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.

The Zen of Forth
Forth also requires very minimal resources to implement which can be fun in constrained environments. Here it is on a TI-84+ calculator[0] or even a computer in The Powder Toy.[1]
The runtime design is a little quirky but straightforward and you can extend the system as you execute (or even change interpreter semantics), or add optimizations such as some form of JIT quite easily.

Jonesforth – A sometimes minimal FORTH compiler and tutorial (2007)
Some time ago I wrote an implementation of Forth that runs on the TI-84+ and TI-83+ calculators directly inspired by Jonesforth.[0] It runs under TI-OS as well, but the amount of available space is somewhat limited. On another implementation I wrote[1] you have full access to the calculator hardware and memory from Forth.

TI-84 Plus CE Python Graphing Calculator
On the TI-84+, assembly programs still work and it's still a test-approved device. I wrote a Forth interpreter[0] that can interop with the syscalls as well

Retro not Vintage Week entry, my Z80 RC2014 Pro with floppy drive, YM2149, CF, Wifi, etc.
The backplane is the RC2014(TM) Pro backplane, a 12 slot backplane. ROM/BIOS: RomWBW https://github.com/wwarthen/RomWBW - I usually run ZP/M, but as noted on Github I can also boot other OSes: CP/M 2.2, ZSDOS, CP/M 3, NZ-COM, and more
- ROMWBW - UART I/O?
- CP/Mish is an open source sort-of-CP/M distribution for Z80
-
Did CP/M also run on Zilog Z180 or Z280?
Also, a very nice kit for a Z180-based system using RomWBW
What are some alternatives?
SymPy - A computer algebra system written in pure Python
cpmish - An open source sort-of CP/M 2.2 distribution.
Ndless - The TI-Nspire calculator extension for native applications
propeller-vt100-terminal - ANSI / VT-100 Terminal emulator for Parallax Propeller microcontroller with VGA and USB support
jonesforth_riscv - Jonesforth RISC-V port.
