What happens if you bash keys on the //c keyboard (hyperterminal should show
those characters)
I suspect you problem here is the pin numbering! The apple version doesn't
match that on the keyboard connector (Been there done that) I can't remember
what the exact difference is I think one numbers clockwise the numbers
outwards from the middle pin i.e. (NOTE THIS DIAGRAM IS WRONG!!! THE CORRECT
ONE IS ELSEWHERE)
1   5  1   2
 2 4    3 4
  3      5

It DOES work I boot strapped my //c using the same method. Just remember to
add the delays to the hyper terminal end.
