Some time in the mid-1980s, at the proud age of someteen and three-quarters, I wrote a booth-style Ceefax emulator for my BBC Model B and demonstrated it at the local college’s computer club. The president of that club was a professor of electrical/electronic engineering named Harry White, who unbeknownst to me was also the director of exhibitions for Techniquest, a recently founded hands-on science education center in the nearby city of Cardiff. Harry had next to no budget and a pressing need to have exhibit-control software written, and offered me a part-time job whilst school was out. That was how I discovered people would give me money just for doing my hobby. Four decades later this is still the case. Thank you Ceefax, and thank you Harry.
