A CC: Tweaked addon
Originally this mod was intended to add more autonomy to turtles by allowing turtles to "reprogram" other turtles, then I realised you can already do this.
Turtles can place drives and edit disks, by default all computers will run "startup.lua" from the root of a disk in a drive
But I do also think this repo is a good simple example of how to make turtle peripherals for 1.20.1
it took quite a while to figure out a "Minimum Viable Product" for turtle peripherals.
