Oh wow - I'd *love* to have a Computalker! I wanted one SOOOO bad
when I was 15, had just built my IMSAI, and had just seen "Wargames",
but they were SOOOO expensive! I even got the demo cassette with
recorded speech from one. I still have it. I've had lots of
computers with speech synthesizers on them since then, but I've still
always wanted a CT1. Would you be interested in selling it, or
trading it for something? There's a blurb about it in the Tandy
catalog on my web page, in the "accessory boards" section. "Highly
Intelligible, Quite Natural Sounding Speech, Uses Standard S-100 Bus,
Phono Jack Audio Output. Sounds are defined in real time under
software control. The synthesizer is controlled by 9 acoustic
parameters which represent the phonetic structure of human speech.
They are transmitted to the CT-1 at a rate of 500 to 900 bytes per
second, depending on the data compression techniques used."
