"SPEAK AND MATHS Learning Aid, Texas Instruments 1980 - Circuit Bent noise/glitch synthesizer

This Speak and Maths toy has been seriously circuit-bent: by playing with the switches and knobs which have been added, you can get some particularly horrible noises/creepy sounds out if it, especially when pitch bending the speech synthesizer with the knobs on the right-hand side.

It's pretty mental, but great fun - and, it's an interesting and unusual alternative circuit-bent noise-source, than the much more commonly found Speak and Spell machines!"
