The next Manitoba Retro Computer & Gaming club meetup is at the Fort Rouge Leisure Center in Winnipeg, Manitoba on April 12. This is the same one I attended last weekend, along with D. Bruce Moore and David Kroeker. This next one is more themed around the Commodore 128, but I expect a wide variety of machines like they had this past one, which was TRS-80 themed

Coco 1/2/3 (and multi-platform)

1) Coco Town returns with a detailed description on how he got the realtime overlay showing the PMAP’s of all active processes in NitrOS9 working in MAME, that he showed on his previous episode:
https://youtu.be/e-G-pIzkJpc?si=6ez_7u6KGuV4AfVH

2) TRS-80 Retro Programing posted a video of his further progress in his Asteroids style game in BASIC, but hit a problem that he thinks is in the DRAW statement of the explosion, when used to erase the original white version of the explosion graphic with a black version.
https://youtu.be/TtuVSFVjVno?si=HUDKfhT_pgYN-0iO

3) Eddie Malphrus has been collecting original documents for former Tandy engineers (like Jerry Heep). One of the ones he got recently was the original Bill of Materials for the original Coco 1. Some parts have price estimates, others do not:

He also has one for the TRS-80 Videotex data terminal, that came out a few months before the Coco 1 (this particular copy was a revision done August 24, 1980). This also includes documentation “BRIEF DESCRIPTION OF VIDEOTEX OPERATION”:

(Show screenshot from Cocolist: “Coco Fun with tweaking BASIC continues returning numbers.pdf”

7) Allen Huffman posted, as he called it, “A life changing letter” on his Sub-Etha Software blog. This shows both his original letter and the response he got, which got him his job at Microware in 1995 (the creators of OS-9):
https://subethasoftware.com/2025/03/17/a-life-changing-letter/

Dragon 32/64

1) Ciaran Anscomb posted on the World of Dragon forums about some further CPLD programming that he has done based on his SAMx4 project… now the SAMx8. This update includes a new webpage and manual for it. This allows a few things:

full double speed on a Dragon 64 (ie Coco 3 speeds)
support for 16k banked 512K of RAM (with a COMMON flag that fixes the top 8K (including IRQ vectors)
Video RAM can be anywhweres in the 512K, on 32 byte boundaries (allowing smooth scrolling)

4) RetroGamingLoft on YouTube put up a longplay video of Paul Burgin’s September 1991 port of Shanghai to the Dragon 64.

If Paul’s name looks familiar, it is because he also wrote the first Dragon emulator:
