To all interested, I need to work on documentation.
It's easy to use, it just should come with it.

Adding the USB interface would give the advantage when porting to Windows CE for the PocketPC world. Still on my wish list.

I just bought a ZipZap and like a Dodge Ram Clone, the Forward and reverse are backwards from Microsizers. BUT, as my software handles each car individually, not a problem. I allow the software to dynamicly map the pins per car.

Someone asked how does it work?
The question is, how much details do you want/need?

The software drives the computers parallel port connected to a NoxBox. The NoxBox is connected to a specific MHz Remote controller. Selecting a 'Forward' direction through the software interface, asserts a line to the NoxBox which drives the remote controller to press 'Forward'. Same for each direction available.
