eproms

[Mike Rolica]

OK, so I have a 87 165 ecm with a 27c128 eprom.  Now a couple of questions.
Can I huse a 27c512 eprom cause it has extra room?  What would I have to do
to use this one and/ or why can't I?  Second I have asked this question
before... but can I use a eeprom instead (so I don't have to erase it uv all
the time) ?
Lastly  where would I find some blank eproms ?
