how do I go about determining what EEPROM is equivalent? Is there
a decent reference guide for this sort of thing?
There isn't necessarily an EPROM equivalent for every PROM, and in
fact I don't believe there is one for the 8228...if your programmer
supports the 8228 PROM, though, it should be able to read it without
difficulty.

Yep. If there /is/ anything on either of those that
I'm missing,
let me know, but I swear I've looked.
So here's a semi-stupid question; having just acquired a Data I/O
EEPROM programmer which is also fairly adept at dumping EEPROMs,
is it possible to use the Data I/O to dump the VT100 rom in
question? That is, if I choose a PROM or EEPROM type that's
compatible with the type of ROM in use on the VT100 board, is it
likely that I'll be able to read it on the programmer like a
standard PROM/EEPROM? I'm kinda new at this particular corner of
the hardware field so I have no idea... can someone set me straight?
Absolutely...that's a pretty common use of such device programmers.
