Old spectrum with power going in from power supply.Most of the rubber keys click when pressed which I assume means it's booting.Been in loft for 30 years and was working then.Unable to test on tv so have to sell as seen.There is a ding shown in photos on front but that was there few weeks after purchase and never affected performance.Opened up to check inside and looks perfect .No dust .Added the manuals even though their not in great condition but still usable.
