[sdiy] EPROM has gone defected ?

[greg montalbano]

This has been discussed onlist before;  no consensus was ever reached.

I would suggest your best bet would be to simply remain subscribed to the 
list;  my experience has been that there's ALWAYS someone else onlist who 
has the file you need (I've supplied several & received several -- it works 
out very well).

As for the actual programming of the ROMs, same thing applies -- there are 
those of us with EPROM programmers scattered all over the place who are 
willing to program the blanks for just about any list member;  and, so far, 
a great many of the obsolete EPROMs are still available (& inexpensive) 
from places like JAMECO.
