Absolutely. I've modified a couple Lisa's between 800k and 400k drives and I know they're not interchangeable. The trouble now is finding a spare 400k drive. I also want to find and replace the ROMs with genuine Apple ROMs and see what I can do about the case. As I've said, I can work with it but is completely usable right now
I'll ask here first: Does anyone have a 400k 3.5" drive and/or original Mac 128k ROMs? If so, PM me.
With that said, I still love it. Thanks again.
