Is it _really_ SASI?  ISTR there's a 5380 chip in there, but I could
be thinking of the TK50Z-FA board.  I did once download and burn a set
of EPROMs to try to boot a (slow) SCSI disk in the MV2000, but I don't
think I ever got as far as loading a disk.  I have a 200MB 3.5"
Embedded SCSI drive ready to drop into a machine if I ever get a
chance to pick that project back up.  I know the interface won't be
fast, but it would allow me to use more modern disks, and that's
really, really handy, no matter how slow.

I think there is an NCR5380 in the VS2000 but I don't remember for sure.

However, I do know that I have used Wolfgang J. Moeller's PK2K SCSI drivers for
VS/MV2000 successfully to access directly connected SCSI disks on my VS2000 while
booted from either an RD54 or another cluster member. I have never tried replacing
the ROMs in order to be able to boot from a SCSI disk though.

(I have also formatted and used a number of random MFM disks pulled from PCs
on my VS2000.)
