This is the CircuitVerse Catalogue of Computers, a list of every computer I am aware of on this platform. I apologise for search optimising the Femto-4 and consequently burying other computers. If you have made/found any other computers do comment and I can consider adding them. Also please comment any corrections. This should also make verifying originality a lot easier.  

Completeness is based on the description (if it says it is complete).

What am I counting as a computer?:

A computer will be classified as anything that executes some form of code. It will not include calculators or isolated ALUs, though isolated CPUs are included. Additionally, things which are technically a computer (such as Conway's Game of Life, and Turing Machines) will not be counted. In the end, the measure is if it feels like a computer, it is. 

What is complete enough to count as a complete computer?:

Provided it looks like it took some time to make, and has actual circuitry rather than an empty project, it will count, regardless of how dysfunctional it is. Since I do not have the time to verify if computers actually work (since no one explains what they actually do or have nice user interfaces), I will take the descriptions as the description of what it does. 

What counts as a different version of the same computer?:

Essentially provided the labelling, forks, or description implies that it is the same computer, but updated, then it will count as a variation of a computer and not a new computer. Generally, if I view a series as incremental improvements to the same computer (e.g. Femto-4v1 vs Femto-4v2) I will not include them separately (though may include a link to the series overview as well) I will attempt to include only the latest version of the computer.

My computer is not on this list. It is called the rixis emperor r1 it is a work in progress and I have no idea how many bit it is as it has a lot of splitters in it. It takes inspiration from sjp4's string cpu (we are friends)

It has been done

Please remove my computer(Rixis emperor R1) As it is broken and I am not planning to update it anymore.

My new computer the rixis combinox r1 is not on the list. If you can, please add it. It is 16bit.

I made a new computer called the STRING32000 it is a 32-bit CPU with a different architecture and instruction set from my old 16-bit series. Could you add it to the 32-bit list if possible? heres the link:
