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.
