I can't find a good reference for what the ribbon cables should be
connected to in order to just run an A-155 Trigger Sequencer (no A-154).

Is there a good reference somewhere or could someone tell me exactly
what kind of ribbon cable plugs into what socket to run just an A-155?

 Someone I've been e-mailing just got a used one from Analogue Haven
and we both think it's missing the original power cable. But asking
the question made me remember I  think I tried to follow the steps for
installing an A-154 in reverse but they just weren't very clear when
followed backwards what I should wind up with.

thanks!
