Self-test IIC: Which RAM chip is bad?

[buggie@ben14.unm.edu (stephen e buggie)]

Someone shipped me his IIc motherboard for repair.  First, I ENHANCED it
with a BUGG-ROM --- Bugg-Rom adds the checkerboard self-test.

When I activated the self-test, this error message popped up:

        * RAM    ZP  0 1 0 0 0 0 0 0 0 

I know from the   *  asterisk that the bad RAM chip is in the upper bank
--- the 8 RAM chips that are furthest back.   But which RAM specifically
is bad???

Also, what does the "ZP" mean????

I knew the answers long ago, but its been a loooong time since I last
replaced IIC ram chips.

The replacements will be socket-ized, of course.	Steve Buggie
