I still use a keyboard from a 1989 Packard Bell! its the only keyboard i have and about 3 of the keys have been ripped off and the keys stick all the time. not only that, but its so damn idrty that the keys feel grainy when you touch them.
But it still runs.
I got one at home for a printer server. I am giving my MMX 166, 64Mb, 2Gb HDD, 15 CRT over to my next store neigbour as payment for mowing the lawn.
BTW, the lawn big, and it's currently a jungle. It's easily 3 hours hard work, and was a computer that I would not even pay $50 for.
Yeah I Remember using old Typewritters, Although I havent seen one in ages. The oldest technology I've ever seen still in use is one of those reel to reel tapes, Also you know those old floppy drives that are really huge. A picture link is bellow:
