my opinion: Waste of Time! if you do get it working, won't it be incredibly slow??

two better ideas:

EEPROM or something that would work just as good, internaly or in a small plug-in cartrige. I think Mike Jan was working on some internal thing like that.

try and get as much info as you can on disk drives from TOSHIBA or IBM and get one of thos 3 1/4 disk drives from a laptop that are half as thick as desktop ones and build yourself a little plug-in setup. I found out that old "TANDY model 3"s are Z80 based and have two 5 1/4 disk drives that have driver boards on them. that probly won't help any, but it's interesting to know. anyway, TOSHIBA can probly help.
