Overclocked TI Silent 703 at 1200 bauds?

[Charles]

Please excuse the hijack:

I have two Silent 700's, I think the 745 models with acoustic coupler 
and 110/300 baud rocker switch. One I have fixed and it works great 
(well, at least as far as that silvery thermal printout goes).

Unfortunately one has three bad keys and at least one missing column on 
the printhead (yes, the head itself is bad). Does anyone have a junker 
from which I can buy three keyswitches and a printhead? :)

thanks

Charles
