Question for any Vax wizards hanging about:
I just received a VAX 4000/600A in a BA400 rack mount chassis.
It contains no disk. I'm having a little trouble sorting out part
numbers and abbreviations online, but I think I'm looking for one or
two RF72 or RF73 DSSI disks in ISE packages.
If I'm barking up the wrong tree, cluestick whacks to tell me why
this is a bad idea or impossible to find/maintain, or what I should
try instead, would be appreciated.
The box does have a KZQSA controller, but I like the neatness of the
ISE modules.
Thanks,
De

If I'm not mistaken, ISE (=Integrated Storage Element) for DSSI just means
"disk", and it may be cabled internally, IE with ribbon. There are ID
selectors that go on the disk _housings_, but they may be skipped and
overridden with an on-disk jumper block, at least with most RF series.
Any DSSI disk should work The RF31 starts at under 400MB, the RF74
ends at under 4G. DSSI disks are getting rare, but are still do-able on
eBay. I've got some too.
Good Luck,
John A.

This mass storage bay of this cabinet has a backplane full of somewhat
centronics-like connectors. The carriers can hold one 5.25" full
height drive, or a pair of 3.5" drives, and have extrusions to hold
them into the card slots in the bay. They also have the ID plug
sockets in the front of them, as you describe.
If I can find the carriers, it'd be nice: lots neater, less tracking
down of cables and reengineering the inside of the cabinet.

I heard from somebody (might be Ethan Dicks) that you if you had SCSI
controllers, you could make some small changes to the wiring and then
install SCSI disks in those bays. The connectors have 50 pins -- same
as those used with SCSI disks.
