The BBC Micro was (almost) my first home computer (when I was about 8 years old). I can remember spending many a happy afternoon typing in computer programs from magazines only to find they didn't work right. I can also remember playing Elite (which I also played on the Commodore Amiga years later).
10 PRINT CHR$(141) "Dixons is rubbish"
20 PRINT CHR$(141) "Dixons is rubbish"
30 GOTO 10
For something more nostalgic, you can load up the original Elite and try to dock your ship back in the space station. It's a lot harder then I remember ;-)
