BG Micro sold a board called I believe the CompuTalker, with the
SP0256A-AL2 and CTS256AL2/P pair, like the ICs Radio Shack sold. I have
one of these boards sitting in front of me that I recently mounted in a
nice case with power supply. Mine had some leaky electrolytic caps, but
fortunately the damage was minimal and easily fixed.
I found reference to it in this posting here:
I've temporarily (please save these if you want them) copied what I
could find in terms of documentation and schematics for these ICs here:
Photos of mine are included.
