RE: Re[2]: VECTOR:Update on my latest Endeavors to Fix my STAR WA RS MAINBoard.

Peter,
******

 Will proceed, as you suggested and check out Resistor Pack PR-96
I would like to ask you though, what the Value(s) of this Resistor Pack
should be ??? so I know what to expect.

 Also will Replace the Chip in Location 8M (LS138) which as you stated
resets the IRQ line, then report back.

 Arcadius.................

YOU ARE CLOSE!

2M (LS74) PINS 10,12 ARE CONNECTED TO PR96
i suspect that this is a sil array, find the resistor-pack PR96 and check
it,

replace 8M (LS138) it resets the IRQ line.

GETTING SO CLOSE NOW, YOU CAN ALMOST SMELL THE BURNT SILICON! :-)
