I have worked with both vt100s and macs, and the numeric keypad behaves
differently from the corresponding keys on the main keyboard.
(If you have macterm, the mac's numeric keypad behaved just like the vt's,
and you can simulate the vt's arrow keys by shifting [or not shifting,
I forget which] certain keypad keys.)
One notable feature of the numeric keypad is that the shift key has no
effect on keypad numbers. Also, the vt (and mac in macterm) can be
popped into "alternate keypad mode" (with the code "=", I believe),
which causes the keypad keys to send specialized escape codes instead of
their usual characters. Dec's software uses those a lot, although I
don't know that emacs does. Finally, on GIGI terminals, all of the
numeric keypad keys plus the arrow keys are user programmable, as well
as being able to operate in "Norm"al or "Appl"ied modes (setup KP), as on
the vt100.
I recommend going ahead and buying the apple keypad. Macterm already uses
the extra keys as a vt does, and the mac obviously CAN tell the difference.
New mac software may use these keys (with layovers, possibly) for special
functions.
I hope this info is useful to someone out there...
