SCSI cards are $200-$300ish for disk compatible ones on eBay, when they
show up. After collecting a few QBUS things I got lucky and obtained
one in a machine. A DSSI card should be cheaper (KFQSA/M7769), if you
can find one and a drive. You could also try to find someone with a
KDA50 and SDI drives (RAxx) or a third-party SMD controller and SMD
drives, or ESDI controller and ESDI drives... there was one of those on
ebay just about a week ago, but it went for more than I'd want to spend.

For now, it'll probably be easiest for you to find some ST251s or ST225s,
and although they're small, you might be able to get an old copy of VMS
onto them. I'm sure you could get NetBSD to fit on a ST251.

RX22? Do you mean an RX33? If so, you can make one from a TEAC FD-55GFR
floppy drive. Some instructions are here:
I remember seeing better instructions somewhere else, but can't find them

As far as a hard drive goes, you could find an ST225 (RD31) or ST251
(RD32), as those seem to be the easiest to find. You'll need to
reformat them, which you can do using XXDP on a PDP-11 or TEST 70 on a
VAXstation 2000. If you can find one but don't have either of the
above, let me know and I'll see if I can help.
