Sounds good. Now, the next question:
How about 2 floppy drives? (the 5.25 inch already there, plus, the
3.5 inch added on (externally, of course, but no problem for me))
Also, what about the high density 3.5 inch drives? - are these simply
more tracks? or do they require more sectors per track?
Thanks in advance.
