I've done this, programming ISD chips using edge connections, plugged into a
card-edge connector. Just picked up sufficient of the connections for my needs,
left the others blank. PCB had to be carefully positioned, I aligned with one
end, to avoid cross connections.

It needed care but worked fine. Programmed many dozens this way, it's what I'd
do for a few hundred off.
