Tektronix 5000 series oscilloscope mainframes have two vertical plug-in slots, and one horizontal plug-in slots.
The interconnect on either slot type is a 56-pin PCB edge connector.
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.
