Eh? I don't have the manual with mine, but
2x27128 shouldn't be a problem,
I guess.

With the version 1 S/W you have to burn a copy of the system ROM first in
order to patch it and then burn the final version. Version 2 of the S/W has an
option (12) to copy the system ROM to RAM (if you have enough installed)
so you only need to burn one 27128.

I wasn't aware of these. Though I suppose I'd
still need an adapter, for the
programmer? I'll look for some data on them.

Not necessarily; the V2 S/W has provisions for user-defined EPROM
parameters, but I don't know offhand whether the hardware can accommodate
68754/6s (or 2532s for that matter).
