As far as I know, there was never a Unibus version of
DECtalk. The
DTC01 was connected via a normal serial port, and could be used on
any machine. So DEC didn't really have a need to have a bus based
card developed (they did later, though.)
Of course I meant to say QBUS:
"M7132 DTC04 Q DECVoice main processor board (dual height)"
(Btw, Stephen Hawkings used a DECtalk for many many
years... :-) )
Which sparked my interest of course, his voice has become a celebrity in
itself.
Thanks,
