The Digirule2 is essentially an 8-bit binary computer of the 1970's, built into a 20cm ruler. It features an 8-bit address bus, 8-bit data bus, data input buttons and 33 instructions for you to code your own programs.

With an instruction set consisting of 33 instructions - the Digirule2 can be programmed to perform all sorts of tasks, including fun games such as the classic 'kill-the-bit' game for the Altair 8800 or perhaps a Knightrider LED scanner, binary counter or a simple game of two player pong!

An excel spreadsheet allows you to easily write your code in mnemonic form - it will then automatically convert it into binary machine code for you to enter into the Digirule2:
