Talking protect circuit

Hi Paul;
I wrote a long letter to you and somehow it got lost, so if you see 2 posts from me this is why.
First, try this, the two wires that go to the switch find the pins on the IC and Carefully bend them up, and attach another switch to them and connect the middle connector ground or to +5V depending on what it needs, I don't have a schematic in front of me. And see if the protect unprotect circuit works.
Also look around the traces that go from the switch to the IC and see if there is another trace shorted to it, unrelated to the protect circuit.
If there is no change them pull the wires to pins 20 and 70 and check them out using either a scope or a logic probe or a volt meter. And see if you can get them to show the proper values. If they work then either you have a problem in the Mother board or the memory board.
Thanks Marty
