Need help connecting a 41CX to a PC Message #1 Posted by Steve on 4 Jan 2003, 8:58 a.m. What are my options for connecting a 41CX to a PC? I'm assuming I need an HP-IL module, plus an HP-IL RS-232 adapter? What is the GPIO interface? Finally, what software is available to transfer to/from the 41CX assuming I have the right hardware? Thanks! Steve

In any case you'll need an HP-IL module for the HP-41. In the museum forum archives are some discussions about those options. Christoph Klug could be the man. He's working much on the IL stuff, and has developed a new IL card for the PC. Regards, Raymond

You should contact Christopher Klug. With one of his cards, you'll only need the hpil module.
