Analyzing The 6502 With Python And Cheap Dev Boards

The Before Times were full of fancy logic analyzers. Connect the leads on these analyzers to a system, find that super special ROM cartridge, and you could look at the bus of a computer system in real time. We’ve come a long way since then. Now we have fast, cheap bits of hardware that can look at multiple inputs simultaneously, and there are Open Source solutions for displaying and interpreting the ones and zeros on a data bus. [hoglet] has built a very clever 6502 protocol decoder using Sigrok and a cheap 16-channel logic analyzer.

This protocol decoder is capable …read more
