PDP-11/34a hung bus problem.

A little progress on the 11/34a I have a PMK05 (Unibus exerciser) of which I forgot I had it..... I checked it out first and noticed that the aluminum casting around the 4 slot backplane was broken on both sides. After repairing it by making 2 sleeves of thin copper sheet and a cobblers hammer it became strong enough to insert the cards again. After hooking up the PMK05 to the unibus, the machine was powered up with the memory card, and the 'NPG' led was on. When done without the memory card, the NPG led stayed off, and others came on. The address & data leds changed after depositing a character in the transmit buffer of the DL11-W. Pics at www.groenenberg.net/download/PDP11/pic for thos who want to see the PMK05 in action. (BTW, the unibus in and out are misprinted on the silkscreen and are reversed). BTW2, is there someone who has a manual for it? I only have 2 (xeroxed) pages of information.
