My first (and only firsthand experience) with Eliza was running it on a Mac 512 on probably System 6 in a 7th grade classroom (one of the teachers collected the old antique Macs the school was going to throw out and ran them in the back of her classroom). It got stuck in loops and frequently asked the same questions over and over, even at that age it was pretty obvious what it was doing, but pretty neat. Hopefully this genealogy gets updated to include some of the earlier versions
