Does anyone know of a modern connector that will substitute for a real
DEC connector? The H-11 used a different one for its Q-bus backplane,
for example. I am attempting to make a replacement H851 (well, over
a dozen, really) so I can restore a PDP-8/e (three core stacks plus an
RK8E I just received).
In case anyone who knows connectors doesn't know the DEC specs - the pins
are on 0.125" centers and the edge connector is somewhat taller than, say
an ISA connector or a 5.25" floppy edge connector (it's 0.625", but the
Heath connector does not accept the entire length)

Also, a
quickie question: how many pins are on the Unibus?
Each DEC edge connector has 36 pins (18 a side, 2 sides).
