My recollection is that the MicroVAX 2000 SCSI

only intended for the tape unit. Whether its performance beats an RD54

The ROM/VMB support certainly isn't "complete". The NCR5380 itself can do
SCSI for both disks and tapes.
My comparison point would probably be MFM emulator versus SCSI2SD v5.2. Documentation,
http://bitsavers.trailing-edge.com/components/ncr_symbios/scsi/NCR_SCSI_Eng…
, says the NCR538x didn't support synchronous SCSI until the 5386S. The SCSI devices
would have to avoid ID 0, as that's what the MV2000 ROM uses.
