I recently acquired a TI Silent 703 on ePay and just

worked right away. But I expected it to work at 300 bauds as
advertised, and to my surprise, it clocked at a the head turning
speed of 1200 bauds! Did they hot-rod it later in its product life?
It says MODEL 703 at the back, part no. 2310503-0010. I did not open
it up yet. Is this a hardware mod? Is there an internal switch that
can toggle it between 300 and 1200?

I'm drawing a blank on that PN. I'm scanning in the 1985 TI Express
Catalog right now and it only lists the 2310503-0001. I think there is
an int'l version -0003. Even if the serial port would work at 1200,
though, the printhead only does 45 cps. Pic of a supposed -0010 on
Worthpoint, but I don't subscribe for details or confirmation.
However, it would have to have something like the 2 char thermal
printhead in the 780 series to print without buffering at 1200 baud, I
would think. Dig some more in daylight.
