Sir
Oh my, that screenshot of the startrek game sent a shiver down my spine - I haven't seen that since we played it on the Commodore PET our primary school got back in 1980 (I much preferred the PET to the ZX80 that came along).
It's true that only the interested managed to get to grips with the thing - I used to sneak in at lunch-times to use it when no-one else was around (It was a blacked out room so you can imagine how exiting that was for a 10 year old boy :) )
By the time we were taking Computer classes at secondary school we were into the teachers strike phase and O'Level/16+/CSE fiasco. Our computer teacher left for industry, the next person to take the class over was the Maths teacher - he made a pretty decent job of it until he too buggered off into industry.
We were then left with the History teacher - who had trouble just reading stuff from the book. It fell to me and a friend to get the rest of our class through their O'levels, thus setting my working pattern for my career. We were very proud when most of the class actually passed their O level. However the whole situation put me off going into teaching and just stick to on-the-job stuff these days.
It's also true that attitude is worth more than intelligence.
