BTW: stating "PROM's are EPROM's" would be in error - similar to the error you are making in conjunction with firmware and software.
Still trying to figure out why you included "[sic]" - are you claiming EPROM is not spelled EPROM or PROM is not spelled PROM or do you not like the "'s" for plural? You might want to do some searching around - that is a very common way of showing a plural state. I think you are just blindly striking out - trying to find something to attack.
Firmware and software at least have a relation, since firmware is what you call software in certain settings. We had a discussion about the semantics and definitions of firmware/software, which as you've noticed even differs depending on source.
But stating a PROM is an EPROM is just ignorant. PROMs and EPROMs are completely different things. A ROM is mask-based, a PROM is fuse-based, and an EPROM is capacitor-based. PROMs are written using a current since you're trying to blow fuses, and they are digital because a fuse is either blown or not blown (0 or 1). EPROMs are written using a voltage to discharge the capacitors, and are more analog because there can be varying degrees of charges left in the capacitors, the 1s and 0s determined based on a threshold amount of charge sensed.
They are so absolutely different that anyone who knows what he's talking about couldn't state that. .

Now wait one minizzle. Ebonics is a perfectly acceptable way of communicating in some circles, too, but I wouldn't go so far as to say it's correct either. An' dat's da fo one one, know wha' ahm sayin', beeeeyatch?
In the arena of "finding something to attack," you are the 2005 Poster Boy of the phrase "target rich environment."
