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

Subject: Re: Unibus extender cards
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.

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?

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. :-)
