Speech Synthesizer

This is a circuit which could be built to allow the speech synthesizer to be placed in the PEB. I have not built one yet, but I do plan to down the road.

This design is by Joe Speigel

Please make sure that all wiring and soldering is double checked before re-applying power. Though computer components are pretty hardy some do not take to being wired up backwords or incorrectly. I have done my best to make sure that all diagrams and instructions given here are correct, but I can not be responsible for any damage an incorrect upgrade might cause. Also keep in mind that this will probably void any warranty :>).
