Well, i can only give you the figures i know, hope these help

DEC mentions DSSI disks and SCSI tape drive and CD-ROM as primary
storage

It only has one DSSI adapter build in, so you can connect 7 devices

It's a normal DSSI (SHAC 1200 I/O's per second) adapter: TF85 is
supported, but only in a DSSI storage expander.

Since it's a cabinet like a 3100 model 80 you can not add more than 3
3.5-inch DSSI disk drives (RF31T or RF35) drives in the system
enclosure.

Open-VMS V 5.5-2

The 4000-100 has a "Q-bus capability": it's possible to connect the
system to a Q-bus VAX enclosure, and add Q-bus controllers (DSSI, SCSI,
even SDI :-). The system itself does not have a Q-bus!

Pay attention to the performance: it's a 24VUP (almost 5 times the speed
of a 4000-200 at appr. the same price!) machine with a maximum of
128Mb main memory (DSIM) with fast ethernet (SGEC) and can be clustered
by DSSI!
