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 4, 2010 – More Zaps / Tips / Tricks

Those of you who are on comp.sys.tandy (which should be all of you) probably know that I have uncovered a notebook I kept back in the day which had weird routines, pokes, peeks, factoids, etc. I have been updating the Zaps/Mods/Pokes/Tricks pages accordingly, and envision getting the notebook contents onto the site.


February 10, 2010 – Lode Runner for the TRS-80

Mark McDougall has ported Lode Runner from the MSX computer (another Z80-based micro) to the TRS-80 Model 4/4P with MicroLabs Grafyx Solution hires board.


February 11, 2010 – Question

Update: Thanks to all those who responded.

Does anyone out there have a working Model 4P? If so, please contact me.


February 11, 2010 – Update to TRS32 Emulator

Matthew Reed has updated his wonderful TRS32 Emulator to v1.22. This update includes:

  • Improved emulation of hard drive when formatting with NEWDOS/80 2.5
  • Improved compatibility of text paste
  • Miscellaneous improvements and fixes

February 17, 2010 – Update to TRSTOOLS

TRSTools is a utility written by Matthew Reed that makes it easier to work with virtual disk images. Matthew has updated his TRSTOOLS utility to v1.01. The new version supports emulated hard drives as well as incorporates bug fixes.

The changelog includes:

  • Added support for virtual hard disks in both LDOS and NEWDOS/80 formats
  • Greatly improved the NEWDOS/80 support
  • Improved the recognition of marginal disk formats
  • Added the ability to view EDTASM source files
  • Created a new format for TRS-80 memory card interfaces and added support for it within TRSTools

The new version can be downloaded from the DSK and DMK Image Utilities page.


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.


March 18, 2010 – New DOSPLUS 3.5 Command Reference

The site has been updated to include command references for DOSPLUS 3.5. The page is still under construction as far as I need to add information ABOUT the DOS, but the command reference is complete.


March 24, 2010 – Symbolic Z80 disassembler for TRS-80 CMD files for the PC

Matthew Reed has just released Z80Disasm, a new symbolic Z80 disassembler for TRS-80 CMD files.

The disassembler is a freeware Windows-based command line utility that makes it easier to develop TRS-80 software on a Windows machine.

Z80Disasm can read CMD files from the Windows hard drive or off of a TRS-80 .DSK file, and it supports MISOSYS-style screening files for maximum flexibility.

Z80Disasm can be downloaded from Matthew Reed’s Z80Disasm Page [Hotlink Deleted].


March 31, 2010 – Update to TRSTOOLS DSK/DMK Import/Export Utility

Matthew Reed has released v1.02 of Windows GUI DSK/DMK image utility TRSTOOLS.

The changelog includes:

  • Greatly improved the recognition of some marginal disk formats
  • Added a new Z80 disassembly viewer as the default for CMD files
  • Added the ability to switch between different file viewers
  • Fixed the incorrect window sizes with larger DPI values
  • Fixed the problem encountered when viewing blank binary 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 23, 2010 – Update to TRS32 Emulator

Matthew Reed has updated his wonderful TRS32 Emulator to v1.24. This update includes:

  • Eliminated “Parity error during read” errors sometimes generated by NEWDOS/80 while formatting double-sided virtual disks

  • Corrected behavior when pasting TAB characters

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.


July 11, 2010 – New addition to the TRS-80.com Family

Although not TRS-80 related, I would like to announce the newest member of the TRS-80.com family … a 4 week old blue eyed siamese/tabby mix (a rescue) …


July 20, 2010 – TRS-80 Virtual Floppy Disk Manager Updated

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


August 2, 2010 – New Downloads thanks to Vernon B Hester

Vernon B. Hester, author of MultiDOS and other wonderful programs, has made his software and manuals available:

  • Astrocal Manual (5th Edition) – DOC Format
  • Astrocal Manual (5th Edition) – PDF Format
  • MultiDOS Manual – DOC Format
  • MultiDOS Manual – PDF Format
  • Zeus (9th Edition) – DOC Format
  • Zeus (9th Edition) – PDF Format

When my host fixes my SQL upload, and I can get into the TRS-80 Archive Lookup, I will post the corresponding software packages here for download.

Also as previously noted, Vernon has a blown Model 4 power supply, which is preventing him from providing updated software. Any help is appreciated.


August 3, 2010 – Broader Net

If you were the author, and are the copyright holder, of TRS-80 software and would like to give me permission to post your stuff, please email me.

Who knew that the anniversary of the TRS-80 would be the day where some downloads came back online.


August 3, 2010 – More Downloads

Wayne Westmoreland & Terry Gilman have given the express ok to put their stuff online as well; so tonight look for their wonderful software as well.


August 3, 2010 – New Downloads

Vernon Hester’s downloads are live (so when doing an archive search you will get hotlinks with the findings). Since Scott Adams had long ago (and also today) allowed me to post his adventures, those links will go live tonight as well. If I can think of other authors who have authorized release, I will move those files over as well.


August 3, 2010 – Wired.com story

Since today is the anniversary date of the TRS-80 launch, wired.com has done a story which is on their front page today. The article is here [Hotlink Deleted]. Wish they would have consulted with me first, since they mis-attribute the historical accounts to me when I didn’t say them (lord knows who did). I am embarrased I didn’t realize it was the anniversary though 🙂


August 4, 2010 – More Downloads (Dennis Bathory-Kitsz)

Dennis Bathory-Kitsz has given the ok to put his programs online.


August 6, 2010 – More Downloads (Lazywriter)

David and Theresa Welsh have given the ok to put Lazywriter online.


August 7, 2010 – More Downloads (Jon Bokelman / Orchestra)

August 8, 2010 – More Downloads (Big Five)

Bill Hogue has given the ok to put most of the Big Five software online.


July 30, 2010 – Free Daisywheel for Local Pickup ONLY

TRS-80 Daisy Wheel II printer free for local pickup from Colorado Springs, CO but arrangements could be made to meet in Denver, Colorado.

The person with the printer advises that it does not have the daisywheel, but it has the ribbon and everything else seems to be intact.

First come first served; I will put you in direct contact in the order I am emailed.


August 8, 2010 – Free DMP2100

TRS-80 DMP2100 tractor feed printer (worked when last used) free for local pickup from St. Louis Park, MN but is willing to ship for the costs of pack & ship.

First come first served; I will put you in direct contact in the order I am emailed.


August 14, 2010 – TRS-80 Virtual Floppy Disk Manager Updated

Miguel Dutra has released v0.7 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:

  • CLI: Could not recognize the parameters “-td2” and “-td3”
  • CLI: Crashed when “-k” was used with long file names
  • CLI: Internal Win2Trs routine generated some ill-formed file names
  • CLI: Internal Dump routine now prints blanks instead of dots in the ASCII column data
  • TRSDOS1: Caused an abrupt program termination when allocating granules
  • TRSDOS3: Caused an abrupt program termination when allocating granules
  • NEWDOS/80: Created files with less than the requested space
  • NEWDOS/80: Improved disk compatibility through better PDRIVE handling
  • DMK: Improved disk compatibility through better geometry detection and sector addressing
  • Other: Granule allocation routines failed to properly determine the available disk space
  • Other: Improved GetFileDate routines to get date values with as little modification as possible
  • Other: Improved OS detection routines to reduce the number of wrong identifications

September 5, 2010 – TRS-80 Model 4P – Free for Local Pickup or Pay Shipping

TRS-80 Model 4P is free for local pickup in Oconomowoc, WI or, for those who do not live in Oconomowoc, the cost of pack and ship. Normally I would say to email me, but the owner has advised a number of sites of the availability, so all I can say is, if you want it, email him quick. His email is leemil at att dot net.


September 7, 2010 – Flash Emulator

Alain Boudreault is working on a TRS-80 emulator running in flash player (using flashbuilder 4 mxml/as3 as the development tool). Eventually, it will emulate a MODEL I Level II BASIC with floppy drives, although the emulator is currently working in beta without floppy emulation.

A video of the emulator is available at: http://www.youtube.com/watch?v=eoXQssEC_8I [Hotlink Deleted].


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:

  • Esoteric DOS v2.11 for Model 4
  • 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.

September 24, 2010 – New ROM Hunt

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

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

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

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 5, 2010 – New Guestbook

The Guestbook has been replaced AGAIN, as it became a spam magnet. Links have been updated. New guestbook is here and the old guestbook, converted to HTML for posterity, is here.


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

December 10, 2010 – 3 TRS-80 Model III’s for FREE (Local Pickup Only)

A site visitor has 3 TRS-80 Model III’s which he would like to give away free for local pickup. He has not tested extensively, but advises that they do not power up as currently configured. If anyone is interested in picking them up from Yorba Linda CA 92886 please contact me.

<head>
<body
onload="trsEmu.screen('scrn').button('btn').perf('graph').focus();">

January 17, 2011 – Tandy Annual Report 1977

Thank you David Sutherland for winning the packet given out to attendees of the Beverly Hilton TRS-80 announcement in 1978. It contained the 1977 Tandy Annual Report, the first TRS-80 catalog, and a bunch of handouts.

David was nice enough to drop ship his eBay winnings to me first for scanning.

March 27, 2011 – eBook Version of Priming the Pump

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). These versions include illustrations in color (those that originally had color — some illustrations are original black & white photos, but we have many old magazine ads that are color, but appear in the printed book as black & white). 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

People who don’t have an eReader can still view these versions by downloading the “Kindle for PC” app or the “Nook for PC” app available at amazon.com or barnesandnoble.com.

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.

June 27, 2010 – Update to TRS32 Emulator

Matthew Reed has updated his wonderful TRS32 Emulator to v1.26. This update includes:

  • BUG FIX: On some Windows 7 systems, a synchronization conflict led to sluggish responses by the user interface. This problem has now been fixed.
  • BUG FIX: Keyboard handling is now improved to make certain SHIFT+CLEAR key combinations more consistent.

June 28, 2011 – Updates to Matthew Reed’s DMK Utilities

Matthew Reed, author of the TRS32 emulator, has updated his DMK and DSK Management Tools: TRSREAD / TRSWRITE (Command Line) to v1.29 and TRSTOOLS (GUI) to v1.06.

Changes:

  • Fixed: Faulty format detection routine that was rejecting many NEWDOS/80 disks is now fixed.
  • Added: Read-only support for the most common Montezuma Micro and LNW80 CP/M formats.
  • Added: Read-only support for Color Computer RSDOS disks.
  • Changed: The file properties and disk properties dialog boxes now only show information pertaining to the file system.

June 30, 2011 – Update to TRS-80 in Java

Peter and George Phillips’ TRS-80 Emulator in Java has been updated to v1.3..


July 10, 2011 – Installing a 3.5″ Drive

Larry Kraemer has provided instructions on how to install a 3.5″ standard ibm floppy drives in a TRS-80 Model III or 4. The file is on the Hardware Modifications page.


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.


July 15, 2011 – Model 4P and DMP 110 Free for Seattle Pickup.

I stumbled upon a new TRS-80 site, trs-80.org.uk. They have a few links, and some downloads, but most notedly, a currently published TRS-80 newsletter, called TRS8BIT, available for download.

I have put together a TRS8BIT cover page here, but like all the other pages, there are no downloads. The address is trs-80.org.uk should you wish to download.

Always good to see new TRS-80 sites … wishing them well!
