4–ROMs may be masked to use what would be address lines on
eproms as chip select lines. This means that they would address or
enable the part in a low condition instead of a high condition as with
an address line. This means that sections of the data might be swapped
as you read it. It could also mean that the part has no eprom equivalent!
5–The QuickPulse algorithm is not for all brands of eproms. If you are
having trouble programming a part with QuickPulse, try using the
intelligent algorithm (if that algorithm is available for the part– TI). A
good example of this is the GI part 27C256. It programs fine with the
intelligent algorithm, but not with the QuickPulse algorithm. Type “TI”
to select the intelligent algorithm for this part when the “MZ” command
is issued. (MZTI)
