It may not look like it, but the fact that these lights are on means that my breadboard computer will work, in theory

When you put it on a breadboard, connect it up and power it up, there is no 'working in theory' anymore. It either works or it doesn't. So I'm guessing your setup works. Congratulations. 🙂

@rendezvous it's such a fun thing to learn, and honestly not as hard as it may seem at first
There's a great website called z80.info, which has loads of resources for making a z80 computer
Also the z80 datasheet itself is probably the most useful document

@irene Incorrect means it does not work by definition.

@irene Okay. To me, there are only two things: it either works or it doesn't. I will agree to disagree. 🙂🙂

I've been re-watching the Ben Eater's 8 bit breadboard computer series lately. I've wanted to try to build one myself since then :D

@irene Okay 🙂

@Noobish Ive been planning on buying it

@-red how can you know that it works as expected in all corner cases and does so also one second in the future?

@electrineer Don't you think about the corner cases during design ?

@rendezvous
That cpu isnt fully functional yet.
The fully functional one needs more ic's

Everything is easy to build. You just have to spend the time to study it.
