Carl Holzmann emailed me a circuit diagram of a 37 pole connector 
with 8 switches for a LCX. You can download it from 
http://www.lanbox.com/downloads/downloads.html#other

Thanks Carl!

Yes, but only for next/pre step (not cue). There are many solutions, 
but below is just one:


// Cuelist 150 (11 steps), stored 18-04-2006 14:05
001:
  hold for 0.05s
  go 003 if input 1 within 512 - max // jump if switch 1 is not closed
  go next in layer A
002:
  hold for 0.05s
  go 002 if input 1 within 0 - 512  // wait until switch 1 is released
  --
003:
  go 001 if input 2 within 512 - max // jump if switch 2 is not closed
  go prev in layer A
004:
  hold for 0.05s
  go 004 if input 2 within 0 - 512  // wait until switch 2 is released
  go 001


Run this control cue in any layer other then A, and the switches 
(buttons) will do nex/prev any cue running in layer A.
