The Exeter 770 I recently acquired had the MIDI coupler tabs on the stop rail
but the piggy-back MIDI PCB had not been installed nor was there a connector
panel under the keyboards. That said, all the note on/off and stop tab data
are collected by parallel-in, serial-out shift registers on the CPU and
auxiliary board next to it, and the swell and crescendo potentiometer positions
are converted to parallel digital form, so all we have to do is find a
programmable MIDI encoder that will accept digital, logic-level signals that
the shift registers feed to the microprocessor at compatible clock rates and
we're there! Simple, eh?
