  Mine's running an old ISA Dell I/O card with 2x 5.25" floppy drives and a
Seagate 280MB IDE Medalist hanging off it. I have the bookmark for the
instructions somewhere, but it boils down to needing an IDE adapter that's
pretty brainless, and that either has no serial ports or can be turned off,
a Seagate Medalist <2GB, a goat, and 2 plucked chickens.

  I seriously did have to beat the drive repeatedly with the AOS LL-format
utility to get it running. After it took a BSD filesystem, it then
happily accepted TLC from the VM tools.

  Apparently, *only* the Medalist line supports an arcane instruction or
sense bit or something that the ESDI adapter used and the system firmware
wants to see. And, at this point, I'm not sure that a <2GB Medalist
qualifies as "easily obtainable". ;)

  At that point I was able to power up the RT without dimming my office
lights. Three very tired E70s suck some serious amps spooling up.

  I'd dearly love to snarf a mouse and a Matrox graphics adapter for the
thing, but it's one of my pride & joy items just as it is.
