B.G. Micro still has the SP0256 chip available, in limited
quantities. They also have a PC-style board that has the
whole thing (text-to-speech and synthesizer) for $49.95
complete. It runs stand-alone off a serial port. I've got
some of the chips and the board for development purposes,
and I'm planning to use it for a wind-talker. This gizmo
measures current wind speed and direction, and reports it
back via ham radio when the radio detects a particular
keying sequence sent to it.
