I remember back when I had a TRS-80 and to turn it on you had to type in a bunch of commands.
I remember back when games came as hex code in magazines and you would type them in by hand (read: hours) and then play them and not turn the computer off because you had no way to save the game.
I remember loading games on tape (used audio tapes) and it would take like 30 minutes to load a game.
I remember getting a floppy drive (5.25") and thinking "wow. this is SO much better than tape".
I remember the very first time that I saw a hard disk (1981-1982 or thereabouts) and it was about the size a toaster ("full-height") and held a whole 10MB and it was unbelieveably fast compared to a floppy disk. As I recall it also got about as hot as a toaster and it cost something like $800.
I remember the very first computer that I built myself was a 386 and the day that I finished building it - the very afternoon - I had it in a full height tower case and I was on a 6 story building in Santa Clara, CA, when the 1989 Loma Prieta 7.1 magnitude earthquake hit and I watched the computer rocking back and forth on top of my desk and in the middle of this huge earthquake and I jumped across the room and grabbed the computer and then fell on the floor hugging it (yes, this story is completely true).
I remember my very first major overclock was an AMD 5x86-133 which I overclocked to 200MHz and it was stable. TAt the time, that seemed like about as fast a computer as I would ever need.
