Built this last year based on Ben Eater’s 8-bit computer design using 74LS series ICs on breadboards.

Implemented core modules including registers, ALU, program counter, memory address register, and control logic. The LEDs are used to visualize bus states and output during execution.

Biggest challenges were signal stability and debugging wiring issues across multiple modules. Getting consistent clock behavior also took some iteration.

Overall, it was a great hands-on way to understand how a simple CPU operates at the hardware level.
