Q: How can I connect the 100/ 200LX to an Apple Macintosh?

A: HP sells a serial cable to connect the 100/ 200LX directly to a Mac (part #F1016A, price: $24.95). This handles the physical link.

DataViz (1-800-733-0030) is a company which makes a product called MacLink Plus/HP Palmtop, which handles file transfers, and converts the HP 100/200LX application's files (Memo, DataBase, PhoneBook, etc.) to popular Mac formats (Excel, MacWrite, Word, etc.). One current shortcoming is that the Notes section of the 100/200LX Database/PhoneBook programs is not supported in the Filemaker translation. But this is reportedly being worked on.

MacLink Plus works with all the HP Palmtops (95/100/200LX). It includes the serial cable.

The best answers to generic PC/Mac connectivity are probably found outside this newsgroup (anyone know where?), but here's a shot at some alternatives:

Most any terminal program on the 100/200LX (including the built-in DataComm) will handle simple file transfers via Kermit = Xmodem, etc.

MacLink Plus/PC is a commercial package made by DataViz for communication between a PC and MAC. It is intended for use on any IBM-Compatible and is reported to work on the 100/200LX, and allow easy file transfer. But see above for a customized HP version that supports the HP applications.
