On the Sun we have

  sizeof(char)  = 1
  sizeof(short) = 2
  sizeof(int)   = 4      /* on a MS-DOS machine this is 2. */
  sizeof(long)  = 4

I did try to globally replace all your unsigned int to unsigned short
but the problem previals.  It is unusual that the software crashes
at the macro ReadWordAtPC, but when I typed in the expression in you
macro into the debugger it gave me a value without crashing.  Weird.

Same here.

Couldn't after n clock cycles you just say the CAPs lock was released?

Goodluck!  I know X programming is a real dog.  I have 3 good manuals
with me but after trying it several months ago I haven't went back!
Hopefully when most of the other things have bowled over I'll get back
into the gist of things.
