[comp.sys.mac] External Numeric Keypads

Need a little info...

I posted a few days ago about finding a numeric keypad to go along with my
old keyboard now that I have upgraded to a Mac+.  I can't bear to part with
it.

I have since run across a product from Cambridge Automation called a Numeric
Turbo.  It combines a trackball (identical to Turbo Mouse) with a numeric
keypad.  "Great package!", says me.  Then, in fine print, the bane of all
upgradees:  "Incompatible with Mac Plus".  Woe is me.

Then I thought about it.  Is it really Mac+ incompatible, or will it just
not work in conjunction with the Mac+ keyboard?  I'm not too knowledgeable
in this area, but it seems that since it worked with Mac 512, and the
key codes couldn't have changed much (or else the old keyboards wouldn't 
work), that it would still push out char codes that could be interpreted, but
may conflict with those pushed out by the new Mac+ keyboard.

Am I all wet?  Does anyone have access to knowledge of this beastie or,
even better, be able to test this combination out?

Any help is appreciated.

I would look for a dealer to let me test it out.  It might be a problem with
the Mac Plus keyboard, or with the 128K ROMs.  Even the Apple numeric
keypad has some trouble on the 128K ROMs.  Also, be sure to test it out
on system 4.1, as some of the third-party keyboard software is incompatible
(they modify the driver code in-memory <gag!>)

My recommendation is NOT to buy this product unless you can test it thoroughly
first.
