Yeah, sounds reasonable. However I still have an option :) I have an 1541
with faulty mechanics, but otherwise it seems to work (it has got even
parallel cable connector wired/soldered in).  So, I can replace the actual
drive itself (somehow) with the actual signals from/towards the head, the
step motor, etc with some "emulation" of that, but the original CPU/VIA/etc
can remain, also the original case of the drive, so it can be stylish :)
Maybe that does not need as powerful uC as my first idea, since
CPU/VIA/RAM/ROM of the real drive remain.
