FYI, in my 750, the UNIBUS expansion has a L0010 in the main cabinet and
a M9014 in the expansion cabinet. I didn't note the details of the
cable(s) between the two when I did the inventory of my system.
On another topic, we had discussed me going through my B1000 stuff and
Burroughs contacts

Interesting. I can't think of a reason why the two ends would need to be
different, but otherwise why do both exist? I've seen M9014s only

From: tony duell
a 'Unibus Out', you can plug a Unibus cable in there to link to an
expansion box. The official way involved special dual-height cards at
each end with 3 40-way Berg-type cables linking them.
So I'm trying to look into this (BC11 cables being unobtainium these
So I'm trying to look into this (BC11 cables being unobtainium these days, at
least at prices which are less their weight in gold).
Are they really that rare? I've got a small box of them here.
I assume the M9014/M9015 are a pair, one used at the start of the cable, and
one at the end?

The reason you'd want a button to disable the board is when running
diagnostics, you can remove all the non-DEC memory without
physically removing it.

I thought of throwing that idea out there, but having lived through the great
RAM famine the thought of a spare
RAM chip seemed kind of silly. Incidentally, the RAMs are all soldered on my
Camintonn boards.
All the RAMs (but not the buffers) on the NatSemi boards are in sockets. And I
