1) if the goal is to have an "authentic"
system, one has to have the
authentic EPROMs with the binary images in them. The spec's for programming
pre-32-pin eproms were not kept secret.
2) if the goal is simply to have a working system, there are several ways to
get around the ancient EPROM oddities. All of these involve wiring and
maybe even soldering something. The easiest of them, however, is to build
an adapter board with the binary images residing in battery backed rams
intended for substitution for EPROMs, and a simple programmer for them for
those situations when things go wrong.
3) Now comes the hard part . . . You have to choose.
Thats simple, if emulation will make you happy, why stop at the eproms,
just run one of the emulators for the whole system on your PC. My goal is
to get old systems running at a low cost, and I think that means original
or functional equivalent parts.
