Can someone please show me the pinouts of the connector on the back of the Apple IIc. It is a 5 pin din plug (female) that I wish to plug my Hayes Modem into. I want to build the cable (I have the parts) but do not know the pinout details (and it is not in the manuals that I got with the unit UUGH!) I need this information ASAP Thanx Mitch -- +-----------------------------------------------------------------------------+ !

Pin-outs for the Apple ][c, and lots more, are available in the _Apple ][c Technical Manual_. I'm not at mine just now. Original two volume version was published by Apple. More recent one volume (thicker) version, cira 1985, is from Addison-Wesley. It's possible that there is a post-1985 one. ****DISCLAMER: My comments, etc., are my own shakey opinions ******** | Bruce P.

Here are the IIc port pinouts. //c Pin RS-232 Pin Sig. Name Description 1 20 DTR Data terminal ready (output) 2 2 TXD Transmit data (output) 3 7 GND Power and signal ground 4 3 RXD Recieve data (input) 5 6 DSR Data set ready (input) Since a number of RS-232 pins have no //c equivalents, this disables some of the features of the connection. However, it's easy to write software to get around this. Good luck. Dave Rutherford | In mortal combat with DGR0093@RITVAXA | four-line signatures!
