My high school was the second in Melbourne, Australia, to get its own computer. It was 1971 or 72, and the machine was a Digital PDP-8/L. Eight kilobytes of real live ferrite core memory, one ASR-33 teletype terminal, and no external storage except for a paper tape reader and punch. You had to toggle in the first dozen instructions (RIM) through the front panel, which told it how to read the binary loader tape (BIN) which told it how to load the Formula Calculator (FOCAL) language tape. Somewhere around here I still have an ASR-33 Teletype fan-fold tape that produces a 1974 calendar with a nude girly picture done in multi-overstrike ASCII graphics.
Many were the hours lost on playing Lunar Lander, Towers of Hanoi and Hammurabi after school. I guess that's where my computer addiction started.
At college, we had a Control Data Cyber 76 (I think), and all our computing assignments had to be submitted on 80-column punch cards, or on optical-recognition cards if you didn't want to stand in line for one of the three card punch machines. Your results came back around half a day later on 15x11 fan-fold paper.
I left college and got a job as a computer operator on an IBM 370/158 mainframe. Can't remember the stats of the machine itself, but I will forever remember the IBM 3330 removable disk drives. Those disk packs weighed around 20 pounds each, and held a whopping 200 KILObytes of data. We had around 200 packs and 16 drives, and on an average shift you could expect to handle over 100 disk mounts. My right arm will forever be stronger than my left!
We had a hazing ritual for newbie operators - we'd tell them it was time for the monthly chad audit, sit them down with the chad bin from the card punch, and tell them to sort the chads into piles according to the punched out numbers thereon. Kept 'em quiet for a whole shift. 
The first PC (they were called "microcomputers" then) that I laid hands on was one that a friend had built from a kit, running CP/M. Don't recall much detail of that one.
The first PC I really got to use in any serious way was one of the first IBM PC XT's to hit the office, and the first machine I bought for myself was an Ollivetti M24, which was a souped-up PC-AT clone with a 16MHz 8086, 640KB RAM, a 20MB hard disk and Olivetti's version of DOS 3.2.
Thanks for the memories!
