Osborne-1 with prototype-based motherboard

[Sam O'nella]

Maybe too easy but have you asked the seller if they know anything about it's origins? I'd also guess maybe an employee or it could just be one of the 6 motherboard types as someone else commented. Pretty awesome though with the low serial. Thanks also for the blog. I had no idea about the different designs and cases. 

I'm curious which one I have now.
