Osborne-1 with prototype-based motherboard

Am just posting this as I am hoping someone out there knows someone who was involved with Osborne back in the day to find out more this Osborne 1 motherboard I found in a low serial O1 I picked up for $100. I reached out to Lee Felsenstein on it and he suggested it was related to the boards produced for the 10 prototypes Osborne built, or a derivative of them. He couldn't say for sure how it ended up in mine. But I was hoping if anyone knows any Osborne experts that might help me on this - it is not currently working and I'm hoping to find schematics, etc to get it going again. Obviously with the radical differences in layout, the schematics for the production motherboard isn't terribly helpful. I've posted a blog about it here with a picture of the board for those curious: http://bradhodge.ca/blog/?p=1186 Brad
