I have one that I've upgraded to an AMD K6-2.  Works just fine.  Had to
replace the processor daughter card with a Type-IV 90MHz Pentium one, then
used an interposer.

Do you want a different NIC?  I have some spare 10Mbps ones I could let go
for shipping.

I helped out with that SCSI driver.  8-)

NetBSD support for the IBM INT13H SCSI adapters is currently being written
(by Jaromir Dolecek).  If you want a disk driver that works *right now*,
go on ebay and get yourself an Adaptec 1640K.  You could get an IBM
ESDI/A, but it's kinda slow by modern standards, and big disks are hard to

It's also quite upgradeable.  Processor on the daughtercard, and all.
