August 2019 Update

We continue to get requests for this Demo Board so we have chosen sell a kit of parts. Construction is not difficult but does require some electronic skills.  The kit contains only the programmed microprocessor and the schematic so you have to supply a prototype board, a power supply, and a few components. Check our eBay store for details.

Two customer sent us photos of their boards so you can see the complexity of the build.  This one was built on a prototype board.

This one was built on an Arduino UNO board.

After selling 300 of our vintageTEK Demo Boards we have decided to retire the item. Demand has slowly decreased for the Demo Board and it just doesn't make sense for us to buy inventory at the economic order quantities.  We want to thank all our customers who bought this board and helped support the museum.  We hope you enjoy your purchase.
