As a small kid there were two devices I loved playing with.
The first was an IBM Selectric II typewriter that I would endlessly hammer on. As a toddler it was absolute gibberish, but the whirring and satisfying thwack noises it would make were irresistible. Though it was a short lived passion as my parents grew weary of the noise and the cost of ribbons.
I remember being about 2 or 3 when my dad brought home an IBM Personal System/2 which of course came with the Model M keyboard and my second noise maker. Clacking out basic commands in DOS to boot up my little indian counting game and blackjack from floppy. Every keystroke with a single pointer finger and a delightful twang.
After that was a long stream of rubber domes until one day in highschool I found that old Model M in the closet and was pleased to find it still worked. My friends at the LAN parties were much less happy.
