Hehe, reminds me of High School back in 1975, when the school had only one computer class ( for Honors Seniors only!!) and that was via an LA-36 DecWriter and 110 BPS accoustic modem to the local Data Processing service, where a PDP-11 running RSTS/E BASIC would service hundreds of time-share customers, including our High School.
I was lucky enough to have had an HP-65 back in 1975. For Geometry 2 class, I passed the finals with an "A" after the teacher noticed I was using the calculator, he asked me to explain to him what I was doing, and I told him I wrote a program on it to factor polynomials. I showed him how it worked. He smiled and said "If you know it well enough to write an algorithm to do it, you KNOW it. You pass!"
