I have fond memories of the System 80 as my first computer. I bought business System 80 brand new for about $1200 in early '82 from Smith City Market. I figured that since I had a couple of tape recorders already that the additional lower case and numeric keypad would be more useful. The first game I wrote was a worm that increased in length and died when it hit itself. Next was firing at a randomly dancing * on the screen. Used it for essays at university too. Replaced it eventually with a C64.
