I didn't get response to email either, so I called them, and they were very nice
folks. I think they have a weird email distribution protocol. -- Ian

Look 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.
Are they still in business? If so, perhaps they do not do it by email?
Numerous email to them from here have gone unanswered.
I'm another guy needing Unibus extender board(s) so if a group buy or
something similar comes together, add me to the list.

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?

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. :-)
