TRS-80 Trask Talk LIVE is coming up on September 26, 2020 at 5PM Eastern Time (2PM California Time).
In addition to the usual revelry and camaraderie of our typical live show, we’ll be having a few special presentations to make up for the lack of Tandy Assembly this year. 🙁
Arno Puder and Andrew Quinn will be giving a presentation and demonstration of two exciting new TRS-80 projects, TRS-IO-M1 and PocketTRS.
Here are some of the highlights:
- TRS-IO port to the M1
- Supports all features of TRS-IO (FreHD, RetroStore, trs-nic, etc)
- Same code base as the TRS-IO MIII
- Has a 32kB SRAM chip included
- Auto-boot feature
- Fully Open Source
Then, Tim Halloran will give us a short demo and progress report on hacking the CHOMRAtrs.
- Hardware emulation of a MIII
- Display via VGA. Color can be set to green, white, or amber
- Keyboard via PS/2
- Audio interface can be used for game sound as well as cassette input (500 Baud only)
- I/O expansion bus emulation: one can connect external cards such as FreHD
- Has TRS-IO embedded
- Fully Open Source
Despite glacial postal service between the US and Australia and chip shortages, a few of the new CHROMAtrs boards from Ian Mavric are working (based on work by Pascal Holdry). You may not know that Robert S French released much of the software (Ira’s site) and it is possible to obtain the code and work on it. That’s what Tim Halloran has been up to (with help from George Phillips) — in particular making it easier for cassette-based systems to use the board.
So mark the date and time and come join us on Zoom. Everyone is welcome, even fans of other vintage computer platforms. See you on Zoom!
To attend, go to https://us02web.zoom.us/j/86907465958?pwd=a1lLQzFKaGN0dzludU9MWUs2TDhsUT09 at the appropriate time!
Hope to see you there!
A site visitor let me know that there is an estate sale coming up in Eaton Rapids, MI which shows some Model I’s and other items.

First, the podcast TRS-80 Trash Talk # 37 is out now.
“In this episode we discuss a whole bunch of TRS-80 accessories and recent acquisitions. We then talk about the TRS-80 music album “Classical Mosquito” by Robb Murray. Then we dive into some interesting eBay sales of rare TRS-80 accessories. We wrap up with a review of the classic TRS-80 programming book “TRS-80 Assembly Language Programming” by William Barden Jr.”

On this day in 1977, the TRS-80 was announced at a press conference at the Warwick Hotel in New York City!
Does anyone out there have the cassette that came with the ChromaTRS? We are trying to find the software that came with the ChromaTRS on tape. If so, please contact me. Thanks!
- I got 2 shipments of CLOAD tapes, one of which was completely and totally blank. 20 tapes, all blank. I converted the other set, and scanned the media for both. These are all online and available for download.
- In doing this I realized that the tutorial I have for reading tapes used Goldwave, which still exists, but costs. I updated the page to contain step by step instructions using the free program Audacity.
- I also realized that some permitted files were not present and some screen shots, media scans, etc. were missing, so I modified the ever increasingly hard to maintain program I use which generates the SQL based on various file comments other input files to audit for missing things. Hopefully this will keep the missing files and graphics low.
