CoCoBan is a self-discovery action puzzle game derived from Sokoban and Picoban with a few added twists. Use the keyboard to push or pick up objects to make your way to the green emerald goal. Game progress is automatically saved to disk when you advance a level. Be sure to turn up the volume to hear the sound effects! CoCoBan…
I think I missed the memo when version 1.0 of XRoar came out back in November 2021. I knew the emulator for many years and since I am a macOS user, it was always a good choice for me to emulate the CoCo 2, since, from my knowledge, it emulates the Dragon and CoCo 1 and 2. Because I am…
I got my first computer when I was 13 years old, and it was a JR Sysdata, a TRS-80 Model I clone. I loved that machine and learned a lot from it, but as soon I saw the CP-400 advertisements with its silver fancy design and all those colors, I started the campaign to upgrade to one as soon as…
The Retro Hour podcast, although it has most of its focus on retro gaming news and interviews, it also covers, from time to time, different technologies from the old days. I guess on could say that one of the advantages of being a very professional and well-known podcast (well-deserved btw) is the ability to attract very important guests, usually figures…

Wordle is everywhere, except on TRS-80’s. The TRS8BIT 2022 competition aims to change that. It has two tracks called Beauty and the Beast. Beauty entrants will make their own version of Wordle for the TRS-80. They’ll be judged on how fun and pretty they are. It doesn’t need to support the full dictionary so you can concentrate on looks. Use…
One of the most expected and respected contests in the retro computing community is happening again! The 11th of the BASIC 10-Liner has started and already waiting for your submission. This edition’s rules are pretty much the same as last year’s. BASIC games can be written for all 8-bit computers, as long they are line-oriented dialects. As usual, the PUR-80…
It has only been a week since Roger Taylor announced his project to reverse engineer the custom ASIC Radio Shack used in their Color Computer 3 and we have already learned a few interesting things. He sent two versions of the “GIME” chip off to be opened up and photographed under a microscope. These images revealed some messages etched in…
When Radio Shack released their third and final version of the Color Computer, the Tandy Color Computer 3, it included a custom ASIC chip. This chip, called the GIME (Graphics Interrupt Memory Enhancement), replicated most features of the Motorola 6847 video display generator chip used in earlier models. It also added new features such as higher resolution graphics with more…
Well, this is getting a bit silly. Awhile back I posted an article discussing the alternate color set available in the 32 column text mode on a Radio Shack Color Computer. It was (mostly) available from Extended Color BASIC via the SCREEN command. This allowed having a screen that was either “nuclear green” or “whatever color the other is”. Then,…
