decoding bad chip Apple IIc

[bibilit]

Anyone having some experience with bad chip location in the memory expansion board (Apple IIc) ?

MECC is detecting an error, so probably a bad chip, not a big deal but removing the board is a real pain as is lying under the keyboard and upside-down.

The Apple IIc is working fine most of the time, only not booting properly from time to time.

Problem solved, found the faulty chip.

Just a couple of questions:

Which Apple IIc was it? Is this some 3rd party diagnostic software, as I never seen it, only the Built-in ROM RAM Test on some IIc's have.

Which chip(s) was it? I remember Adrian Black on his Youtube Video fix an Iffy IIc with Bad RAM, the on ROM RAM Test gave out a binary code as to which chip was bad, BUT this code was in reverse to the chip location on the board. If the code was 1 0 0 0 0 0 0, the chip was on the extreme right of its bank.

IIRC MECC inspector as i am using it a lot. 

Was a chip on the auxiliary board.
