Radio Shack was selling this chip for several years.  I'm not sure if it is
still in their current catalog but even if it is not you can probably still
find it in many stores.

This chip (**) took the phoneme output id code and produced the speach sound
requiring only a simple amplifier.  Basically, you program has to go through
text and break it down into the correct phonemes which are sent to this chip.
Alternatively,  another chip (**), I think it was a CTS256, would take english
text and break it down in the phonemes for you.  The two chips complimented
each other and require very litter logic to produce a text to sound machine.
Both chips are/were available at Radio Shack.

Radio Shack also sells a design book for all their chips and includes a
practical project for using these two chips.  I remember that there was a
serious error in either this manual or the documents that come with the cips.
If you decide to use the schematic from Radio Shack, send me an E-Mail and I
will look up what the error was (address decode logic or something like that).


 ** Note: I may have the functions of these two chips reversed.
