Apple IIc 'Real World Interface'?

[macgyver@tartarus.uwa.edu.au (Antony Lord)]

Recently I have been toying with real world interfaces for computers :

I have built several for a C64 (with its 8 channel I/O user port)

I have designs for RS232C devices that work with PC's so I have set about 
asking questions on how to go between RS232C and RS422 (the printer / 
modem socket on a Mac.)

Inbetween all of this I have my trusty Apple IIc sitting on the desk. I 
have little idea how I could interface anything in terms of output to it.

Does anyone have schematics or pin wiring diagrams? I have looked for 
various RS232 / Apple / Mac faq's without success.

What is the pin protocol for the IIc printer port?

All help warmly welcomed!

Antony.
