Very Computer

  Found a strange card recently:

Practical Peripherals GraphiCard 2086
- 6 position dip siwtch at the top middle of the card
- 20 pin header connector at the back (no cable though :( )
- Made in USA, Copyright 1983
- PN: A1002100 Rev B

  Anyone have any idea what it is or any information for me on it?

                        Thanks
                                Tim

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
