I can get 28/56 pin connectors (~$4 each) and cut them down - I'm looking
at a Sullins EZA28DCSN. Given that I'm attempting to replicate a DEC H851,
I suppose I could cut two down to size, but put them on a PCB with the cut
edges on opposite sides, providing for _some_ sort of left-right registration
integrity. The PCB would be about 2.5" by 1" with 72 holes. Depending on
quantity, they might be <$10 for double-sided with plated-through holes.
A single-sided version I could do at home on a prototype run (never tried
to burn double-sided boards at home).
This is a perfect example of why it's better buy than make electronic bits.

Sullins has a 50/100 0.125" connector in a high-profile (0.265" insertion
depth) - EZA50DCSD You could cut _that_ down.
Anyone know of any other 0.125" edge connector manufacturers?

No idea.
