Did they have drives that big then. I think you meant 10 MB. :) So hard remembering what it was like back then.

I still have a 1000HX to which I put in a V80 chip (original CPU on steroids) and a 40 MB hard drive. The hard drive fit the other floppy would have gone but the controller board had to lay in the "expansion" bay at an angle with an adapter cable because there was no room except for their specially made boards which were very few. I believe the bus was laid out like a standard ISA but weird connectors and no room for standard boards. It was about the same size as an Apple IIe and kinda looked like on too.
