My first computer was a Commodore 64, with the enormous 5.25" floppy drive (if you had a C64, you know what I'm talking about) and no hard drive. Gotta love those.
Here are the stats on my first PC...
(It was actually already somewhat below average when I got it in 1993. My friends had a 486DX2, and I was jealous.

)
386SX-16MHz
4MB RAM, which I later upgraded to 8MB
I don't remember the video card... I think it was a Cirrus
3.5" 1.44MB floppy drive
5.25" 1.2MB (high-density! w00t!) floppy drive
300MB hard disk
13" 4-color CGA monitor
No modem
MS-DOS 5 with a very sloooooow installation of Windows 3.1
I added a sound card later... it was a cheap one, I forget the brand
Of course, the first PC I used was back in 1985, on my grandfather's Honeywell PC/XT. That thing actually ran like a charm until about 2001 or 2002, when it finally gave up the ghost. I miss that computer...
