Mechanically, the interface is a direct card-edge connector with 28 contacts on either side (numbered from 1 at the bottom to 28 on the top) at 5/32" (~0.156" or 3.96 mm) spacing.  The connector can be keyed in several places, the plug-in boards have matching cuts between contacts (see below).

There are two dedicated, floating 25 V<sub>AC</sub> transformer windings per slot, as well as several AC and DC buses shared by all slots.<br />
The mainframe provides supplies shared by all slots: 17.5 V<sub>AC</sub>, +11.5 V (regulated from the 17.5 V<sub>AC</sub> supply), +33.5 V, and −33.5 V. 
For each slot, two uncommitted transistors (one NPN and one PNP) are mounted in the mainframe. These are available for the module's power regulation circuits.
In addition, there are two dedicated, 25 V<sub>AC</sub>, 0.5 A transformer windings per slot, floating up to 350 V<sub>peak</sub> with reference to the common ground..
 
In mainframes that have a "high-power compartment", that slot has a separate 17.5 V<sub>AC</sub> and 11.5 V<sub>DC</sub> section providing 4 A shared between them, and that slot's 25 V windings are rated 1 A each.
 
For each slot, two uncommitted transistors (one NPN and one PNP) are heatsink-mounted in the mainframe. These are available for the module's power regulation circuits and are rated to dissipate 7.5 W each.


The signal pin connections depend on the individual modules.  For details, please see the [[Media:070-2088-00.pdf|TM 500 Rear Interface Data Book]].
