Sorry,
Bruce never said a Quad4 memcal wouldn't work.  He said a 27c128 wouldn't (or
hasn't yet?) work.  I made the mistake of assuming the quad4 used a 27c128.


Anyway, now I think my second memcal has failed.  Now I'm getting "programmin
error" when I try to program it.  The damn thing wasn't erasing either.  I'd
put it in the UV eraser for 30 mins. and there would still be a few locations
not erasing, then I put it in for ANOTHER 30 mins. and it STILL wasn't
completely erased and then after ANOTHER 30, the programmer said it was erased
but wouldn't program it.
Looks like I'm goin to have to make a trip to the junkyard and grab a handfull
of these things.
