Remember everyone that John has a ST-8000A which is the USAF version  
of the ST-8000
The two are VERY different.

There is another alternative.

If you remove the cover of the ST-8000, you will find jumpers inside
with one end hooked to the expensive plugs / sockets and the other
end connected to the electronics with a much more common inline plug
that is readily available from Mouser and inexpensive.  I just mad up
some new cables with screw type terminal strips for the external
connections.

I have a ST-8000A and, with information from Bill
Henry, came to an "easy" and clean solution. My unit
has an unused panel hole and cover plate next to the
normal, but expensive connector.

I found a Canon panel connector of the correct
physical size (the four mounting holes line up, so no
drilling) and a mating cable connector in my junque
box. Connections to the PC board inside are made with
IDCs (insulation displacement connectors) on the
board's header pins, so you can simply buy the right
size IDCs and run wires from the IDCs to the new panel
connector.

Of course, you will have to have some information
about the pinout of the expensive connector and trace
the wires to the existing IDCs on the board.
