I've also seen one exactly once. Back in 1998 my parents and I were down in Brisbane for a few days. One day Dad and I went into the city to check out some computer shops. We went to an AASP called "Macs Place", where they had a sort of a mini Apple museum in a corner. Anyway, it was a quiet day, and the sales guy there was telling me all about the machines they had there (a 512k, a IIsi, and a Portable), and let me have a play with them. The Portable I used was a backlit Portable running System 7.0.1, and from memory was quite a nice machine, if a bit big. That day was also the day when I first used a G3, a Beige G3/233 which was also the very first time I got to use a Mac on the Internet. Ahh, memories.
