That is probably the way to go. The Ethernet controller has direct DMA access
to the entire 16MB of memory supported by the VS2000 (I suspect the driver,
however, works with a ring bilt in a reserved region of memory because that's
how it's done on other LANCE designs; haven't looked at the driver yet).

The drive supported by DEC is the SCSI version of the TK50. Rumor has it
that there is a difference between the model shipped with the VS2000 and the
model shipped with later SCSI systems (I've not investigated, but I suspect
the version originally shipped with the VS2000 doesn't disconnect).

I have not tried other tape drives, such as an Exabyte, with the 2000. The
TK50 is, IIRC, set to respond as unit 1 for the VS2000. It's normally jumpered
for unit 5 in other systems.
