The factory site has only the German language manual. Jeff, I e-
mailed you the English version. Also, the factory site does not have
the older DOS sofware available for download. Instead, it has the me
LX3 Windows software which is listed as working with the LX4000 v.8.0
but not the earlier LX4000 v.5.3.

Does anyone know of a site where the necessary DOS software can be
downloaded?
