4KB TRS-80 Color Computer, which would have been $400 in 1980. Wasn't my own computer as it was my father's and I was a bit too young to get deep into programming until 1983 or so.
First computer that was strictly mine was a CoCo 3 in 1986, and the first one I built entirely myself was a 486-66 back in 1993.
I was basically the same, although I think we upgraded it somehow to 16K. I remember typing in source code from magazines (Rainbow, in particular).
I thought MS Extended Basic on the CoCo was pretty cool.
Ended up moving to Apple ][ a few years after that, but still have very fond memories of the CoCo, even though everyone else I knew had something else and liked to refer to my computer as a Trash 80.

Yep, we definitely remember those first machines.
