That sounds like a pretty neat board. I don't have a logic probe yet but I'll try to interface with a microcontroller. I'm sure I can find something to do with it. Thank you all for the replies! ?

Hi everyone, I recently bought an unlabeled program pak on ebay. I bought it for the cartridge case but I wanted to see what program it was. Before plugging it in, I opened the cartridge and surprise, there is no ROM inside! It looks like some kind of prototype board with a few sn74ls244n and one sn74ls245n octal buffers. I'm new to the world of electronics (and CoCo) so I was wondering if someone on this forum ever used something similar. I want to know if it can be of any use. Thank you for you help, Charles
