Always nice to see a post about the Speccy. My first blog here was on that very subject. It's a probably big part of why I like games so much.
I was about 3 when I first played on it (a +2, like yours). It was never the best system on a technical level, but it still had some high-quality games. I remember playing the Dizzy games a lot. I think I owned all of them at some point. I only remember completing the first game, but I enjoyed them nonetheless. I remember Atic-Atac and Chase HQ, too.
I loved the Speccy mags. The Crash covers were awesome (and still are, for that matter). Used to have a lot of them, but they're no longer with me. If I could go back in time, I'd store them in a nuclear bunker or something (along with my Speccy and games).
I've been looking for that documentary after missing it when it aired. Thanks for providing a video of it. I'll give it a watch soon.
