The Votrax Personal Speech System

An SC-01 Based Speech Synthesizer

This is more of a holding page now for my Votrax Personal Speech System (aka PSS).

I will be adding more info here as time goes on and I figure out more about the hardware workings. There is absolutely no technical hardware information about this device on the internet until now.

Currently, I have unpotted the black "brick" inside the unit, and I have reverse engineered the circuit in there and dumped the ROMs, as well as made a clone of the brick.

HERE is the procedure I used to unpot the module.

HERE is the making of the clone module.
