The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

BEAM Computer!
I found invaluable ideas in Tom's NQSAP 8-bit computer (both breadboardand PCB builds) that features most of the 6502 instructions and addressing modes. NQSAP led me to deep dive into overflow, ALU understanding, learning about glitches and in general to assimilate a ton of clever ideas that Tom leveraged in his builds.

connect the worlds worst graphic card with the 8 bit cpu?
I’m currently finishing up a modular PCB version of the design that has a few optimizations to minimize the EEPROM issue. Once it is finished, I’m planning to see how fast it can be clocked. There is a lot of documentation on the breadboard version here and the PCB version is in the same repo: https://tomnisbet.github.io/nqsap/

16-Bit Processor (Step 1: Approach to Bus and Modules)
Sure thing! I have a write up on github, along with all of the schematics, microcode, and support files. The original breadboard version is here: https://tomnisbet.github.io/nqsap/

Also this guy did some decent documenting. https://tomnisbet.github.io/nqsap/

What to do with your build post-project
I started with an 8-bit SAP-1 design and then added on a bunch of extensions until it had many of the equivalent instructions and addressing modes of a 6502 processor. As the build progressed, I documented it all on this github page.

First set of boards for an 8-bit build
Just got the first set of boards for my PCB version of the 8-bit computer. The computer is a new build of my NQSAP design. The PCB layout is based on this post from u/djh82uk: https://www.reddit.com/r/beneater/comments/pn4j6j/finally_complete_with_all_bugs_fixed/ with a few changes:
What are some alternatives?
