Back in the 90s, I had a Celeron 333 in a custom wood box under the seat of my Buick. It booted Windows 95, had a parallel port LCD attached and double taped to the dash. I changed the registry so it brought up Winamp instead of Explorer, and used an LCD output and keypad plugin. I had a printout of my music in a book and could literally go to each song by number. ... I wish I had photos of the whole setup, but I didn't think to take any at the time.
