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.

Modern CPUs have a backstage cast
Yeah. To my knowledge nobody has used the SP-less boot mode. But the 'Go' signal is definitely sent over FSI and not just a GPIO. The BMC code that does this is here:

Bare Metal Emulation on the Raspberry Pi – Commodore 64
See also, PiTubeDirect[1], which runs on a Raspberry Pi which you have plugged into the second processor port of a BBC Micro[2], and turns the Pi into emulator for a number of different processors, notably an arbitrarily fast 6502, a Z80, or an 80286.

Modern CPUs have a backstage cast
IMHO this makes the PiTube Direct project perhaps even more impressive: it attaches emulated vintage microprocessors to the BBC Micro Tube interface, implementing the Tube circuitry in software.

Raspberry Pi-based mods for retro consoles/computers
BBC Micro/Master - PiTubeDirect - emulates a load of second CPUs for for BBC. Lets you run CP/M, DOS.

Pimp my Beeb
It's a shame he desoldered the tube connector. He could have used it for a pitubedirect (https://github.com/hoglet67/PiTubeDirect)

Connecting an 8086 or 8088 processor to a Raspberry Pi
There's a similar project for the Acorn BBC Micro called PiTubeDirect, which allows the Pi to emulate several different CPUs, while connected to the BBC Micro's "tube" second processor slot.

(The BBC Micro itself was quite remarkable for supporting multiple processors, which did not have to be the same architecture as the host 6502.)

Finally! I'm the proud owner of a BBC Micro again!
If you ever do want to play with Tube like this, I've heard of https://github.com/hoglet67/PiTubeDirect - not got around to trying it yet - but I want to.

Found this copy of Elite in my loft the other day.
I expect the tube version will be for 6502 3mhz, but worry not! https://github.com/hoglet67/PiTubeDirect/wiki
