So here it is, my first creation, way past prototype, the ZX Spectrum 48k usb-c powered.

(pending some further tests, but this will probably be yours @carlosefr )

@luisfcorreia The irony of a Spectrum powered by a 100W-capable cable.

@carlosefr I'll have to figure out a way to mount a tasteful reset button

sometimes it does not power up correctly and requires resetting

@luisfcorreia No way to hold it in reset for a short while after boot? Something simple like a capacitor + resistor?

@carlosefr yes, there's a capacitor, 1uF, I've increased it to 2.2uF and it works best but not fool proof

@carlosefr just tested, 10uF works and fixes it

it takes 5 seconds to boot, but that's OK
