Who would have thought that in 2023 some idiot would write another Tiny Basic for the 6502… Well, I was that idiot… Because: Why Not! It all started as something else… Over the summer just past I wrote a new … Continue reading
For a long time I’ve been writing Mandelbrot programs for fun and recently to act as a benchmark for some retro BASIC systems. The output has been variable from simple ASCII text to high resolution colour graphics. For retro systems… … Continue reading

Previously I wrote about the issues bootstrapping BCPL on my Ruby board and I was moaning about needing a C front-end or “shim” to get BCPL going. So I engaged the little grey cells and worked out a strategy… What … Continue reading
I’ve just watched Dave Murrays demo of his “Vera” video card moving some balls round the screen. Initially confused by how it was working, but now understand that it’s to do with the way the colour works in text-mode, so … Continue reading
