Based on what Retro Erik did for his Olivetti Prodest PC1. (youtu.be/uqIDscWm9C0?... ) I decided to write a TSR to swap the CGA fixed palette to the PCjr’s palette mapper. Here an example for PAC-MAN. #retrocomputing

Working on a new idea. #retrocomputing

As an added bonus I used the PALETTE command and swapped the cyan and magenta colours for light and dark grey and it’s hard to tell your not in 80 column mode! #retrocomputing.

So I totally forgot about this but if you are in screen 2 mode in BASICA (640x200x2) and save the screen buffer (BSAVE). Then switch to screen mode 1 (320x200x 4), reload the screen buffer (BLOAD). You can still easily read the 80 col text that was stored but in 40 col mode! #retrocomputing

I recently uncovered some old backups (~1994) from when I was daily driving OS/2. Here’s an unfinished game I must have been working on.

Spent over an hour searching for a Linux app for 16 colour ANSI art/drawing and could not find good one or one that I could install. Gave up and spent approx 40mins and generated one to my liking using Google AI Studio. Fun yet scary.

This was my attempt to recreate the arcade game “Bank Panic” using PC BASIC on my IBM PCjr, probably sometime early 1996. I recall the robbers were drawn using the DRAW command.

Haven’t played this game for a while. I always liked it but I was never any good. I’m still not.

Here’s my second installment describing a few details of how I created the assets for the PCjr’s 40th animation. whitaker8088.wordpress.com/2025/10/07/i...

Only 18months late but I finally finished a blog post describing some of the design/implementation details for the 40th anniversary for the IBM PCjr whitaker8088.wordpress.com/2025/08/03/i...
