[sdiy] Nasty Bits in EPROM

[Rob]

Anyone ever have a UV EPROM that just will NOT erase completely? I always
seem to have a bit that says FB, but its not at the same address every time.
I dled the rom image and did a search, and I find FB in 2-3 places, but
after UVing them, the addresses change!!

In all the hundreds of eproms I have UVd, then reprogged, then UVd again
over and over, I have never in all the thousands found one do this.

Arrgh!! I hate when stupid things like this happen..
