My Antique Mac has developed a fibrillated clock. It jumps to random other
era's, or dies completely February 6, 1940 at 6:28:15 AM.
I took the CPU board out, and ran the computer while watching and waiting
for this to reoccur.
The chip stops dead... This could be the $0.39 crystal, but I
suspect it's probably the clock chip itself.
The problem is I can't identify it, let alone find a source for it.
It's a little 8 pin with the numbers 8504 on it, but that looks suspiciously
like a date code to me.
Does anyone know what this chip is, and hopefully, where I could get one?
Thanks,
jim
