Tim,

It's a printer interface for an Apple ][+, //e.  It supports various 
modes to print the Apple graphics and //e 80 column screens.  

The DIP switch selects the type of printer you have connected (only 
switches one through four are used:

Printer:	1	2	3	4
Epson		On	On	On	On
NEC		Off	On	On	On
Anadex		On	Off	On	On
IDS		Off	Off	On	On
Oki.84		On	On	Off	On
Oki.		Off	On	Off	On
AppleDM		On	Off	Off	On
Mann. Talley	Off	Off	Off	On
BMC		On	On	On	Off

The 20 pin connector is for a standard Centronics interface.  The pinouts 
are:
Pin	Function
1	Strobe
2-9	Data-0 through Data-7 respectively
10	Acknowledge
11-20	Ground

There is also a whole raft of commands that can be imbedded in the print 
stream to format the output (landscape/portrait, formatted BASIC 
listings, etc.)  If you want them let me know and I'll see if I can find 
time to type them in.

be seeing you ... Don
