My memory of things was that you first had to swap out the ROMs, then
hang both a SCSI disk _and_ an RD disk off of the machine, _then_
patch a driver for the SCSI drive, then one could restore a saveset
onto the SCSI disk and stop using the RD disk. Kind of a
chicken-and-the-egg issue, but not insurmountable - just tedious.

True enough, but at the time I was fiddling with all of this, I _had_
the uVAX 2000, and RD54s were $800-$1000 each while SCSI disks double
that size were free or nearly so.
SCSI-based VAXstations were nowhere close to free at the time, and I
think a "noname" AT-sized Alpha motherboard was about $50-$100 w/0MB
Given the hardware environment of the time, what I was doing made some
modicum of sense. Now, it'd be just for the exercise of doing it,
especially since if I _really_ just want to run VMS software and don't
care about fiddling about with ancient disks and slow processors, I
can throw a copy of VMS up on simh and get "real" work done (and given
that my previous job was as a(n Open) VMS Administrator, I'm not that
long out of using VMS 8-10 hours per day).
Lately, though, I spend more time per month running simulated TOPS-20
than any flavor of VMS. Gotta finish ordering parts for that PANDA
display so I can show it off.
