Just a quick blurb... I recently introduced a humble Freeware PIC development system for the Macintosh. Check out my Web page: http://members.aol.com/fdeck/main.html The software integrates a source code editor, assembler, and "front panel" for an inexpensive PIC programmer device. Full plans and firmware are included for the programmer, which connects to the Mac serial port. I also sell a "partial kit" that includes a printed circuit board, pre-programmed PIC chip, and software disk, though I am happy to say that most users have had no trouble building the programmer from scratch without the kit. Right now, the system supports PIC16C6x/7x/8x, but not yet "data memory" programming on the 8x chips. I will provide gradual upgrades, but my ambitions do not extend as far as turning this into a professional-quality development system, since good products already exist in the PC-compatible world. I plan to expand this Web site with information on Mac-based data acquisition hardware projects, mostly based on PIC chips, and any other interesting projects I come up with. -------------- Francis J.
