[Techtoolslist] Help troubleshooting a 9010A

[barry2 at shilmover.com]

Hooked up the 2nd 9010A.  It returns:

R/W ERR @ C000 BTS 12 - LOOP?

I been having trouble posting to the group...  trying again.

I have 2 non-working 9010A units.  On both they beep once, LEDs flash, then 
nothing.

Hooked up a working 9010A that I borrowed (thanks David).  Bus tests fine.  RAM 
returns the following:

R/W ERR @ C000 BTS 08 - LOOP?

Manual states:
If a RAM failure occurs, carefully examine the diagnostic message.  The RAM 
Test is usually sufficient for deducing the failed component directly.

It then does not explain how to read the message.  :-)  I am new to this, so be 
kind if its a stupid question.

I deduced that there is a Read/Write error at C000.  How do I "deduce" the 
failed component?
