Er, no. EPROMs won't work. These are the same Bi-Polar PROMs used in the
HP 1000s and I thought of trying to use EPROMS too but EPROMS are too large
and much too slow and have an entirely different pinout. I'm also finding
that the PDP-8s use the same (or VERY similar) BiPolar PROMs.
Perhaps we should consider a group purchase of a batch of blank BiPolar
PROMS?
