On the fault line between two moons.
(Note how night vision on "current moon" is blue but on the sliding moon it's green?)

You will need a floppy emulator of some kind at the moment, such as a CFX or MFX as it’s a .RUN file.
I’ll look into whether it can be converted to an audio file format.

I’ve been back trying to work out why the ZX81 AY-3-8910 based sound card won’t work.
All checks with a logic analyser show all the signals to be correct and all data lines hold their correct values for over double the required 100ns after the control signals change.
I’ stumped.

Sinclair QL without a keyboard?
No problem, use a USB one instead. 😊
I’ve just created a @raspberrypi.com pico board which can act as if it’s a keyboard matrix.
With correct software should be able to be used on any machine with 8 scan and up to 12 sense lines.
