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.

PicoGUS: Emulate ISA Sound Cards (GUS, Adlib, MPU-401, Tandy, CMS) with a Pico
are the PIO blocks wide enough to handle an ISA bus? Or are you using a shift register or another port on the pico to interface with the bus?
edit:: looking at the schematic it looks like you have the address/data pins multiplexed on an 8-bit port: https://github.com/polpo/picogus/blob/main/hw/PicoGUS-schema...
Curious if you did the HW design first, or SW design first, or how you came up with this particular solution.

Cloning a Rare ISA Card to Use a Rare CD Drive
The projects I mention here are not clones themselves but ever cheaper PCB prototypes and microcontrollers make it a fantastic time to create hardware for old systems (ISA). Enjoy!
There is PicoGUS [0], a Gravis Ultrasound emulation, a Raspi Pico based PCMCIA WLAN card [1], EDO/FPM RAM modules [2], "Snark Barker", a soundblaster 1.0 clone [3]...
If you want more electronics stuff, I suggest you follow the creators of these on Twitter.

older similar project http://rayer.g6.cz/hardware/lpc_sio.htm
LPC is not without perils tho, there is trouble with DMA support as mentioned here https://flaterco.com/kb/ISA_chipsets.html
