Conditional jump instructions (2018x3)

Air date: Apr 21, 2018

In this video we program the microcode of the 8-bit breadboard computer so that it supports two conditional jump instructions: JC (jump carry) and JZ (jump zero). We also test out these new instructions and write several programs using them.
