[vcf-midatlantic] 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
