Hah! Fantastic stuff! And of course Your Sinclair is a prime nostalgia trigger all of its own. Do you remember Bamboozle (I think it was on C4 rather than Ceefax.)
Funny to think about how little media we had back then, when today I can pull a slab out of my pocket and access a significant fraction of the world's movies, songs and books instantly. Reckon I had more fun then though, but that might be because I didn't have a hellish job and a family to feed. Ah well.
Cheers for the memories. Better stop now or we'll end up talking about Bagpuss and the bloody Clangers like a pair of students.
My aunt and uncle used to look after me and my sister when we'd finished school before my mum finished work, highlight was group playing Bamboozle. It was awesome, then occasionally the signal would die and it'd ruin your game.
