Groovy. So the ROM in question is a Signetics (I believe) 8228; how do
I go about determining what EEPROM is equivalent? Is there a decent
reference guide for this sort of thing?
The 8228 is a 1024x4 ROM. There is a standard character generator ROM
N82281-CB162 which has a pattern listed in a Signetics data book.
It's only 64 characters, upper case only in the standard ROM.
