I'm only 59. I see at least other poster has used a TI 99/4A. I've been using an Amiga since 1987. I have an A1200 that I bought new in 1992 (one of the first delivered to this area) and it is still running fine, if somewhat modified now.
We still have one active Amiga user group close, in Washington D.C. (NCAUG) that meets every month!!
