<slight rant> I remember these mysterious computers from primary school... I never got to even touch one, only the "cleverest" kids seemed to be blessed with the chance to use it and merely to learn typing - remember when that was considered a skill? Later on in the mid 90s my dad got me an old Atari ST where my first exposure to programming and fun with computers began, It might seem dated by that point but I am still extremely grateful for it to this day.
I will never know how useful the BBC would have been. My memory of schools back then were not the most inclusive, they seem to arbitrarily decide who should and shouldn't get a chance to do something based on their perception of who is the cleverest.
