programming docs for old external speech synths

Huh, I never considered looking for a datasheet!

Hey, their v-stamp product looks pretty cool.  It looks like it's designed
for hobbyist and prototyping applications.  Almost as useful as an AVR on
a DIP carrier.  Especially useful because, well, I don't do SMT soldering
very effectively.  I'm blind, you know.  *grin*  There's probably a method
for doing it, but I've never learned it.

Hmm, this defines the protocol, but I wonder how much of this protocol is
required by the average synthesizer.  Some of these commands are, I'm
positive, not used on most hardware synthesizers.  The last DoubleTalk I
saw definitely didn't have voice recorder features.  *smile*

I've actually considered just trying to buy an old serial-fed Accent, but
this is a much better solution.  (With the right tweaking, the accent can
sound IMO almost as good as the Keynote Gold, which is my preference.)
