My first computer:
TRS-80 Color Computer with 16K RAM & cassette
Mine was a TRS-80 Model I, 4K RAM and cassette. It was modded and tweaked and spindled and mutilated until it had the BASIC II interpreter, an expansion interface, a huge 48K of RAM, and two blazingly fast 180K floppy disks.
It was really cool in its day. I even built some interface circuitry that plugged into the expansion port so it could control stuff in the outside world. Man, that was fun!
I still have it around here someplace. I wonder if it works.
eta: Every time one of these threads takes a turn into describing the first computers some of us owned, it amazes me just how many
old mature geeks we have around APS. Then comes the realization that "geek" is often synonymous with "gunny".
