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.

Simplest Kansas City Standard modem for a 6502 computer!
My code is a bit hard to read because of some APRS NRZ decoding mixed in with the KCS decoding but essentially I’m only measuring if the correct amount of cycles have passed(throwing away the other cycle data) and then detecting if the wave had a length above or below a threshold of $0600(somewhere around 1700Hz) timer1 counts (at 2MHz in my case). That leaves plenty of headroom but has pretty bad immunity to false zero crossings. You can have a look ca1irq: https://github.com/AndersBNielsen/abn6502/blob/main/abn6502rom.s
- I need help figuring out how to create a multiprocessor setup with 2 6502 CPUs.
- I want to make my graphics card on a pcb. Which software should I use to design the pcb?

6502 Coding in C or C++?
I’m using it for mine - same memory map as Ben’s. I only use the assembler for now though but will use the compiler some time in the future. It’ll probably help you get an idea how to set it up: https://github.com/AndersBNielsen/abn6502

The Apple Event logo looks pretty good in mono High Res (HGR) as well!
In my 40+ years of doing graphics programming I've never heard the term color attribute used to describe the high bit / pixel shift. But then again I don't do a lot of reading W.R.T Apple 2 graphics due to personal experience of just using it. =P

Pixel editor software?
Another bare-bones alternative is my HGR Byte Editor. Includes both HGR and DGHR pixels editors and assembly source.
What are some alternatives?
