Speak & Spell and Speak & Math were some of my favorites toys growing up.
I guess the whole idea of a talking computer that you could control was what "spoke" to me ("spoke to me", get it? :)
Somebody (another geek from the 80's?) took the time to create a pretty cool online version of the Speak & Spell.
It seems to work very similar to how I remember the original Speak & Spell used to work.
BTW: I should have my old Speak & Spell and Speak & Math lying around somewhere. I wonder if they still work...
