IIe/IIc/IIgs
: roms?
: If not, what kind of eproms should I use to back up or
substitute them?

I know that IIe in the US are 2764 for CD and EF,
2716 for Video ROM and KeyBoard ROM, but the Euro
models are 2732 for Video ROM as they are dual-
language. The Platinum //e has CF rom which would
be 27128.

The ROM-FF or original IIc ROM is 27128, and ROM00
through ROM04 take 27256. I assume that Video and
Keyboard ROMs follow the IIe US standard since they
weren't marketed in other countries.

The IIgs I am not sure about, I've heard they are
eprom compatible from one source and not compatible
from other sources, so I won't claim either now.
