Step 3 - Building the B Register

A project log for SAP 1 Computer on Printed Circuit Boards

Inspired by the video series by Ben Eater, I am developing a set of printed circuit boards for the simple as possible computer.

This step involves building the B register. There is not much going on here, just a couple of latches (74ls173) and LEDs. The build was pretty straight forward with no glitches.

Next step will be to build out the ALU. This will be interesting!

And, here's the video:
