Actually, I have a feeling this may have been a prototype for a commercial 
project -- how else to explain having interfaces for all the common interface 
hardware standards?  At least this one isn't touting a kit of parts, or a PC 
board for sale.

I'm just remembering the decision a few years ago to cut 'way down on contest 
coverage because they didn't have space!
