Default Re: Nascom repair - Looking for clues please

IF the 6264 is a useful part here, I'm pretty sure that is the same basic 8k. X 8 memory IC used inside the Dallas DS1225 battery backed NVram, it's in there with a controller IC, these are easy to program and remember the data when removed from the socket. Also, in some applications, like Tek scopes, the Fram type FM16w08 can be substituted for the DS1225 and programmers like the GQ-4x will program an FM16w08 if it is set for a DS1225, recently the manufacturers of the GQ-4x updated the supported IC list in this point. So perhaps the FM16w08 could be of help too.
