Talking 1K ststic

Hi Benalford;
I checked the Schematics, and you were right on one and wrong on the other, and the jumper I'll have to check on... On the Transistor you are right, and on IC K you are wrong, a closer inspection of the Schematic shows that pin 12 IS tied to ground, and pin 11 and pin 2 are tied together before being pulled up, by a resistor... I have an Origional Altair CPU Board and I compared the two for both IC K and the Transistor circuitry,,, they are the same... So I suspect that they changed the transistor circuitry when it didn't work and forgot to change the Schematic or they changed the schematic and never got around to doing the board...
THANK YOU Marty
