Re: Zip chip on a IIc

[buggie@callisto.unm.edu (stephen e buggie)]

My "flagship IIC" has an AE ZRAM ULTRA 3 and a ZIP-8 chip.  Both work great.

I write to suggest that if you are moving you ZIP chip in and out of the 
socket, you are then weakinging its forty legs.

To save it from breaking a leg during all this movement, install the Zip 
chip in a "carrier", another socket.

JAMECO even has a 40-pin ZIF (zero insertion force) socket --- expensive 
(about $8) but worth it if you are moving such a valuable chip around...
