Thank you all for quick answers!
For better understanding. I want to connect the TU56 to my PDP8/E with a
TD8-E controller.
In the transport maintenence manual i found that the G742 is the
Positive Logic Jumper Card. I think is for a positiv control bus, and
the M531 is used for the negativ logic controller. I have the G742.
@Pontus: Thanks for info. I will do so.

Hello ClassicCMP`s
I`am resorating an TU56 dual drive. It is clean now, i repaired the powersupply, i
formated the capacitors and i checked if all modules that needed are existing.
My question before first "smoke test" is done is....
In the engeneering drawings "Module Utilization" are shown special places for
each module. In my drive the Modules on different places then in the drawing.
Is the backplane a real bussystem or got i use the ports shown in drawings?
The
?backplane? is the wiring between the modules. It?s the equivalent of the wires on a
printed circuit board interconnecting the chips ? with the modules as ?chip? and the wire
wrap connections in place of etched wires. Moving modules around is like switching chips
around a PCB ? in general, you can?t do that. So you need to find the correct placement
for the backplane you have. Perhaps the drawings show the backplane wiring explicitly.
If not, then it should be implied by which signal goes from one module to another. You
may need to pick some signals on the drawings and trace them on the backplane (follow the
wire from one connector to the other) to verify that your current module placement is
correct.
