It’s alive!

So it turns out my 1 bit ALU--which has both circuitry for our accumulator and a tristate circuit to write to our bus, works correctly! Over the next week my plan is to assemble 8 of them and hook them up to my ALU.

My accumulator boards just showed up!

They're nowhere near as complicated as the 1 bit ALU boards, but they do contain the accumulator circuit as discussed in our "Introduction to Digital Computers Part 4 video, along with a single tristate circuit for allowing the contents to be written to our bus, as discussed elsewhere in the same video. These accumulator circuits... Continue Reading →
