Ah, my bad, yeah, they do look like mini 50 pin scsi connectors.

It does have true scsi on it at least.. You say disks were "Not
officially supported".. I don't suppose they'd work still though?

(I've a number of varying size SCSI drives in external shoe boxes that
are easy enough to move around, and plug in. DSSI drives, well....
Unsurprisingly, I don't have any of those, should the below 3 turn out
to be boat anchors.)

I've poked around in it, and on the net enough to see what all is in
it.. Should anyone be interested..

2 RF72 1G drives.
1 RF31 380M drive.
TK70 Tape drive.
KZQSA SCSI Controller.
M7559 TQK70 Tape controller.
DELQA-SA Ethernet
CXA16-M 16 port ASYNC board.
L4000-AA KA670 CPU board.
L4001-BE 32Mb memory board (I still think that's a mighty large pile of
                                chips for just 32MB)

A DELNI "hub"
A DESTA thinnet adapter.
A H3104 for the CXA16 (So, only 8 of the CXA16 ports will be available.)

A C. Itoh CIT220+ terminal

I've not learned much about the juke box, other than its made by U.S.
Design, and has a HP C1718 MO drive in it.

And I believe all the necessary cables to wire it up.

That I'll have to check into..

Fortunately, I've already got a Encompass membership, and VAX/VMS 7.3.
(Is 32Mb really enough for 7.3?)

Putting it into working order will probably end up being a 2005 project
w/ my son and the holidays coming.

My thanks for the other suggestions/sites/warnings. I think I've got
enough to chew on for a bit..

Thanks all,

David
