Why wouldn't a 27C64 work? (admittedly, I
don't have the data sheet
in front of me). You'd have to make a pin swabber for the destination
machine, but electrically, it's a "C" part, not an "HCT", so
I'd
expect it to work at 10V, but the datasheet will say for sure.
The fact that there is a "C" in the part number does mean that
it's
implemented using *a* CMOS process, but it does not mean that it is a
CD4000B-compatible CMOS process. The electrical specifications are in
fact more similar to 74HCT than CD4000B.
None of the common EPROMs, EEPROMs, or flash memory parts are rated for
operation above 6V (and most not above 5.5V, and the most recent ones
not above 3.6V), even if they have a "C" in the part number.
