Need Help On a PDP 11/60

Hi Everyone

I have some (3) PDP 11/60's that I'm trying to get running.
I did manage to get all of the Power supplies going, removed
all of the cards and cleaned them. check the cable routing
and power supply voltages. I have got the LA-01 and TE-10's
running. These systems have been setting since 1986.

I do have All zeros in the console display. No other console
lights come on ???? . no responce from any keyed input.

The Memory cards all have power LEDS turned on (m7984 Mos)
The Memory controller has a LED but it's off ?? (M7983)

These are from a large test system and each has 5 to 6 cabinets.
So in time I want to trim these down to the Base double wide corp.
cabinet only. It looks like the board label on top of each card
cage matches the cards. I believe the grant cards are all there
where needed. Most of the slots in the 2 main card cages are full.
The memory back plane does not have grant cards in the open slots
and from the manuals I have, this looks correct ??

The question for now is what do the LEDs on the M7878 (11/60 status card,
all on) and M7872 (11/60 micro word card, all but the top 3 are on)
stand for or tell you. I do not have any manuals on the cards and a
quick search did not turn up much.
 
I posted this yesterday and it did not show up so this is a second
post. so if you see 2 of these you know why.

 Yes, I might need help with my power bill also.


Thanks, Jerry
