1971 (by correspondence!) in 3rd form, with a forward thinking maths teacher who had us punching simple  programs on Portran cards using a paper clip, which were the sent away to run on the Massey University computer, and results returned to us the following week.

1973 saw the school buying a Digital  computer which was kept in my 5th form maths classroom. This had the advanced ticker tape attachment which meant you could avoid retyping in your programme for lunar landing games each time! No such thing as a VDU at this time though - all paper output.

(About this time for $100 you could buy a pocket calculator with the 4 main functions on it - for an extra $15 you could have one with square route!) (And to put that price in perspective a gallon of petrol and a packet of 20 smokes were both 48c.)

After that  a progression through Sinclair Spectrum, C64 then the wondrous DOS based 286 with paper white screen, and a wondrous 20mb hard drive.(Which cost about $2,000) (Who can remember when DOS 5.0 release was a big thing?)

A late entrant to the internet, not until early 1990's.
