System Source Workshop - bringing an OSI Challenger 1P
Folks, I’m bringing parts of an OSI Challenger 1P that I hope to get running and assembled. I bought this at the Berryville VA hamfest years ago. It was in a home-built case that was falling apart. There were quite a few mods to the C1P, I think there is a custom monitor ROM with a selector switch, etc. I hope to remove the mods, get it back to stock configuration. It also has the expansion board with additional RAM, floppy controller and a floppy disk drive. I have proper OSI cases for both the C1P and disk drives. Hopefully, I’ll get some of it working! -Crawford
Crawford, You probably want to make sure you have a 2716 with CEGMON in it -- it's a *significant* improvement and if you've got something else in there, it's probably what you ought to troubleshoot with.

Would love to find a C1P or a super board 2 in a C1P case with the memory expansion and floppy drive board. Now, I wish I would never have sold mine in the mid-2000s. I sold a lot of OSI documentation and magazines and what not too. Now, I pine that I did that - lol. You don't find those things on EBAY, or at least very often.
