Real Size CPU Debugging

Did you ever imagine you could do debugging assembler really *by* hand? Using this 3x2 meter CPU demonstration model, you actually can ;-)

 

However it's supposed to be used for teaching purposes. It simulates an 8-bit CPU, you stick plugs labeled with asm commands in the RAM, switch bits with big switches and see the calculation steps and register contents on large lamp displays (of course not yet LEDs ;-) ).

 

Just funny what you stumple upon in our basement ;-)
