[Techtoolslist] Fluke 9010a Troubleshooting w/ Omega Race

[John Robertson]

I'm beating up an Omega Race board right now for a customer and I 
find it is not very pod friendly.

I found that if one clipped pin 8 (9? - I'm at home right now) of the 
final reset stage and tied it high that this would deal with the 
negative RESET stuff.

I had a lot (8) of the 2114's that were bad and ended up making my 
Xeltek Super Pro be able to test those suckers as I do not have a 
stand-alone RAM tester that would handle the 2114.

Problems with reading the Vector ROM/RAM have yet to be solved, even 
had trouble reading the game ROM for a while - flaky 74LS138.

I hate getting working on these corroded boards. Not worth my time, 
yet too much of a challenge to discard...I love puzzles too much!
