Hello Everyone!
I am searching for a Silicon Systems SSI-263 A/P phoneme speech synthesizer integrated circuit (IC) for restoration of an Applied Engineering Phasor sound card.  Compatible ICs are also identified as Votrax SC-02 and TDK/SSI-78A263 A/P.  Please contact me if you have one for sale in verified operational condition.  Thank you.
