[Josh Harper]

 hi guys
I have a coco 1 26-3001
does anyone know what the  pin sticking  at location on  tp12 on the board is for
this location had a wire soldered to it leading to a factory installed keyboard adapter  that allows u to use coco 2  type keyboards 
u can see the adapter pics in my  dropbox link below
