The thinking in my perspective is , but why are all those there, why they are named differently , in videos i could learn about their existence , what the letter stand for, and how some were introduced over time, but it's a bit different perspective than how to use them in a precise situation ...

Important: The 0000 address (0th signal of 0th X combinator) is cursed and must never be used. It is marked with RED signals in the blueprint, do not assign any values to those.

Since you're (mostly) not using Each, I'm surprised a zero signal is giving you trouble.


The problem is that in ...

Don't worry about inserting the "dummy" opcode as you called it, that's just an optimization thing. The end result is still the same if you don't use that, it'll just take a few ticks longer because the CPU inserts an extra delay to allow the flags to properly update in that case.

Besides, I wouldn ...

The possibility to do each red-wire / each green-wire and the possibility to add much much signals/data onto a single constant combinator seemed to me so powerful that "it would be easy to find a spot where it could be used", but when studying a bit more the CPU, ehh it's not that clear anymore ...

What I had in mind is that the 2.x new features (selector combinator, mostly) wouldn't be of much benefit in the context of this particular design .

Would it be possible to design a different(better?) CPU that relies on the selector combinator? Quite likely - but I haven't done any analysis of that ...

Thanks for confirmation, I've updated the OP with the fixed blueprints.

And yeah, you are correct - the CPU does not use any Space Age or even 2.x new features. In fact, it was developed and tested by me in 1.x.

There is in fact a very good reason why I'm staying with 1.x for the time being - and ...

Unfortunatly i am unable to tell if it's preventing the machine to work, because i don't know what i should be seeing/not seeing. But there's an error message referering to the removal of the rocket unit control as item in space age when importing the blueprint that has a display connected to it ...

Thanks.
No scripting was involved, the only "tool" I used was MS Notepad for writing down all my notes.
Well, that, and of course Factorio's built-in map editor - to allow single-stepping through the simulation ticks while verifying the correct propagation of signals. Would've been a heck of a task ...

Here's something I've been working on for the past few months.
I wanted a good CPU to help automate tasks which are too complex for the more usual kind of Factorio combinator logic - but I couldn't find a nice design that I particularly liked, so I made my own CPU instead.
