The "other one" is California Computer Systems (CCS) Model 7710
Asyncronous Serial Interface.  The DIP switches are for setting the baud
rate.  Here's a table for the usual baud rates.  A 1 is for On (up); the 0
is for Off (down).
     Baud  Switch
     Rate   1234
     ----   ----
     19200  0111
      9600  1110
      2400  0001 or
      2400  1100
      1200  0010
 
I don't know about the Apple card you describe.  Good luck.
