I made a... thing...

I found a 1980 Alps #electromechanical #handheld game in a brockihaus for 5 francs, so bought it and took it apart. Putting it back together again was somewhat harder. Thank goodness for 3D printers.

A new version of the #FluxEngine GUI for my floppy disk flux-level reader/writer/analyser is out! It's now basically on a hacked-up version of the #ImHex binary editor, and is immeasurably better than the old GUI (i.e. mostly works, as opposed to mostly not working). Binaries are available for Windows and OSX.

(As a reminder, the FluxEngine client doesn't just work with the FluxEngine hardware but with a Greaseweazle or AppleSauce (the last read only). Or standalone.)

I bought a cheap, modern, toy games console from AliExpress that wasn't a NES clone and reverse engineered it. It turns out to be based around a 8MHz WDT65c02 with 2kB of RAM, embedded into a blob chip, with a really interesting OS.

I made an SDK for it: https://github.com/davidgiven/tony-sdk

#reverseengineering #6502 #homebrew #retrocomputing

I got a #snes It was broken. And then I made a complete hash out of getting it running again. I think this was the most cursed project I've ever worked on (largely, but not entirely, due to my own incompetence, I should add).

Just added #JiffyDOS support for my #vic20 port of #cpm65. It dramatically improves disk performance. Currently it works on a 1541 (with JiffyDOS ROM) and a CMD FD-2000, probably; there's a good chance it works on an SD2IEC as well, but I haven't been able to test that.

I've updated my #cpm65 ports for the #C64 and #vic20. They now have an integrated fastloader for much better disk performance, more RAM, better screen handling, better keyboard handling and are in general much more useful. You get:

- an assembler and disassembler
- two editors
- some demo programs and tools
- a port of Atari BASIC
- binary compatibility with the other 14 CP/M-65 platforms (getting the binaries onto the disk is your problem)
- bugs

I wrote a 3½-channel polyphonic tracker for the Commodore PET:

I spent some time trying to play back digital audio on an unmodified Commodore PET. It even worked, kinda.
