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: 
https://groups.google.com/u/1/g/comp.sys.tandy/c/X_6fSse6As4

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.
