Or at least push the chips back into the sockets! Back on my TRS-80 (the good ole days :-) Model I, of course!) the BASIC ROMs were on the underneath the keyboard and gravity would tend to pull them out over time. The interesting thing about it was that the major symptom was the builtin functions (eg: CHR$()) acted like they were arrays of DIMension 10 (the default without an explicit DIM statement) instead of functions. Other than that (if I recall it correctly), the machine acted fine. >Was there ever any real field-proof that gold-edge contacts are >better than <x>-edged contacts?

I still have a hard time believing in that, considering that the gold came off by merely connecting the connectors. >first things the support tech said to do was clean all of the >card edges with an eraser. Reminds me of the time that we were visiting one of the Plato labs down at the U of Illinois. The Avatar players, er, uh, I mean STUDENTS :-) were complaining that all of the terminals in the room were acting wierd. We opened the connector box, and found half an inch (no exaggeration) of dust on the connectors. It amazed me that the terminals worked at all! The "new" sticker on one of the boards in the box gave us a chuckle, too. -- NEVIN ":-)" LIBER ne...@igloo.scum.com or ..!gargoyle!igloo!nevin (708) 831-FLYS Advertisement: Hire me!
