Programming Delco EPROM's.

[DC Smith]

I never have had much luck programming the original delco chips from
the 7148 boxes. Maybe once in a while I may get one to take. (if I try
about 10) I don't know what chip to use, but usually set my ROMMAX up
with the generic 2732A algorythym. Sometimes it works, sometimes not.
 I have my best luck just pitching the delco chips and using the Intel
2732A's . They even self ident in my programmer, where as most other
chips will not.

 Good luck!
