Thanks you for all your help, After I took another look at the insides of this thing, I
realized there had to be somewhere to plug the 3rd connector on the ribbon cable, and I
found it, the keypad display board. and then I went and reseated(very carefully) all the
proms that needed it, turned it on while holding down the store button and after
autocalibrating, it was alive!!

Yes I am relieived now Thanks everybody!
