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.
