Does anyone know what address decoder chip(s), PALs, ROMs, and/or jumpers need to be changed on a PC7300 mother board when upgrading from 64K chips to 256K chips? I see only one jumper near the front of the machine, but I could be missing something. -- Bob Hoffman, N3CVL {allegra, bellcore, cadre, idis, psuvax1}!pitt!hoffman Pitt Computer Science hoffman%pitt@relay.cs.net

Apparently, at one point in time AT&T trained some dealers and VAR's on how to do the memory upgrade. There was even some documentation. Amperfax knows how to do it. Maybe some kind person can share this info. Dave Arnold UUCP: ...!seismo!uunet!arnold!dave
