I saw one of these today in the Rochester Play Museum (which, btw, is totally awesome) and it brought back a host of memories from my childhood. We had a Little Professor calculator when we were kids to help hone our math abilities. We also had the infamous Speak and Spell. Now I see that my love of gadgets has gone back a long, long way. The Little Professor was introduced in 1976.
