Tektronix 5000 series oscilloscope mainframes have three plug-in slots; Two vertical and one horizontal.

The interconnect on each slot type is a 56-pin PCB edge connector with 5/32" pitch.

Looking into the mainframe from the front panel, "A" pins are left of the connector centerline and "B" are on the right. Pins are numbered from 1 at the bottom to 28 on the top.

The table below shows the connections as if looking into the mainframe from the front.
