Although everybody honores Nixdorf, the LK 3000 is only an
OEM Produkt, and Lexicon (whoever this is, no data) is the
original designer/manufacturer.

Also for the Dates, the Lexicon LK debuted in late 1978, While
the Nixdorf version has first been seen (in Germany) around
late 1979 (I checked some old magazines).

Lots of language modules, mainly English<->xxx and German<->xxx
(More English than German Modules have been availabel - I have
to take a look at some lists back home. Also two special informational
Modules for the Olympics (English), and a statistics package.

I have an unfinished project floating around to document the LK 3000...

AFAIR there has been something from Casio ... I'll have to check.

Jep, I would, a PDA is a bit more than a fixed (ROM) programmable
device. Also there have been other 'translator' type thingies.
