0102: Instruction Register Emulation & PCB Design | 16-Bit Computer From Scratch

*Description* I tackle the Instruction Register for the Emulator and the KiCad design. It's a simplistic circuit, so I capture each bit of work in a single take and adjust the speed accordingly. But, do I really need an Instruction Register in the 16bcfs?
