very good ;)

here's one using 2 combinators:

Without power, combinators don't change their output, no matter their input.
So when you disconnect the arithmetic combinator from the power network, it will still output A=1

For a one-time-counter, use 2 decider combinators: one with x != 0 -> x (input count), the other x < 60000 -> x (1), wire all in- and outputs together.
Activate the inserters from the output of the second combinator, when x = 0.

oh, I only searched for "PREformance", a posteriori that wasn't enough

To reproduce, press F4 in game, it says "Capture preformance statistics".

hey guys,

i am sorry for my late answer, i had not much time/spirit for factorio lately, still I've got a bit of progress.

I've tried to figure out some ways to reduce the amount of cells, I screwed the same way like you did :) I was imaging a design quite like yours, but I also forgot the fact ...

zaubara, I tried to look at your 4-Bit-CPU.zip file. It downloads as a 67,466 byte file, but when I try to unzip it:


C:\temp\factorio>unzip 4-Bit-CPU.zip
Archive: 4-Bit-CPU.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a ...

* If you have your constructs in a single game file (e.g., "4 Bit Address, 4 Bit Data RAM"), you might want to consider adding a save game in the first post. It's just really hard to make out what's going on in the pictures with lots of stuff in them. Plus, people can't tweak and play with the ...

So (just looking at the diagram, because reading your text and downloading .zips would be "cheating"):
I won't tell anybody :)

Top "SEL" is for selecting between 'move' and 'alu' operations.
Middle "SEL" is for selecting between move/alu and "IO/RAM" reads.
Bottom "SEL" is for selecting between ...

I have prototyped the CPU I am building in Logisim :
http://i.imgur.com/2aPeEGp.jpg
It is a 4-Bit CPU with 20 instructions (3 unused), every instruction is 12 bit wide and executed in two cycles, the program memory has a capacity of 64 instructions.
Implemented instructions: ADD, SUB, AND, OR, NOT ...

I've got it running in 0.11.10, changing line 13 in file prototypes\actuator-entity.lua from: to: Seems to work as before, but I am not sure

Thank you
I did not know that post, seems the forum search function has some flaws... good to see there are more people interested in this topic

Hello,

Now that I have my factory running and producing everything in high volume, I decided to experiment with the game mechanics to form binary logic gates and perform math operations.
This is what I came up with:

These are my basic cell arrangements to form the ...
