Have you looked at the schematics and drivers for the Ukranian
QBUS IDE interface?

You could use one of the IBM Microdrives in that case. That would be
kind of interesting. Small, fast, and removable.

I've been thinking of building the Ukranian IDE adapter. If I do,
I am thinking of building it on a quad card and putting the drive
on the CD side to use it with my Q-CD backplane. I'd put the
DZQ11 and DELQA above the card so there will be two empty CD slots
above the drive.

Now that would be handy.

If I could just find a good, MSCP QBUS SCSI card I'd not need to
bother, though, but they are hard to find and expensive. I'd
trade my space Alphastation 200 4/233 for one.
