So, buy a new motherboard and plug your CPU into it. :-)  A CPU-less
motherboard with PCI or VLB could probably be gotten for less than
$100 in Computer Shopper.

Assuming you don't chose that route, you need either an Adaptec 1542,
or a BusLogic BT545 (their equivelant of the 1542).  Both are ISA bus
cards.  Which also means that, for the time being, anyway, NetBSD
isn'g going to let you use more than 16MB of RAM with them.  That will
be fixed Some Day.

I agree.  That's why I said be careful.  I'm skeptical that you will
find anything as good as a BusLogic or Adaptec controller.  You may
find several cheaper, but You Get What You Pay For...
