My early programming was on BBC Micro and some Acorn machines in school. There, the programming and documentation was all spelt correctly, from memory. "colour", "dialogue", "catalogue", and so on. It wasn't until I started on a PC that I got the Americanisation of computer stuff. To this day, I still name things internally with the spellings I'm used to despite working in an international company (where it makes sense of course, not in a way that might lead to actual time wasted due to confusion.)
