In past lives I have used some pretty sophisticated logic analysers to do debugging of complex digital systems (ie RISC CPUs, memory, PCI interfaces etc).
Fast forward to today this is now a home hobby and mainly looking at vintage computers and arduino systems. I am in need of a logic analyser for my home lab but as I will not use this very often I would like to seek advice on what my options are for cheap(ish) open source / ebay / Aliexpress options.
I do not need hundreds of channels and Ghz timing. I am thinking I probably need enough channels to probe some address and data buses and a few enable signals. Probably in up to 20Mhz but a bit higher would be a bonus. What I need is something with decent software that I can record traces, decode some addresses and other protocols like I2C/SPI etc.
Suggestions ?
