot disks for people, and procured a new CatWeasel 4+ (which seems to be working just fine).
I hope to get things moving again soon …
January 15, 2010 – CatWeasel Utilities Updated
Tim Mann has updated his CatWeasel read/write utilities to v4.4. Changes are:
- The Linux binaries included in this distribution are compiled on a 32-bit Ubuntu 8.04.3 LTS system. The MS-DOS binaries are still compiled with a version of djgpp from the year 2000, under djgpp. The MS-DOS binaries are untested at the time of this release.
- Updated to the current Catweasel MK4 firmware from Individual Computers, moving from pre29.cw4 to rel2f2.cw4. Changed catweasl.c slightly to work with the new firmware — the write pulse width now must be set.
- Fixed cw2dmk bug where the total sectors read in each encoding counted all retries, not just the last one.
- Added -r option to cw2dmk and dmk2cw to reverse the sides. This is mostly to help split/join disks that have a separate one-sided image on each side but were written with a double-sided drive (that is, they are not flippy) to/from two separate DMK images.
- Fixed an incompatibility with newer versions of libpci that had prevented recompiled Linux binaries from recognizing a PCI Catweasel.
- Added a dmk2cw option to use only a prefix of the track in the DMK file.
- Changed the way dmk2cw generates fill data when the DMK track is shorter than needed to fill the disk. Added an option to select some alternative fill methods.
- Some small fixes and cleanups, mostly in documentation and messages.
January 26, 2010 – TRS80GP Emulator Updated
George Phillips has updated his TRS80GP emulator to v1.5.1 to correct a bug. It can be downloaded from the emulator page or from George’s site. His explanation for the change, as posted on his site is:
The pause/break key wasn’t activating the TRS-80 BREAK key on some computers. The problem was a little more involved than I realized. As Wikipedia hints, Pause/Break is a little unusual. On some systems, especially laptops, Windows will report the key is down and then immediately say it is up again – well before the key is actually released. I’m guessing this is a consequence of they key not actually reporting the up state at the hardware level. Windows is faking it to help programs operate.
This would be fine except that the emulated TRS-80 takes 2 or 3 frames to recognize the key. I presume that’s to avoid keyboard bounce. Now what I do is artificially sustain the down time of any key which takes care of Pause/Break and should help with the emulator’s propensity to miss keys. It wasn’t so bad, but I did notice dropped letters when I was typing things into the emulator.
I even documented the keyboard mapping while I was at it.

February 17, 2010 – For Those with a 4P
As far as we know, the Model 4P had only 2 BOOT ROM’s, v1(15) and v1(16), the former being dated October 11, 1983 and the latter being released 7 days later.
Although technically the v1(15) ROM would have been in every Model 4P released before October 18, 1983, the 7 day window leads us to believe that it would have applied only to very very very early models. However, there is no known dump of the v1(15) ROM.
If you have a Model 4P and are interested in helping, turn it on and hold down the “V” key. After a few seconds a message which reads “Boot ROM Version is ___”. If you have a 4P where it is 1(15), and are willing to dump the ROM (instructions will be provided), please send me an email.
February 24, 2010 – Update to TRS32 Emulator
Matthew Reed has updated his wonderful TRS32 Emulator to v1.23. This update includes:
- Model 4P emulation mode
- Improved consistency of directory handling with drag and drop
March 3, 2010 – New DSK/DMK Import/Export Utility
Matthew Reed has released his command line DSK/DMK image utility pair TRSREAD and TRSWRITE. They perform many of the same functions as TRSTools, only on the command line.
TRSREAD is a command line Windows program that can extract files from a TRS-80 virtual disk, with optional flags for including “S”ystem files and “I”nvisible files. You can use wildcards or a list of files you want to extract.
TRSWRITE is a command line Windows program that copies files onto TRS-80 virtual disk files.

April 19, 2010 – Free Truckload of TRS-80’s but Local Pickup by 4/22 ONLY
UPDATE 2: All Gone.
UPDATE: There is already one taker, but it is currently unknown if this is a done deal, and two other’s on the waiting list.
Original Post:A long time site visitor would would like to get rid of his entire collection of TRS-80 computers, software, manuals, accessories, etc. This includes somewhere between 10 and 20 TRS-80s…everything from Model I’s, Model III’s, Model IV’s, 4Ps, Coco’s, etc.
There is enough stuff to fill the entire back of a pickup truck or suburban.
It will all be free, but pickup only in Phoenix, AZ.
It needs to be picked up by Thursday 4/22 or it will probably go in the dump; and is all or nothing.
First come first served; I will put you in direct contact in the order I am emailed.

June 24, 2010 – DISK REQUESTS ARE OFFLINE
UPDATE 2: I am limping along right now on a drive which may or may not be good. It is entirely possible that it is good, but the disk set remains bad. I will hold off restoring the link to the Disk Requests until the new drives come in.
UPDATE 1: I have now spent a fairly decent amount of money to acquire 4 floppy drives (will they work, who knows) on eBay.
A particularly dirty set of disks sent to me for conversion has knocked my disk drive out; and my attempts to use spares are proving futile. I will not be able to convert disks or make DOS disks until this has been resolved.
June 28, 2010 – Vintage Computer Festival Southwest
A. G. (Gil) Carrick, the Director of the Museum of Information Technology at Arlington, has asked that I post the following about the upcoming Vintage Computer Festival Southwest …
The 1st annual Vintage Computer Festival Southwest will be held August 7th and 8th, in the Rio Grande Ballroom, in the E.H. Hereford University Center, University of Texas Arlington. The event is sponsored by the Museum of Information Technology at Arlington, the UTA College of Engineering, the UTA Office of Information Technology and Vintage Tech. The VCF is an international event that celebrates the history of computing. There have been VCFs at several locations since 1997
The mission of the VCF is to promote the preservation of early computers by allowing people to experience the technologies, people and stories that embody the remarkable tale of the computer revolution. Southern US companies played a large role in the early days of the computer industry and the VCF Southwest hopes to focus on their contributions.
VCF is not a swap meet, but you will have a chance to buy things or even come home with prizes. There will be speakers and videos each morning, exhibits each afternoon, and special events throughout the weekend. More details about the schedule will be available soon.
The VCF is held indoors, rain or shine. Admission is $10 for one day, $15 for both days, and free for ages 17 and younger. Parking is free. Hours are 9 A.M. – 5 P.M. on both Saturday and Sunday.
July 8, 2010 – Orchestra/90-PC Updated
Jon Bokelman, creator of the ORCH-80/85/90, has updated his Orchestra/90-PC program to v2.0.
For those who don’t know, Orchestra-90/PC is a simple, no-frills program that plays original Orchestra-80/85/90 and Piano-85/90 ASCII files on a PC using a sound card. It is launched from the command line.
The main change is that a new command line switch, “-w filename” has been added to output the ORC file to a WAV file of filename filename.
A readme file is included in the archive.

Miguel Dutra has released v0.6 of his Command Line version of his Virtual Disk Manager utility for Windows. This is a small utility which allows you to access virtual TRS-80 disks at a file level, as if they were normal PC disks.
It appears that this utility can read all known TRS-80 DOS’s except for (1) CPM and (2) anything made by Percom.
The new version brings:
- Write-capable
- Fixed a bug which caused it to read an invalid sector when the file size exceeded one disk track.
July 31, 2010 – Need Model 4 Power Supply
Vernon Hester, who wrote MultiDOS and a few other programs, had been updating his programs and DOSes. Vernon was in the process of updating a few more items, and getting together a real copy of the last Model I single density MultiDOS, when his Model 4 power supply went out. Does anyone out there have a source for a Model 4 power supply for Vernon? Thanks

September 10, 2010 – New Downloads thanks to Vernon B Hester
Vernon B. Hester, author of MultiDOS and other wonderful programs, has provided some additional copies of his DOS’s:

- MultiDOS v4.01 for Model I
- MultiDOS v4.01 for Model III
- MultiDOS v5.11 for Model 4
ESOTERIC is a Model 4 version of MULTIDOS with two differences: Video (Esoteric is 80×24 vs. MultiDOS which is either 80×24 or 64×16) and ESOTERIC is mapped significantly different than Model 4 MULTIDOS. The mapping of the Model 4 is very similar to the Model I, Model III, and MAX-80 version of MULTIDOS, while ESOTERIC’s mapping difference was desired to keep the DOS in contiguous memory (0000H through 1AFFH) allowing one to ORG applications at 1B00H.

In sorting thru the lastest software shipment I came across a little program which claims to identify whether your Model I ROM was v1.0, 1.1, 1.2, 1.3, or other. The ROMs out in the wild are either v1.0, v1.2, or v1.3. Does anyone have a Model I system with v1.1?? The program is as follows:
10 REM PROGRAM TO FIND VERSION OF MODEL I ROM 20 CLS 30 FOR I=11264 TO 12287:V=PEEK(I):S=S+V:NEXT I: X=S/16 40 A=(X-FIX(X))*16:Y=FIX(X)/16:B=(Y-FIX(Y))*256 50 V=(A+B) 60 IF V=176 PRINT"ROM 1.0": GOTO 100 70 IF V=142 PRINT"ROM 1.1": GOTO 100 80 IF V=10 PRINT"ROM 1.2": GOTO 100 90 IF V=162 PRINT"ROM 1.3" ELSE PRINT"VERSION OF ROM UNKNOWN" 100 END

September 30, 2010 – Updates to Matthew Reed’s DMK Utilities
Matthew Reed has released:
- v1.04 of Windows GUI DSK/DMK image utility TRSTOOLS; and
- v4.27 of his TRSREAD and TRSWRITE command line utilities for TRS-80 virtual disks.
The changelog for both includes:
- Improved viewing of MULTIDOS BASIC programs; and
- Improved recognition of DOSPLUS and NEWDOS/80 disks.
October 12, 2010 – MultiDOS Update
The copies of MultiDOS for the Model I have been reviewed by Vernon Hester who has explained some of the images, and provided information necessary to restore others to verified true copies. If you downloaded the Model I MultiDOS images in the past, you might want to re-download them.
Interesting Notes:
- MultiDOS for the Model I came in three formats: Single-Density, Double-Density (similar to DOSPLUS and LDOS), and “P”-Density (similar to NEWDOS/80 Double-Density which has track 0 as single density, and all other tracks as double density).
- MultiDOS v1.5SK (at least my copy) was really just a special kernel made for Computer Shack so they could distribute SuperDirectory (since a disk cataloging program needs to be able to read as many DOS’s as possible; which is MultiDOS’s specialty). That is why the system files are all called CSx/sys (Computer Shack) and the version is SK (Special Kernel)! It has only 16 Library commands: Auto, Boot, Clear, Clock, Cls, Config, Date, Dir, Forms, Kill, Lib, List, Print, Skip, Time, Verify.
- MultiDOS II (at least my copy) was really just a distribution diskette for ZEUS. This DOS will boot on a Model I and a Model III.
While most of my MultiDOS images were modified to some level, the copies of v1.4S, 1.4D, 1.6D, 1.6S, 1.7D, and 1.7P are all now “correct.” Vernon *may* be providing “correct” copies of v1.0 and v1.5 in the future. Of course, Vernon has provided 2004 and 2005 updates to MultiDOS, but for those who want the classic versions, there you go.
October 12, 2010 – Possibly Found v1.0 and v1.1 ROMs
A site visitor has indicated that he believes he has a Model I which has the v1.0 and the v1.1 ROMs and intends to either dump them to cassette or read them in an EPROM reader. Of course, if anyone finds they have v1.0 or v1.1 ROMs, please let me know. ROMs can be dumped to disk as follows:
10 PC=0 : IR=0 20 OPEN "O",1,"NEWROM/ROM:0" 30 FOR X = 0 TO &H2FFF 40 PRINT #1,CHR$(PEEK(X)); : IR=IR+1 50 IF IR = 614 THEN IR = 0: PC=PC+5: PRINT PC"% ..."; 60 NEXT X 70 PRINT "DONE!":PRINT 80 CLOSE
It takes about 1/2 hour to run (which is why I coded in 5% increment status updates)
October 13, 2010 – Update to TRS32 Emulator
Click to Enlarge
Matthew Reed has updated his wonderful TRS32 Emulator to v1.25. This update includes:
- BUG FIX: There was a a one bit error in the emulated interrupt status ports which caused one NEWDOS/80 boot disk to kept generating “Device not available” errors instead of displaying a directory.
- BUG FIX: There was a Model III boot disk which was being identified as Model 4 by the “Autostart” feature. Although the disk still worked (it just ran in Model III mode), recognition of this unusual boot sector was added to the autostart routine.
- NEW FEATURE: Hovering the mouse cursor over the floppy drive indicator light in the status bar will display the current drive status and position; making it easier to determine if a boot disk is loading or just cycling endlessly.
The updated emulator can be downloaded from the TRS-80.com emulator page.
October 15, 2010 – Model I ROM v1.0 Found; v1.1 Still Missing
Click to Enlarge
v1.0 of the Model I ROM has been dumped. Sadly, while the individual thought he had v1.1 too, it turned out to be v1.2. Anyone with v1.1, please give a shout out. Thanks!
Update: It was found in June of 2020!
October 16, 2010 – More Model I MultiDOS Images
Vernon Hester has kindly provided Model I MultiDOS versions 1.0, 1.5S, 1.5D, and 1.5P.
October 26, 2010 – Explanation as to Model I ROM Versions
In hopes of answering all of the questions which have arisen from the realization that there are 4 versions of the Model I ROM and we (at the time) had only 1 of them, Matthew Reed [Hotlink Deleted], author of the amazing TRS32 emulator, has posted a brief explanation of the ROM versions.
October 27, 2010 – Model I ROM v1.1 Found
v1.1 of the Model I ROM has been dumped by John Benson. Thank you John!

December 9, 2010 – Program to Dump ROM to Cassette
Kurt Baumgardner wrote a short BASIC program to allow those with Model I’s to dump their ROM’s to cassette if that is their only option. Kurt advises that it needs 16K of RAM and takes a little less than 3 and a half minutes to run. He did not test it on a Model III but assumes, at the very least, that the ROM line would need to be changed from ROM=12 to ROM=14
10 CLS : PRINT " ROM DUMP TO TAPE" : PRINT 20 FOR T = 32512 TO 32537 : READ B : POKE T,B : NEXT T 30 POKE 16526, 0 : POKE 16527, 127 40 ROM = 12 ' 12K OF ROM ... CHANGE AS NEEDED 50 POKE 32523, ROM * 4 60 INPUT "READY CASSETTE"; T 70 T = USR (0) 100 DATA 175, 205, 18, 2, 205, 135, 2, 33, 0, 0 110 DATA 14, 48, 126, 205, 100, 2, 35, 16 ,249 120 DATA 13, 32, 246, 205, 248, 1, 201

Theresa Welsh let me know that there is now an eBook version of the TRS-80 related book “Priming the Pump: How TRS-80 Enthusiasts Sparked the PC Revolution”. The announcement is as follows:
Priming the Pump: How TRS-80 Enthusiasts Sparked the PC Revolution, is in its second printing and we have just released it in two eBook formats: for the Kindle (sold by amazon.com) and for the Nook (sold by Barnes & Noble).

The price for the ebook version is only $9.95.
Here are the links to where the ebook versions can be purchased:
Kindle version: http://www.amazon.com/dp/B004P8JNIS

May 4, 2011 – TRS-80 Model III and 4 for FREE (Local Pickup Only)
A site visitor has a Model III and a Model 4 available (+ dust covers) for free for local pickup only in Natick, Massachusetts. When last used in July of 2009, the Model III worked perfectly, and the Model 4 worked other than drive :1 (although the individual did not attempt to determine why).
To avoid the standard problem of people emailing the individual to ask if they will ship, you are asked to contact me. I will pass on offers to pick up the computers. First come first served.

May 8, 2011 – WordPress Trouble and New Page
Now that I moved the NEWDOS/80 Manual to be on a non-Wordpress page (like I had to do with the individual magazine pages), I can add pages again. I guess I am hitting some kind of memory/size limit on WordPress.
Anyway, I thought it would be useful to put all the “TRS-80 For Free” listings on their own page, and so I did.
Also, David Cooper has been kind enough to convert the Disk Request Page to be usable for systems without a mailto: configuration. Thanks David!

June 1, 2011 – Updates to Matthew Reed’s DMK Utilities
For those of you tired of seeing endless numbers of scans, here is some big news.
As enthusiasts may know, Matthew Reed has been working on patching LDOS so that it can accept dates after 2012. A description of the problem and the technical solutions can be found at:
http://www.trs-80.org/ldos-and-ls-dos-2012-and-beyond/ for Part 1 – LDOS and LS-DOS: 2012 and Beyond
http://www.trs-80.org/ldos-and-ls-dos-2012-and-beyond-technical-information/ for Part 2 – LDOS and LS-DOS: 2012 and Beyond – Technical Info
http://www.trs-80.org/ldos-and-ls-dos-2012-and-beyond-a-solution/ for Part 3 – LDOS and LS-DOS: 2012 and Beyond – A Solution
Matthew has just released the new version of TRSTools, which includes the feature to automatically patch LS-DOS/LDOS boot disks to extend their file dating capability to 2079. No separate date conversion step is necessary. Just load the (non-write-protected) LDOS 5.3.1 or LS-DOS 6.3.1 boot disk into TRSTools and allow it to patch the disk when it asks. The LDOS patches don’t take up any additional disk space and didn’t require getting rid of any file passwords. The new TRSTOOLS also [1] improves recognition of all three MULTIDOS date formats, [2] fixes a problem with reading from a heavily fragmented Model III TRSDOS dsk, and [3] added an option in the file viewer to switch to a hexadecimal view.
Matthew has also released updated versions of TRSREAD and TRSWRITE that can handle the new extended dating format.
June 2, 2011 – Any C++ Programmers Out There?
If you are good at C++ and good at modifying someone else’s source code and knowledgable about the Catweasel, please read on …
… as many of you know, TRS-80 disks were never meant to hold data for 30+ years, and one of the things I do for people is read their disks into DMK images. Much of the time, people are trying to get their old documents and records off the disks, so getting the best possible read off the disks can mean the difference between a corrupt file or a good one.
To do the disk reading I have a dedicated system set up with a Catweasel, a floppy drive, DOS boot, and Tim Mann’s wonderful Catweasel utilities.
As any of you who have a Catweasel may know, Tim’s utilities allow for a command line option to give a specific number of retries for any track which reads with errors BUT it outputs the track as read on the LAST read rather than the track as read on the BEST read. You could have 19 reads of “9 good sectors, 1 bad sector” but if the 20th retry is “6 good sectors, 4 bad sectors” that is what you get, and 3 otherwise good sectors are lost (you can restart the process again, but it is all going to be a roulette game). Those sectors being good could easily mean the difference between a good file and a corrupted one.
The reason for this, however (and as Tim has previously told me), is that the Catweasel works only on a Track level, which is the rub.
I am wondering if anyone out there has the C++ know how to modify Tim’s CW2DMK.c program so that when a track is read (as currently written in the program), an array is populated with the actual sectors (which I guess might be one entry for any DMK header, and the remaining array equal to the track length divided by the sector size; but what do I know), and then if a successive retry produces a good sector where there was previously a bad one, the (bad) sector in the array is replaced with the newly successfully read one; and once the retry count is done, the array is assembled into a track; at which point the track is written out (as currently written in the program).
Tim has been busy with other projects (he has been well aware of the request for quite some time), and the track vs. sector nature of the Catweasel probably makes this a project he does not wish to tackle, but a recent set of disks where the person was desperate for their data has just triggered me to see if anyone out there can do it. Modifying the source code appears, on my quick read, to be permitted under the license under which it was issued, provided certain obligations are met.
However, it is Tim’s project, Tim’s source, and whether this is actually made public should be entirely up to Tim in my book. Certainly anyone who writes in the functionality is encouraged to send it to Tim; perhaps he will integrate it.
Links:
- http://www.tim-mann.org/catweasel.html – Tim’s Catweasel Page (with links to v4.4; source code is included)
- The DMK format is explained at the bottom.
- The FREE MSDOS C++ compiler which is used to compile the Catweasel utilities is the DJGPP Compiler (http://www.delorie.com/djgpp/). Tim’s makefile is makefile.dj for that reason.

July 10, 2011 – Tutorials for Linux
Larry Kraemer has developed some step-by-step tutorials on how to run David Keil’s DOS Emulators and Tim Mann’s XTRS Emulator under Debian and Ubuntu. As of December 2019 it is almost all incorrect so the link has been removed.
July 13, 2011 – Emulator Updates
George Phillips has updated his GP2000 TRS-80 Model I/III/4 Emulator to v1.8. Changes include:
- Works on displays whos width is not a multiple of 4.
- Recording in Flash video format (.flv).
- Supports Model 4 with hi-res graphics adapter.
- Debugger improved.
- Z-80 profiling has legend and branch taken percentages.
- HALT instruction now emulated properly.
- Model I double-wide video.
- Added “-time emulation” option to show CPU emulation time.
Stephen James Hurd and Ken Pettit have updated their Model 100 emulator, Virtual T, to v1.5. The update can be downloaded from the emulator page.
David Keil’s site appears to have gone down. Since that site was the only source of David’s emulators (and also because David’s emulators were entirely incompatible with Windows XP or LCD monitors since Dave chose to use direct hardware writes for screen updates) references to David’s emulators on the emulator page have been removed.

February 8, 2012 – New Z80 Assembler for a PC
Matthew Reed, author of the amazing TRS32 emulator as well as the DSK/DMK Utility TRSTOOLS, has just released Z80Asm, a new Z80 macro assembler for creating TRS-80 CMD files.
Z80ASM assembles TRS-80 assembly language programs and creates /CMD files that will run on a real or emulated TRS-80, but it runs on the command line of your Windows PC. The assembler is a shareware Windows-based command line utility designed to make it easier to develop TRS-80 software on a Windows computer.
The unregistered version differs from the registered version in that the unregistered version:
- Generates only CMD files, not HEX, core image, or COM files
- Does not generate an equate listing
- Does not allow reading from or writing to TRS-80 virtual disk files
February 9, 2012 – New MISC UTILITIES Page

It uses a piece of generic hardware called a Duinomite Mini out of Bulgaria. Ken reports that it was a proof of concept that actually worked very well (the only thing that needed work was the floppy emulation).
Anyone wanting to reach out to Ken can email him at kensegler@gmail.com.
May 13, 2012 – Cleaning Up The Site
The introduction of PC Operating Systems without direct hardware access (2000, XP, Visa, Windows 7) and without 16 Bit Access (Windows 7/64), and the removal of ISA ports and 5.25″ Disk Drive support in the BIOS of current PC’s, has left many pages on the site drastically out of date. I have been working to clean up and consolidate pages, move/remove software which is too old to run, and generally get rid of information which is no longer relevant or viable. The Disk and Cassette pages (both conversion and manipulation utilities) have been rewritten, the Emulator page has been cleaned up, and the Scott Adams adventure page updated with new stuff. I have no the slightest clue how to make the Hardware Mods or the Zaps/Mods/Pokes/Tricks more user friendly, but perhaps inspiration will hit.
The revised pages will have a Model 4P on top (a system which this web site ‘supports’) instead of the Model 100 (a system which this web site does not ‘support’). Please report 404 errors on files, as those have been restructured and cleaned up as well.
May 16, 2012 – Still Cleaning
I am continuing to try to clean up the site. Currently there are 419 news posts (well, now 420) and 129 pages comprising the site and I am slowly dropping needless pages (or combining them with others). Please let me know of any 404’s or missing images. Thanks.
May 21, 2012 – Still Cleaning / New Pages
As I continue cleaning (pages with a Model 4P on the top instead of a Model 100 have been completed) I have come across a few pages I had in development and never hooked up. While the MultiDOS pages (noted on the right menu) are still in development and will not go live until Vernon Hester says they can, I have added a pagefor my attempt to classify the TRS-80 ROMS.
May 22, 2012 – Searchable Radio Shack Catalog Number List
A Searchable Catalog Number page has been added. It differs somewhat from the other catalog lists out there in that all but 13 items have the actual catalog entry available. If you know of any items which are missing regarding the Model I/III/4/4P, please let me know the item, the catalog it appears in, and the page number.

May 30, 2012 – Search Options
The CATALOG NUMBER SEARCH PAGE and SOFTWARE ARCHIVE SEARCH PAGE continue to be updated, as do their underlying databases. In order to facilitate adding catalog numbers to the software archive, three new changes have been introduced … 1) Sorting can be done by catalog number (not a particularly useful feature) in the Software search and 2) You can search for all Radio Shack or Tandy software by entering TRS (capitals only) into the Author field of the software search (as some items were copyright Radio Shack and some Tandy; and neither search produced complete results independently), and 3) The catalog search page can limit results to Model I/III/4 only.
What strikes me is how many Radio Shack software products have not been archived. Had no idea it was that many.

June 24, 2012 – TRS-80 Floppy Disk Drive Replacement
Scott Goldman is busy trying to get a Lotharek SD Floppy Emulator working in his newly acquired Model 4. The SD Floppy Emulator seems to be a replacement for an actual floppy drive within a TRS-80. It supports JV1, JV3, and DMK images which are stored on a removable SD Card and selected by scrolling through the disk images using the push buttons located on the bottom right of the board.

June 25, 2012 – TRS-80 CP/M Page Added
Since I am trying to sort through the unsorted TRS-80 CP/M files I have, I have created a TRS-80 CP/M page.
The project is somewhat of a bear because the ONLY way I have figured out how to get files ONTO a CP/M virtual disk, is to utilize a program called NWD80CPM written by Blandford Computers for the Genie III running under an emulated CP/M disk; and for some reason they require you to enter the CP/M Destination Disk, the NEWDOS/80 Source Disk, the NEWDOS/80 Filename (NO WILDCARDS, even though they are supported under CP/M), A yes/no as to whether you want to add line feeds to carriage returns, and then a yes/no that confirms that the disks are mounted … FOR EACH FILE. Should you run out of disk space at any point in this process, you must start over, as not exiting the program gracefully leaves a corrupted directory. It also will not process filenames which are illegal under NEWDOS/80 even if they are legal in CP/M. It will also error out if you attempt to copy a zero length file.
June 26, 2012 – TRS-80 CP/M Added to the Archive Search Page
The TRS-80 Software Archive Search page has been updated to include sorted CP/M programs. Only CP/M programs which run on a Model 4 system are included.
June 29, 2012 – Catalog Search Page Updated
Thanks to a combination of Adobe Acrobat’s built-in OCR (for what it is), QuickBasic/64 (how did I not know you existed?!?!), and Textpad, I was able to have the computer determine whether RSC-17B had any catalog entries that were not yet added to the TRS-80 Catalog Search Page. The answer was a resounding yes, and the TRS-80 Catalog Search Page is now up to 2250 entries, all but 35 of which have the actual catalog entry present as an image.
These efforts have also shown me that Radio Shack re-used catalog numbers. So far, I have found 3 instances:
25-1151
Where In The World is Carmen Sandiego (PC)
Dr. Graph (1000)
26-1225
Active Junction Box
Q & A 3.0 (PC)
26-1601
Scripsit Pro (4)
Home Recipe Program (1)
I am not sure I will continue adding Radio Shack entries, as we have long exhausted the Model I/III/4 entries, and I am not so interested in what the 6000 might have in store for the Xenix operating system. If I had a better scan of a Med Systems catalog I would do that as well, but I do not. Off to other projects I guess.
June 29, 2012 – Catalog Search Page Updated Again
The TRS-80 Catalog Search Page has been updated again, but do not worry, there is no end in sight for what the Tandy 5000MC has to offer. Almost 200 more entries (complete with images) has been made, bringing the catalog database to 2,429 entries, all but 35 of which have the actual catalog entry present as an image.
July 2, 2012 – Catalog Search Page Updated Again
While I continue to wait for my next project, the TRS-80 Catalog Search Page has been updated again. Almost 50 more entries (complete with images) has been made, bringing the catalog database to 2,482 entries, all but 32 of which have the actual catalog entry present as an image. It is getting tougher to find new items in the sea of catalogs.
I also sorted through the hardware manuals to make sure that everything was presented, and horrendous copies of otherwise existing manuals were removed. Covers will be replaced shortly.
July 3, 2012 – Book Page and Catalog Search Page Updated Again
While I continue to wait for my next project, the TRS-80 Catalog Search Page has been updated again. 89 more entries (complete with images) has been made, bringing the catalog database to 2,571 entries, all but 32 of which have the actual catalog entry present as an image.
I also cleaned up the Book page to include all books present, and to add cover shots. Cover shots are being regenerated using a PDF to JPG program (which also names the JPG based on the TOSEC file, so updating all covers can be done with a macro).
July 4, 2012 – Catalog Search Page Updated Again
While I am still standing by in hopes of the release of something which will allow me to continue another project, I continue to work on the TRS-80 Catalog Search Page. The page has been updated again with 190ish new entries (complete with images), bringing the catalog database to 2,757 entries, all but 5(!!!!!!!!!!) of which have the actual catalog entry present as an image.
July 6, 2012 – Catalog Search Page Updated Again
The TRS-80 Catalog Search Page. The page has been updated again with 230 new entries (complete with images), bringing the catalog database to 2,987 entries, all but 5 of which have the actual catalog entry present as an image. I honestly don’t know about those 5 … I am currently doing a final sweep of RSC-2 through RSC-19 in one big OCR’d PDF looking for missing numbers, and they are not in any of those catalogs.
July 7, 2012 – Catalog Search Page Info
I have received a few questions about the TRS-80 Catalog Search Page so let me try to answer a few.
- I have not tracked which RSC any given item listing came from. It may have been based on nothing more than it being the cleanest copy, or the PDF’s OCR showing one issue over another.
- For those interested in seeing the whole catalog, simpy search for a dash as the catalog number; its the one common denominator. However, if you do so, the graphics will require serious scrolling as lightbox seems to place picture in the center of the page; and the page will be 3000 lines long.
- I am not done, but I am almost done. All of the remaining items I know I am missing are in the 90-xxxx block.
- Anyone and everyone is welcome to contribute. If anyone would like to provide JPG’s of catalog entries, feel free.
July 9, 2012 – Catalog Search Page Updated Again
The TRS-80 Catalog Search Page has been updated for what is probably the last time. The catalog is now up to 3188 items, all but 5 with images. 736 images were re-processed.
The search page itself has been updated to advise that simply pressing SEARCH will bring up all results.

July 30, 2012 – Control Data Diskettes
Click to Enlarge
A very brave David Cooper is going to attempt to read Control Data diskettes. My experience over the decade+ of reading disks is that any data stored on a Control Data disk is irretrievable because the diskettes immediately shred their magnetic oxide coating all over the disk head and mechanism upon first access; destroying the disk and destroying (or resulting in a need for a very good cleaning) the disk drive. Our thoughts should be with David and his soon-to-be-ex floppy drive.
July 31, 2012 – David Cooper vs. Control Data Diskettes Part II
Click to Enlarge
David Cooper is having some luck with the Control Data diskettes. It seems that these Control Data disks treat a disk drive exactly the same way that an moldy diskette treats a disk drive; when you insert them they sound like sandpaper, and the bumps are enough to get caught on the drive head, flake a little, which then turns the drive head into a rough surface which cuts more out of the disk, which flakes more, which coats the head more, etc. With the Control Data disks, though, it also seems that they had some serious issues with adhesion, and this process wears deep grooves in the disk almost immediately. With this, the disks seem to be only readable once (or at least, you cannot re-read and then re-re-read them), so it is basically a handful to read them. David is going to look into modifying CW2DMK to cache good read sectors (and then write out the best compiled sectors, rather than simply the random number of sectors that happened to read when the retry counter ran out) and to allow for starting at a specific track, both of which are somewhat necessary to get through many bad disks, but neither of which are not currently supported.
How is David reading them? He tries to pre-clean the diskette with alcohol to get as much of whatever is on these disks off as possible. Mind you, there are no visible stains on these disks to give a hint that this would need to be done. If one can get enough of the mystery goo off the disks, they won’t flake and they won’t clog the head, carving chasms into the diskette. Unfortunately, the disks also aren’t very good at retaining data, so once the errors creep up, he cleans the head again and tries again. This process will be smoother when/if CW2DMK is modified.
David may put together a video on how to clean a diskette; but his general theory is to apply rubbing alcohol to the exposed area, and then manually turn the disk by hand by grabbing inside the ring and applying gentle pressure to the diskette jacket to use the cloth inside to spread and clean the disk. Of course, if this brand of disks was not bad enough, the center reinforcement ring pops off at the slightest bend, so be prepared for that to happen too.
To clean his drive, he uses an actual 5-1/4 inch disk cleaner and uses the “clean” feature of imd.exe to step the heads back and forth in a good motion of disk cleaning.
I have never been successful cleaning a disk, and to clean my heads after a good coating, I just use que-tips and rubbing alcohol. I keep the screws out of the drive, and any time I start getting progressive errors, I simply pull the drive out (still connected), wet the que-tip, and clean the head. Of course, YMMV and I usually keep a decent supply of spare disk drives around because such rough treatment can only go so far.

August 3, 2012 – Happy 35th Birthday, TRS-80
On August 3, 1977, at a press conference at the Warwick Hotel in New York, Radio Shack announced the TRS-80 Model I. They expected to sell 600-1000 units the first year … and we all know the rest of the story.
Happy 35th Birthday, TRS-80!
May your legacy continue to shine brightly in our hearts.

Those Control Data disks which were David Cooper so masterfully read were part of a disk set which Robert David was kind enough to send. I have started going through those disks and came across the first found copy of: Radio Shack Stockpak (CAT 26-1507), Adventure International’s Airline, and v1.41 of Lifeboat CP/M, in addition to the missing SETUP file from Radio Shack Accounts Payable (CAT 26-1554).
As a reminder, if you have TRS-80 disks lying around, please contact me to convert them to DMK; there are still VERY many files which have not been found, and they could well be sitting in your collection 🙂 Thanks!

August 29, 2012 – New Virtual Disk Conversion Utility
Click to Enlarge
Aaron Brockbank has written a Windows utility to convert from TD0 (Teledisk Format) or IMD (ImageDisk Format) to DMK format. The file can be downloaded from the Virtual Disk Utilities Page.
Thank you, Aaron!
September 5, 2012 – TODMK Utility Updated
Click to Enlarge
Aaron Brockbank has updated his “TODMK” utility to v1.03.20. Changes are:
- Fixed DMK import and Export
- Fixed TD0 import
- Changed DMK export to write a copy of DMK file
- Exports CRC and BadID sectors as read, doesn’t attempt to ‘fix’ nor ‘repair’ them
- Added D88 Format Compatibility
While all these features are great, what Aaron has in store for this utility is mind blowing.
The file can be downloaded from the Virtual Disk Utilities Page.
Thank you, Aaron!

September 12, 2012 – TRS-80 on FPGA – Thoughts?
Michael, a site visitor, has some experience with FPGA’s and is wondering if anyone out there in the Interwebs would be interested in building a new Model III or IV (i.e., real Z-80, real RAM, fpga for glue logic, rom, serial port, video & keyboard, and a floppy disk emulator). Please sound off in the comments.
September 12, 2012 – New Searchable Database – ORCH-80/85/90
Click to Enlarge
A searchable database of the archived ORCH-80/85/90 files has finally been created, and can be found on the ORCH-80/85/90 page.
Regrettably, the copyright code has not yet been modified (110 years to go, folks), so there can be no downloads.
September 15, 2012 – VDK-80 v1.5 DSK/DMK Utility
Click to Enlarge
Miguel Dutra’s TRS-80 Virtual Disk Kit utility has been updated to v1.5. The new version includes the following changes:
- Fixed a file corruption issue in the NEWDOS/80 module. If a file occupies more than one extent, the program accesses a wrong sector when crossing extents.
- Fixed a file corruption issue in the TRSDOS 4 and RAPIDOS modules. If a disk is formatted as double-sided but the DOS is occupying only one side, the program incorrectly accesses sectors in the other side.
- Added two new command line switches that control whether the disk is supposed to be single or double-sided.
- Disabled all functions in the CP/M module, except DIR. This module is still under development.
- Fixed a disk detection issue in the JV1 module. Now the program properly detects disks that contains 400, 720, 800 or 1440 sectors, ranging from 34 to 96 tracks.
The file can be downloaded on the Virtual Disk Utilities Page.

October 10, 2012 – “DiskManip” Utility Updated
Click to Enlarge
Aaron Brockbank has updated his “DiskManip” (formerly “TODMK”) utility to v1.0.6.40. Changes are:
- Bug Fix: CRC calculation for Single Density disks is now correct.
- New Feature: DMK Repair* by merging two different DMK images into one.
- New Feature: Import real Double Density (NO SD) disks into DMK and D88 formats using the built in floppy disk controller (provided “fdinstall” is installed beforehand).
- New Feature: Automatically determines drive size (as in 8in, 5.25in, 3.5in) and density (SD, DD, and HD).
- New Feature: Analyze (experimental). Display directory of Model II disks (TRSDOS 1.2 and 2.0, LS-DOS 6.3.1 and DOSPLUS II A.00).
* This is a biggie folks, if you have 2 DMK reads with different errors (say one disk image had a bad track 11 and another had a good track 11 but a bad track 22) it will automatically create a DMK which uses the good tracks/sectors from the different reads.
The file can be downloaded from the Virtual Disk Utilities Page. Thank you, Aaron!
October 11, 2012 – “DiskManip” Utility Updated
Click to Enlarge
Aaron Brockbank has updated his “DiskManip” (formerly “TODMK”) utility to v1.0.6.41. Changes are:
- Bug Fix: Single Density “FA” DAM is now read and written correctly for DMKs
- Bug Fix: Cosmetic changes to the User Interface
The file can be downloaded from the Virtual Disk Utilities Page. Thank you, Aaron!

Click to Enlarge
Arnold Gross has let me know that he and Rik Pierce hold the copyright to NAME THAT SONG (a musical quiz game) and that they are permitting it to be available for posting for everyone to enjoy.
Since TRS-80 disks are very unlikely to hold data for the (approximately) 110 years of copyright; if anyone else is holding a copyright in TRS-80 software that they are willing to allow people to download, please contact me.
October 20, 2012 – Play ORCH-80/85/90 on FOO

November 5, 2012 – Metatronics Extent-80
Scot Silvestri provided some pictures of a Metratronics Extent-80 he found in the trash. The Extent-80 apparently allowed for up to 8 disk drives on a Model I.
The product announcement in the 12/81 issue of 80 MICROCOMPUTING read …
“Metatronics (a subsidiary of Meta Technologies Corp., as of September 1, 1981) introduces a unique device allowing the connection of as many as 8 disk drives to a TRS-80 Model I computer. Its integrated design is compatible with application software running under VTOS, LDOS, NEWDOS/80, NEWDOS+ and TRSDOS 2.3. Features include a U.L.-approved power supply, power-monitor LED, operating environment protection circuitry, high-impact metal case and gold-plated contacts. Complete with instructions and patch program diskette for configuring your favorite operating system.”
Glenn Emelko advised …
I designed this product for MTC, and did all of the OS patches for TRSDOS, LDOS, and Newdos/80 personally. The device decoded the four drive address lines so that codes 1, 2, 4, and 8 (0001, 0010, 0100, and 1000) addressed the first four drives 0-3 directly. Other combinations of the drive select lines then selected subsequent drives allowing addressing of drives 4 to 7 (iirc it was 0011, 0101, 0110, and 0111 respectively), and we internally experimented with a 15 drive system using 8,9,A..E for the next drive numbers but never released it that way. One code 0000 was reserved for no drives selected. The operating system patches were tricky but once complete it worked great.
