I have seen the Shugart Optimem. It takes 1 Gbyte, and has a
SCSI-compatible port. Now, Emulex sells SCSI host adapters for
Unibus. Sothe hardware is there. But I think you'll have to
write your own driver (a pain under VMS, but under RSX I think
it could be worth the effort).
The ideal thing would be a transparent mix of a Winchester and
an optical disc. The Winchester would hold the bitmaps and pointers
. Deleted fields on the optical disc would then be marked as
bad spots.
