I only have the S (well, there is a second one in the basement I need to
drag up). I did have one of those little 4 slot dual width boxes that
had a power supply but I sold it. Wouldn't help with quad width modules
anyway.
There's another BA23 down there, I'll probably try to haul it up next
Interesting. I have a Contemporary Cybernetics 8505 drive that I think
used the Exabyte tape system, will have to dig it out and see what it
looks like. Used them at the IEEE Computer Society for years but finally
went with IBM LTO tape libraries at Science. The LTOs were more reliable.

Thanks Noel,
Yes, I tried to repair an 11/34 once after somebody plugged a peripheral
board into a memory slot - I was doing well after 3 or 4 chip chnages,
it started to come to life, until I found the 20V went right into an
d=address line of an in-house numbered ROM!
Having been warned by
Not so lucky n Canada! They wanted $28 shipping!
So I got a box of 10 for $28 - but delivery end of Feb.
Back burner until then!
Thanks

You can still get boxes of sealed never used EXABYTE 112M 8mm data
tapes cheap. For example a quick search

I have this bit set that plugging a PMI card into a Q/Q slot will damage it?
(I think the issue is that some PMI pins are 12V on normal QBUS; too tired

Thank you Jim, John, and Glen.
I'll see if I can find one to tryout.
Good night,

Exabytes are pretty classic SCSi tape drives.

Off the shelf 8mm tape media works fine. Might not be "archival" rated,
but I have stuff that is 30 years old and reads

Unfortunately there is not a lot the on-board Dilog diagnostics can do.

I'm not sure if I have tried an
Thanks, Glen. I got out of direct field work around that time, and set
up a subsidiary of Emulex in Canada - so I was more concerned with sales
figures than buses. That makes perfect sense, I had forgotten about the
11/94. Funny how all my controllers are now Dilog, Plessey, and Sigma :-)

OK, thanks, Glen, i didn't think of that! Not sure why they would do

One thing I though of was just buying some IDC 36-pin card edge
connectors and wiring them together for the work bench!

Yes the BA11S would be too big. Can't see why not for the 11/03 chassis.
I used to make a good living upgrading 1/03 chasses with four extra bits
for the 11/23/73 (Hmm, where is my old stock of W933 bus strip!)
Always works except in the MINC laboratory system, which used those four
pins for
Hm. I have a 9 slot BA11-S that I have to sell/ebay/something here, but
that's probably way too big for you. I wonder though: Would an 11/93
explode if put in a traditional 18 bit 11/03 chassis? The one with the
memory refresh lines and power for core memory.
Probably.
