In the early 80s, my high got a few microcomputers (Ohio Scientific, if you're interested). They had a 6502 CPU, 48K of memory, and two 8" floppy drives, with a total of about 540K of storage. They came with the old BASIC Star Trek game - the one that used numbers for commands, rather than the one that used three-letter abbreviations. I loved the game, but when I heard we could actually make modifications, or even write our own games, I was hooked. I wasted so much time in the computer room over the next couple of years, they had to ban me from it, a few times.
I remember one of the math teachers proudly saying that, if we upgraded to double-sided floppy drives, we could get more than full megabyte of storage online.
