I wonder if there's any value in writing a VIC chip and 6502 protocol decoder. Hmmm #commodore


Have you seen Hoglet's 6502 protocol decoder? With little more needed than the databus, it can decode the full 6502 register state and program execution. So a cheap 16 channel logic analyser will do.

It also handles 65816, and he's done versions for Z80 and 6809 too. And 6309. Even found a previously unknown extra register in that!

Can install on a Raspberry Pi if your OS is too slow to keep up.

See for example
