A fairly unexciting video, spoiler alert, nothing blows up :)

Testing that the board will survive an original ZX Spectrum reverse polarity power supply being used. This scenario would damage a Kickstarter 1 (Issue 2a/2b) Spectrum Next and render it inoperable.

The Issue 2E board (Spartan 6) is the same as the newer Issue 2H (Artix 7) in terms of the voltage protection element.

Remember, original Spectrums have a centre negative PSU connector and the Spectrum Next has a centre positive PSU connector. Don't get them mixed up :)
