[Aren't you hungry...?]

	DO NOT solder in a keypad in parallel with your normal Mac keypad.
Aside from being foolish if you aren't proficient with the appropriate
tools, it won't work.  The VT100 does not send the same sequences from the
keypad as it does from the keyboard.  In keypad mode, the keypad keys send
escape sequences, whereas the normal keys send the normal things.

	This is a true remapping done by the terminal, and requires that the
keypad and the keyboard *not* be wired together. Also, Mac applications
using the keypad expect to get a different sequence of codes so that they
can tell whether or not the entry came from the keyboard. Look at Inside
Mac at the bitmap which tells you whether the option key was down, whether
the command key was down, whether the shift key was down, whether the caps
lock key was down, and WHETHER OR NOT THE INPUT CAME FROM THE KEYPAD.

	I do not mean to flame at the original poster, but it is crucial that
his honest mistake be corrected before people demolish their macs.
