Lol! My first was a Headstart Explorer. 8088, 512K RAM, CGA monitor, and the "optional" 20 MB HD:

The obsolete Computer Museum

What's the dot pitch on that? .39? .41?

First used (IIRC, a PDP-11, I was a little kid then and my mom worked in a datacenter, the programmers were friendly and let me mess with it)

First owned (Atari 400)

First PC used (IIRC Zenith 8086):

After that, bought a 486/66. Doom rocked on that machine.
