Hi all,

I've a stock, un-upgraded 128K which is coming up with 040001 Sad Mac error immediately at startup (and slight graphic corruption).

From the following link, I believe this refers to a failed memory test "mod3 test", data bit 0, location F5:

... and that's about as far as my know-how goes Can anyone please tell me how I can now identify the faulty chip? In addition, the only other old Mac board I have is from 512K - any chance I can cannibalise a chip from this board?

Thanks a lot

JB
