Re: Flakey ZipChip 8000

with these things to get around contact problems?  Is there life after broken
pins?

I can almost imagine a circuit board with a pair of 20-pin headers and 40
holes offset a bit so I can solder the ZipChip on permanently.


I had foreseen this on my Zip chips and on Accelerators for the GS. I
desoldered the CPU socket and installed a ZIF socket on both my IIe
and IIgs motherboards.
Excellent plan! I'll order up a couple of 40-pin low-profile ZIF sockets forthwith.
If I break a pin off, it's at least feasible to grind away some of the potting material and solder a lead on.
The startup problem appears related to reset. Turns out it's not pressure that makes it boot - it's capacitive coupling of my hand! Wierd.
