A typewriter!  Back in my day we heralded the invention of paper.

OK, my first PC was a TRS-80 model I with 4K of memory.  I bought it the day it was released, and had a text-based football game programmed 2 days later.  Later on, I went the Commodore route with a Commodore 64, then an Amiga 1000, 2000, 4000, etc.  Bought my first 3D software for that machine.  Been hooked ever since.

And I'm still working on my first novel.
