PDP 8/e memory boards

I'm trying to get my 8/E working. I've installed a basic set of boards: M8330 M8310 M8300 (with jumpers to the previous board) M837 memory extension M849 RFI shield <memory> M8320 bus loads Well, first off, the extended address load switch seems to be broken, so I cant access extended memory (maybe I should yank the M837 board for now). I tried a few core memory sets, but I dont think they are working properly, or possibly they arent configured properly. The memory sense/inhibit boards have jumpers for selecting the memory field, I'm guessing you have to start at field 0 and increment in continuous fields? What about 8K boards, do you have an 8K at field 0, and an 8k at field 2, and the boards would be covering fields 0 - 3? Is EMA 0 the high or low bit on the field selector jumpers (on the memory sense/inhibit boards)? Whats kinda confusing me is that I have a pair of 8K core memory sets that came from one computer a LONG time ago, yet they are configured for fields 1 and 2, whereas I think they should be 0 and 2. I also have a 16K core set, does anyone have any information on that board? The highgate docs appear to be for a hex wide 16k board. I think the majority of lights on this computer are burned out, leaving about 8 bulbs working. Is there any way to verify that using front panel controls and no memory? -Lawrence LeMay
