/diy/ - Do It Yourself

I'm planning on making what I call a "make shift computer". Essentially I want a mechanical computer that isn't like the kind I'm using right now to type this message on, but, instead, can be able to run a word pad of sort without being electromagnetic.

I don't actually care too much about the mechanical parts themselves, but, instead, I care about the "logic gates" and how they make certain processes work.

So I already know how to storage memory into binary through the use of the SR latch. I know how to add and subtract with an ALU as well. The problem is that I don't understand the functionality of other things in the computer and how they are set up through pure logic gates.

When I look up a guide on the internet, it doesn't actually explain it or it uses logic gate clusters instead of explaining what specific logic gates are needed to make it function this way. Please halp.
