MacTron

The place for Macintosh users who build electronics to discuss ways to use their Macs to design, program, and interface to those projects.

Kevin Coble has written an excellent PIC programmer package called MacPic and has an upcoming schematic capture program in the works.
Jim Lee maintains a Mac Electronics Page with some interesting links to Mac Electronics.
Klaus Kloos has a shareware PCB Layout package for the Mac.
Joseph C. Chavez also has a PCB Layout package for the Mac in Beta.
Protel has a freeware package called EasyTrax that I have not tried yet.
Capilano Computing has a free 30 day trial of the PowerMac version of its Schematic Capture program DesignWorks Lite.

I also keep copies of the messages sent to the list in the MacTron List Archives.
