Dave Huffman has given permission to make his RAMDISK drivers for the Model 4 available for download; so those search results are now live. Any other author that would care to do the same, please feel contact me!


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

In light of Matthew Reed having created a few utilities that do not fit into other categories on the site, I have created a new Misc Utilities page.


February 13, 2011 – Updates to Matthew Reed’s TRSREAD Utility

Matthew Reed, author of the amazing TRS32 emulator, has updated his DMK and DSK Management Tools: TRSREAD / TRSWRITE (Command Line) to v1.31.

Changes:

  • Fixed: TRSREAD could sometimes crash when displaying the directory of a damaged disk with corrupt date entries. This bug has been fixed.

March 5, 2012 – New TRS8Bit Newsletter

Dusty has released his March 2012 issue of the TRS8Bit newsletter on his trs-80.org.uk web site. You can find all of the issues on his downloads page.


March 6, 2012 – Updated TRS-80 Archive Search

Updated the TRS-80 Software Archive page to point out that there are, in fact, downloads available for files where express permission was given. Added a second (optional) description line for those who want to do a boolean AND search.

If you are a copyright owner who has entries on the list, and wish to allow your program to be available for download, please contact me.


March 9, 2012 – Site visitor looking for ORCH-90

A site visitor has approached me looking for an ORCH-90. While I would not normally post such requests, there never seems to be any on eBay so I wanted to post a news item. If you have one you are willing to sell, please contact me.

April 3, 2012 – New TRS-80-related Android App (Live Wallpaper)

[Android Live Wallpaper]

Rob Cole has pointed me to an Android App (well, live wallpaper) on the Android Market called “TRS-80 Android Live Wallpaper.” The company describes the app as:

“Now TRS-80 computer fans can personalize their android devices with something TRS-80 related! This recently released interactive live wallpaper from GNOTSOFT features the android that we all remember and love–an icon from our TRS-80 days!

This fun wallpaper features a lone android patiently looking around while you go about your business. It’s also interactive and will look over to where you touch on the screen!

The developers at GNOTSOFT have a deep appreciation for the TRS-80 and are excited to be developing for the android platform. Many more fun projects are underway! All feedback and suggestions are welcomed.”

The market entry indicates it requires no “Special Permissions” and costs 99 cents.


April 8, 2012 – How to Replace a CRT

Ian Mavric, who is also the Australia source for TRS-80 disk requests and who repairs TRS-80s, has put a YouTube video up entitled “How to Repair a TRS-80 CRT in a Model 3 or 4”. You can watch it on the right.


May 2, 2012 – TRS-80 Software Library Cover Scans

Ian Mavric has scanned a bunch of the TRS-80 Software Library product sheets. The cover scans can be found on the Product Catalog Page.


May 10, 2012 – TRSEMU v1.4 – Model III Emulator in Java – Updated

Peter Phillips, twin brother of George Phillips, has released v1.4 of his Model III in a Web Page. You can see it in action at http://people.cs.ubc.ca/~pphillip/trs80.html where you can also download the few files necessary to implement your own Model III emulator in a web page.


May 11, 2012 – Using a PC In Lieu of TRS-80 Parts

It is getting harder and harder to use real magnetic media in a TRS-80 (mono cassette players, disk drives with good heads, a source of 5.25″ low density disks). There are a couple of solutions out there, and I have created a new page devoted to hardware and software products which will substitute for having to use magnetic media in a real TRS-80. That page, which is listed on the left under the “Emulation” heading, can also be found here.


May 12, 2012 – PIC32 … a Tiny Hardware TRS-80 Emulator?

[DuoMaximite Mini]

While there is not a lot of information available, it seems that Ken Segler has created something called a PIC32 TRS-80 Emulator.

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 24, 2012 – Interview with Lewis Kornfeld from 1980

Ian Mavric has found a 6 page Interview with Lewis Kornfeld from 1980. Thanks!


May 24, 2012 – New Downloads from Nels P Olson

Nels Olsen has allowed his software to be downloaded. To check it out go to the TRS-80 Software Archive Search and search for Nels P Olsen in the Author/Publisher field. Download links are live. Thanks Nels!


May 29, 2012 – Tim Mann’s site down; Tim looking into it

For those concerned about Tim Mann’s site being temporarly down, rest assured that Tim is looking into it and that we do not have another Dave Keil situation going on.

Update: Problem has been found and Tim’s site should be back up shortly.


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.


May 31, 2012 – SuperScripsit File Structure Description

A description of the file structure and byte layout of SuperScripsit files has been added to the TRS-80 Zaps/Patches/Pokes/Tips Page. A direct link can be found here.


June 4, 2012 – Non-working CoCo

If anyone wants a non-working CoCo for the cost of shipping, please let me know. It is currently in Santa Barbara, California. Emails forwarded in the order of receipt.


June 5, 2012 – TRS-80 Assembly Language Made Simply Book – Download

Earles McCall has reminded me that he is the copyright owner of TRS-80 Assembly Language Made Simple and that he had given permission to post his book. Other than the foregoing link, the book is now downloadable from the Books Page. Thank you very much Earles.


June 6, 2012 – 3-D Android Nym by Leo Christopherson

Leo Christopherson (R.I.P.) has released PC and MAC versions of his Android Nym program.


June 7, 2012 – Adventure International Added to Catalog Search Page

In addition to Radio Shack catalog entries, Model I/III/4 entries from the few adventure international catalogs I have have been entered into the Catalog Search Page; in all cases, with scans of the actual entry.


June 11, 2012 – MultiDOS History / Info / Download Pages

I have been working with Vernon Hester for over a year to compile the history of MultiDOS, provide downloads for existing copies of MultiDOS, and include any information for each release that Vernon could remember. While the pages (there are FIVE) are still in the works, Vernon’s schedule has been a bit hectic, so while the pages are not yet done yet, he has allowed me to make them public. The link can be found on the right navbar under DOS’s or Right Here. Thank you Vernon!


June 12, 2012 – New TRS8Bit Newsletter

Dusty has released his June 2012 issue of the TRS8Bit newsletter on his trs-80.org.uk web site.


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.

  1. 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.
  2. 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.
  3. 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.
  4. 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 10, 2012 – Color Computer Font Released

Ray Larabie of Typodermic Fonts has released the Color Computer font.. Note: Downloading requires registering at fontspring.com.


July 12, 2012 – Lightbox Bug Fixed

Thanks to Al Petrofsky, I have been advised of an update to the Lightbox plug in which will remove the bug of having pictures appear MUCH lower. The fixes have been made to the Catalog Search page and Archive Search Page. Thanks, Al.

July 30, 2012 – Control Data Diskettes

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

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.


August 3, 2012 – Happy 35th Birthday, TRS-80

Matthew Reed, author of the TRS32 emulator and other invaluable tools, has a very nice historical write up for the 35th anniversary.

August 6, 2012 – Do YOU Have TRS-80 Disks?

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

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

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 9, 2012 – Model III

A Model III is available for the cost of pack and ship from Pennsylvania. Details are on the TRS-80 for Free page.


September 10, 2012 – New TRS8Bit Newsletter

Dusty has released his September 2012 issue of the TRS8Bit newsletter on his trs-80.org.uk web site.


September 11, 2012 – Model I – Free for Local Pickup Only

TRS-80 Level II, complete with CPU, dual disk drives, monitor, and printer is available for LOCAL PICKUP ONLY in Chagrin Falls, OH.


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

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

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

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

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!


October 16, 2012 – Another Author OK’s Download – NAME THAT SONG

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

Jon Bokelman, one of the creators of the ORCH-80/85/90, etc., has written a plugin for foobar to play Orch and Piano files.


October 23, 2012 – Lots of ORCH Dupes Identified

As Jon Bokelman fine tunes his plugin for foobar to play Orch and Piano files, he has written a program to check the compiled output of an ORCH text file and has identified about 1,600 duplicate files in the ORCH archive and in the Searchable ORCH Database.

John McGinty’s lecture at this past years GDC, entitled “Inspirations from the Trash: The TRS-80’s Lost Game Designs” has been posted to the GDC website (WARNING: Be prepared to here it called the TSR-80 throughout the lecture). Thanks for keeping the spirit alive, John.


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.

November 6, 2012 – Looking for Driver.

Does anyone out there have a copy of the LDOS 5.3 MSCSI5/DCT driver and formatter which is needed to run a Misosys hard drive. Thanks!

November 20 – Tutorial: Reviving a TRS-80 which has Sat Idle for Decades

Ian Mavric has created a YouTube video on what to do to revive a TRS-80 which has sat idle for decades. Many many people ask this question, so Ian was kind enough to do a video.

The video covers:

  • Opening the Model III and looking for stuff inside
  • Re-capping the power supply
  • Keyboard repair
  • Disk drive maintenance
  • Putting it all back together and testing it

December 19, 2012 – Updated ORCH Player/Utility

Jonathan Bokelman has updated his ORCH90CD utility to v2.3. ORCH90CD is a command line ORCH player, but can also suss out a CRC calculation of a compiled ORCH for testing for duplicates. Instructions and download links can be found in the “ORCH-80/85/90 Players, Programs, and Downloads” section of the ORCH-80 page.


December 20, 2012 – Harry McCracken on TWiT Network

Eric Hacker has let me know that this week’s “Triangulation” show (#83) on TWiT Network featured an interview with Harry McCracken. Harry’s first computer was a TRS-80 and he has been very pro-TRS-80 in his reporting for PC World, Technologizer, and now Time Magazine.
