I've got a really dumb question that's probably got a simple answer. I've
tried searching for information here regarding the topic, but I can't find
anyone else posing the question. So please forgive me if it's been answered
or obvious to everyone else:
Why does the N8VEM need to use an EPROM, are there no suitable EEPROMS?
It just seems like the convienience of using an EEPROM would be worth the
extra effort. But I could be flat out wrong in my assumption.
In my research it's obvious that there doesn't seem to be a pin-compatible
EEPROM that could replace the N8VEM's 32-pin 1M x 8 EPROM DIP. Availability
or the existance of a 1M x 8 EEPROM seems the only obvious answer I've been
able to piece together.
I've also considered that there may be a cost concern. If that's the case
are we talking the difference between a ~$9 EPROM vs a $20 EEPROM? Maybe
it's more like a $50 EEPROM replacement? Then I could also see this being a
decent reason.
Anyway, it just seemed like a question that hasn't been so publicly
discussed. I'd like to see if the community has pondered this as well.
