Totally amazing. This might be from an old enough vintage that there are similar documents. Also, if there is a controller module in the rack, it may be possible to remove it, solder some wires to the back of that module's connector, and take over the control of the rack. The protocol at that level is probably dirt simple, like one wire to each slot to select it, a digital bus of however many I/O pins are on each module, and a read and write strobe. You could probably get a BeagleBone to control it very easily, then you just need some protocol to remote the I/O functions to it.
