Dead AIM ^%??

[Andy Dannelley]

Well, I tried the next steps, with my limited equipment, and no joy.

Here's what I've tried so far,

1. visually inspect - looks OK, nothing obvious like cracked or 
discolored components
2. check power supply - OK
3. check voltages on board - OK
4. remove extra ROMs
5. check clock with analog VOM - did not appear stuck high or low
6. check low addess lines with analog VOM - did not appear stuck high 
or low
7. remove all but low order RAM
8. swap RAM to try to find if bad zero page RAM - could all 8 RAM be 
bad?
9. feel parts for heat - nothing extraordinary, all appeared cool to 
touch

I have an offer of someone (he's got 6 AIMs)  I can mail it to, and he 
said he would look at it, but if there is something I can do here I 
would not have to impose on him.

Any more ideas, or have I reached the end of what I can do here?

BTW: I am not comfortable with de-soldering  and soldering, it's just 
been too many years.  I'm out of practice.

So let me know anything you think I can try (W/O solder) and I'll try.

Thanks again for such a wonderful response.

Later,
