Vintage Grandstand My First Computer - Powers On I’ve tried to test it, but I don’t understand how it’s meant to work. The buttons are responsive most of the time, but sometimes they’re not. It may be different modes or it may be faulty. As I can’t tell if it’s working properly I’m selling it as faulty, spares of repair. Please see pictures for full details. Dispatched with Yodel 2 day courier.
