Hello my patrons! Next up on the main channel, I'm back on the Agfa Compugraphic 9000PS. I honestly never imagined I would make any follow-up videos on what I considered a parts donor, but here we are with part 3!In the last video I finally figured out that this board was printing error messages on its RS232 port. In this video I dig into figuring out exactly what the error means and how to go about fixing it, and yes: this involves gaining access to the original "Atlas Monitor." This turned out to be a really fun exercise in exploring unknown hardware!Let me know your thoughts. Since finishing this video, I have since done more work on the AGFA-MON, added capabilities and bug fixes so that it's even more capable. Should I make another follow-up, maybe something on the second channel? That's it for now, thanks for all the support! Direct link: https://youtu.be/--LbJZPreNc
