[The basenote asks if a new mechanism can be put into a Supradrive 20].

well, maybe. You'll have to open it up and look. It may be an integral
controller drive (unlikely); it may be a controller that won't talk to
other drives decently (possible); it may be some custom weird setup.

	Basically, you'll probably see:

	1) Cable to Atari DMA port
	2) ACSI to SCSI converter board of some time
	3) 50 pin SCSI cable
	4) Disk Controller
	5) 34 & 20 pin cables to drive
	6) drive
	--
	7) power supply

	inside the drive, hooked together in that order.

	*Generally*, if you know what you're doing, you can unhook the 34 and
20 pin cables & power, put another mech in, and it'll go. But there are all
sorts of gotchas here possible. If you have a particular drive in mind, I
might be able to tell you; I've been "got" a lot.

	Anyway, open it up and tell us what you have; it'll help determine
what you can do.

	I took my SH-204 and made it into a 80-odd meg system, and the base
of a 240 meg system (4 x 60). Those components can go a long way with a few
clamp-on 50 pin connectors and cable.
