Does anyone have hex-height Unibus extender cards they would be willing
to part with, or loan?
We have created a printer interface card (based one the last rev of the
M8571 plus all relevant ECOs) for an LP20 in the front end of our Tops-10
system (a DECSYSTEM-2065). It turns out that the other cards in the LP20
are not entirely defect free, so we need to hook up a logic analyzer to
see where things are going wrong. We have no Unibus extenders, so we can't
do things like cool suspect delay pots.
We'd really prefer not to have to try building these. :-)

One has to wonder what a production run of cards might cost, and how
many people would be interested in them. I don't have any. :-( I'd
be more interested in dual and quad height. Hex height could be used
in a PDP-8 as well, couldn't they?

Look at:
http://www.douglas.com/hardware/pcbs/breadboards/digital.html at the
bottom of the page (for hex).
They will still build them for you, at $100 a pop as long as you order
10 or more.

Got it covered: I have some (that I bought from Douglas). The Douglas website can be a
bit hard to navigate, but the folks there are really nice. -- Ian

Are they still in business? If so, perhaps they do not do it by email?
Numerous email to them from here have gone unanswered.

something similar comes together, add me to the list.

I didn't get response to email either, so I called them, and they were very nice

OK. Roger that.
I was hoping to get them to offer some pictures of their various prototype
boards too as I am interested in those as well but find it hard to
visualize what the hole patterns and other routing really are on them.

Hex height would only work in a PDP-8/a. -- Ian

I used to use a dual and a quad for a hex when in the field. I have a
W9044 hex here you can borrow, but I think it is set up for VAX
boards. I have all the others, but they are still in storage.

My thanks to Zane Healy, Don North, Chris Elmquist, Paul Popelka, Dave
McGuire, and Paul Anderson, as well as to the two private responses I
received.
As it turns out, Ian (who's been out sick or lecturing at UWash for the
last week or so) had some in his personal collection, and dropped off a
couple at the office last night. (I had asked on the list because he
wasn't around when our colleague noted that he needed them to debug his
VM8571 and the other LP20 boards, so we had no idea he had them. :-)
