Since I haven't had any LCD Kits available for a while, I thought I would clear up some details about the kit for people who want to try it on their own.
The LCD is a HD44780 compatible character LCD. It is connected to the Mac USB port using a Belkin F5U002 USB Parallel adapter. Make sure to get the correct version that uses a separate USB cable.
The pinout I used for the kit and the Mac OS X USB LCD Command Line Tool is available here: Beyond Logic Interfacing Example. With some minor changes to get power from the parallel port, the final pinout is:
Centronics Parallel LCD 30 1 13,14 2 30 3 36 4 29 5 1 6 2 7 3 8 4 9 5 10 6 11 7 12 8 13 9 14
Following this pinout should allow you to use the Mac OS X USB LCD Command Line Tool on your own cable and LCD.
