Thanks for the couple of suggestions. I should have been more clear on my original question. I'm just trying to read the PROM (it is a PROM isn't it?) to verify against the MAME set that it's not corrupted. I'm using an EETools Top Max which is a pretty good device (although it can't do the 2708's). In the past, Al Kossow's original PROM cross reference (now hosted on a few sites, but I usually pull it from mikesarcade.com) has always been able to stear me to a substitue PROM to be able to read it, but this one isn't listed.
I know what you mean - I made my own enquiries into this in the hope that my Data I/O 29B would handle it, trouble is that it won't even read the 82S153 without the UniPak. :( Unless anyone here knows differently? _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
