Headwaters Management commisioned the layout, and pilot production, of this board for one of their customers. It communicates between a parking meter, and a palm top computer. Software for it, and the palm top computer was written by Sherr Pullen of BrassRat Communications. I think I did about 12 boards like this.

Later, I cleaned up the packaging a bit, and ended up producing 12 total units in this configuration.
