Linus! Please clarify in the first few sentences if this is the game of life or the machine creator!

The bash script is the virtual machine. The program that implements Game of Life is the directory tree further down the page.

Congrats on bringing one of the coolest self-modified instruments back to life! Double congrats on your code being readable after all this time, was it a matter of the code itself being easy to read, or did you leave behind good comments and other documentation?

You can use Ultibo for RPi instead of Linux. It gives kernel/kernel7 files which starts the RPi in seconds without any OS. No system means all the hardware is yours and assembly programming is also possible.
Because Ultibo has no audio driver yet, I wrote my own which uses 8 bit PWM @ 960 kHz sample rate with the noise shaper This gives a clear sound out of the RPi audio jack. There is also something like SID emulator (not 100% exact emulation and still buggy but most of PSID files can be played using it) )and 6502 emulator available.
Ultibo: https://ultibo.org/
Audio driver (beta) https://github.com/pik33/SimpleAudio
"SID-like thing" (written mostly in asm) an be found here https://github.com/pik33/ultibo_retro_gui in unit retromalina.pas
