Hi,
I've been thinking about much the same thing... the device ID's
of each SCSI controller on the link need to be different, so linking
two SCSI-B bus together won't work without changing at least one.
I'm not sure if these are jumper settable on the board, but would
guess it may be a simple h/w hack if they 're not.
Initially linking to a pc may be easier since pc SCSI controller
device ids are often switchable.

out ports are the same as in ports :). But there is quite a length of
cable inside a VS3100 so rewiring direct would probably be needed to keep the
bus in spec over 8 machines.
As for the "special" connector, if the connector is on a 50 way cable
you can probably just cut it of and crimp on a std 50pin one from an
electronics store.

Yep they must be there, should be easy to identify, and whip out.
