It may not be original equipment, but you could probably cobble up an
adapter to
let a UV-EPROM replace the OTP PROM device.
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?

Happy hunting.

I'm in search of a couple of blank 82S123s for
my recently-aquired
SuperElf boards. Who still carries such things?
Googling on 'blank 82s123' did not turn up anything promising.
Thanks,
