Re: You are in a tunnel. There is an echo here ...
Careful there, because the Spectrum Vega actually appeared. It's basically an 8-button device to plug into your telly. The handheld Vega+ is the absent one.
Even got a listing on Amazon: https://www.amazon.co.uk/dp/B013BC7IR6/
Not that you can buy one now (or ever again, because it's Retro Computers).
