Does yours look like this:

The one pictured should be from QZ which had PDP-10 machines.

Exactly. See:

So which class of pdp-10 did QZ have? KA or KI?

I know for certain they had KL and KS machines but no KA.
It is possible they had a KI machine.

Ok, then my guess is this either came from a KI or a KA with a very
different memory box. I'll put it in the collection, and oddly enough
I'll bet that it could work in the 11/05 if one of those boards ever
blow out.

I have not seen a cover but how about an empty header shell. I forget if
they're called C-Grid but it's the ones you have to crimp pins and insert into
the shell. I have those "in stock" but usually not bigger than 2x13, but if I
wanted to protect something, that's what I'd grab off my shelf.

I've cut the stuff six ways to Sunday and I've never had the problem of

that's a thought, thanks. This is 2x3. That could work.
I may end up just clipping off the pins!

I guess it's as cheap as you can get. :)

Interesting. I went up to the attic and opened the Unibus box. I have 3
extra 11/24 boards, and I have *NO* idea why. Oi. So anyway I started
popping them into the 11/24 chassis to see what happens. Run/halt in

Hm. Even odder: When I went back to the original CPU board and changed
the switch settings to that of the working board I got garbage on the
VT100. Checking with a PC and PUTTY I see it *is* now working but at
19200 baud even though I have it set to 9600 baud...

Why couldn't you get a piece of #20 wire and strip off an inch or so. Bend
it into a U to block out two pins.
It might need #18 or #22 but you get the idea.
