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.
Is it just the board layout that's different, or does it appear to be a completely different animal, schematic-wise? (I mean, is there a possibility that the common schematics could still be used for fault diagnosis, despite the different chip locations)
I wonder why the board layout changed? I mean sure there was a lot of unused space in yours, but it's not like the production boards were physically smaller. I'm surprised that additional space couldn't have been used for some other potential future purpose - RAM expansion or whatever.
