The Commodore 64 got me started in computers, back when I was in grade school. Countless late nights programming in BASIC. All this time I never knew BASIC was licensed from Microsoft. Thanks!
"Commodore licensed BASIC from Microsoft in 1977 on a 'pay once, no royalties' basis after Jack Tramiel turned down Bill Gates' offer of a $3 per unit fee, stating, 'I'm already married,' and would pay no more than $25,000 for a perpetual license."
I still have my C64 (it only needed some capacitors replacing a few years back) from about 1984ish but for me it was just a games machine although I did type in an awful lot of machine code from books later on.
I still remember the ADSR (attack, decay, sustain, release) thing and low pass, high pass and band pass for sound and have some unlikely memories about graphics primitives too for a middle aged bloke!
My original Quickshot II still works. You might bear in mind Daley Thompson's Decathlon was popular in the UK back in the day and it was designed to destroy joysticks.
