I guess I'll post this to tech-talk, others may be interested ...

The XYCOM 566 drivers determine what input mode you selected by expecting the
following addresses ...

    XYCOM MODE        CSR Addr      Data RAM Addr

  Single ended       A16: 0x6000    A24: 0x000000   (card 0)
   (scanned)         A16: 0x6400    A24: 0x010000   (card 1)
                          etc

  Differential       A16: 0x7000    A24: 0x040000   (card 0)
    (scanned)        A16: 0x7400    A24: 0x050000   (card 1)
                          etc

  Differential       A16: 0xe000    A24: 0x0c0000   (card 0)
  (Latched,requires  A16: 0xe400    A24: 0x0d0000   (card 1)
  a ext trigger)          etc

  Waveform Mode      A16: 0x9000    A24: 0x080000   (card 0)
   (Waveform         A16: 0x9400    A24: 0x090000   (card 1) 
    Record)            etc

  The Device Type selected in DCT (SE Scanned, Dif Scanned, Dif Latched) must
match the way you addressed the card. Four cards are supported for each
type. "Signal" goes from 0 to 15  (differential) or 0-31 (SE). Parameter is
ignored.

  Interrupt Level 5 will work (I believe). 

  The input jumpers for each type are a real challenge and left as an 
exercise for the user (I don't have a board handy, sorry). However, the
above info will stop you from having to grep through modules_types.h, like
some of us have had to do !!

One more thing ... Don't blame me, I didn't write it !!!!
