DG One owners? I think I have something.

[Chuck Guzis]

A kindly donor sent me an external numeric keypad from Data General.  It
has the right keycaps and color for a DG One laptop.   Model number
2568.   Connection is via a 3-terminal plug; basically a miniature
stereo headphone plug.

I'll give this up to a One collector who can identify this for certain.
Otherwise, I'll probably repurpose it.   FWIW, it appears to be
unsued--not even the rubber feet have dirt or wear.
