Default What is the absolute smallest instruction set do you need to make a working computer?

What's your guess? 100 instructions? 50 instructions? 10? Would you
believe just 1 instruction!? And that instruction is implied, you don't
even need an opcode for that! And you're not going to believe what that
one instruction is either! This video explains how it's possible.

Concept proposed back in 1956.

It is a computational model used for teaching. It would be too slow for
physical implementation. That it can be done doesn't mean anyone cares.
