I have an IBM PC with a SixPackPlus in it.

Features:

- memory expansion upgradeable to the maximum addressable user memory 
  in the IBM PC, PC-XT, Portable PC, and 3270 PC systems.
- Real-time Clock-Calendar with battery backup.
- RS-232 asynchronous serial communications port.
- parallel printer port.
- optional game adapter port.

Clock:

 To read/set the clock, you'll need ASTCLOCK.COM, the real-time,
 clock-calendar program.  Should be put in your autoexec.bat file.
 You can get it through AST's BBS in CA.  There's also a bunch of
 utility programs which I think you can also get from their BBS (I
 don't have them).

Now on to the switch settings...

Position 7 of switch 1 can be on or off

Parity check:   s-8 on  = parity enabled
                s-8 off = parity disabled


Remeber to replace the lithium battery if dead.  This'll get you going.
The AST BBS in CA has more information or you may send for a manual ($$$
I guess).
