Hello,
I have programmed some PAL's, GALs and FPGAs a long time ago. I am trying to verify all the EPROMs on the Main board of my operation wolf. First thing is I don't recognize this "I" manufacturer. I think, I just found a 27512 in one of my lists maybe under atmel. I ran a checksum on it. And got a hex value of "00FF0000" so here are my first couple of dumbass questions:
Who is the manufacturer of this chip?
Second question: I have MAME rom files....9 files. So how do I know which EPROM gets which ROM image? I understand that the checksums need to match, but if you have a bad EPROM that gives a goofy checksum, how do you know which MAME file to load to the buffer to reprogram the bad EPROM?
Any Help would be much appreciated.
