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.

“33% of GStreamer commits are now in Rust”, from the 1.22 release notes
There's an LLVM fork with Z80 and eZ80 support if you want to start work on that yourself.

Motorola 6800
Very cool. While obviously not ideal, the results are probably accurate within a small factor. Unfortunately there's no assembly version for 65C02 but Z80 does surprisingly well in this test.
I muse what could be done with modern cross-compiler (SAT solving for optional code sequences?) A llvm backend for Z80 has recently kicked back into gear: https://github.com/jacobly0/llvm-project
- What can C do that C++ can't?

First ever Rust code compiled for 8-bit 6502!
I also found this Z80 port of LLVM here: https://github.com/jacobly0/llvm-project It seems to be somewhat active and there's also an issue about Rust: https://github.com/jacobly0/llvm-project/issues/15

Connecting a 1980s Pinball Machine to the Internet
https://github.com/BallySternOS/BallySternOS
ballysternos is a really neat arduino project that sits on the debug header of old bally and stern mpu boards. the arduino holds the 6800 in halt from the start and re-implements game code
i've seen at least two of these in the wild, one in a Bally Eight Ball running "Eight Ball Plus" code, and another in a Stern Meteor running "Meteor 2021". both add some neat super-features and game modes, the Meteor has an accompanying wav trigger board, speakers, and amp to add wav sound effects as well -- anyone who loves Meteor will appreciate (or hate) that it no longer screams your spinner value in a high pitched tones.

Electrical question for SDU board - Sharpshooter
Here's a similar project for old bally/stern games that might help programming wise. https://github.com/BallySternOS/BallySternOS

Motorola 6800
a lot of pinball machines are based on the 6800. i've been really impressed by one project that replaces the 6800 with an avr by just wiring up all the relevant pins and holding the 6800 in halt:

i've started working on a derivative project using an rp2040 instead of the avr with hopes of offloading the 6800 bus work to a pio

GALAXY 2021 - a rewrite of Stern Galaxy (1980)
For a board, you can wire your own prototype, get a kit, or order your own PCB from Gerber files. Here are schematics and files (USE V3 FILES): https://github.com/BallySternOS/BallySternOS/tree/master/Schematics
