Mechanically, the main 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).  An additional 20-contact card edge connector carries the [[GPIB]] signals.
