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). | 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 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.
