Added a Quick Start that shows how addition and subtraction is done. 

Attach the 8-bit Workbench™ at the top edge of the Byte Adder Subtractor to display the output of the adder. For input, use the Binary Keyboard or Hex keyboard that can attach at the bottom edge.

Instead, use bread boards to create your own LED output display and input mechanism, e.g. using DIP switches with pull-down resistors. See the schematics of our other products for inspiration how to wire this up using your own parts.

Kits are available now!
