Mine was, actually it was my brothers, Atari 130XE, but my first real one was an old IBM PS/2 Model 30 with a 10M/B hard drive. I'd love to hear what everyone started on, whether that's a Commodore 64, a Tandy, a Windows 95 tower, or a hand-me-down family PC. Bonus: what's the first thing you'd do with it if you got it running again today?
