Hi All;
There Is a possibility that I have it Working..
I haven't put in any Memory yet, but I can put in a High Address and do a Load Address and it Responds..
I need to look up the Address for my M9312 and see IF it Recognizes it..
The Problem, seems to be a Pin that had a wire going and turning directions around a pin, and (I thinK) it had either worn thru or worn some of the insulation off of the wire and causing that pin to Read a LOW and for the Clock to work it needed to be a HIGH.. I moved the wire some and put an insulator on the pin.. Which means the Clock now is working..
I also, tied the four signals that were not getting to (A and B Unibus) slot 28 that needed to be there for that slot to work as a Unibus slot.. They were C0, C1, MSYN and SSYN.. These signals came from slots 16 and 21, which was the Bipolar Memory Controller slots.. And I don't have these Boards, So, I could Tie them to the slot 27 signal source.. Which also, may make it so My Core Memory Boards might work better, having these signals..
I have finally Found my old Power Supply that I used for the Core Boards, The +20 volts is good, and the +5 volts is good,
But the --5 volts is Shot.. So either I need to repair it or find another --5 volt module..
I found another Power Supply, like the old one, only this one works, in all three voltages..
THANK YOU Marty
