The April 1979 issue of "Hewlett-Packard Journal" (published by HP) has an
article titled, "Cost-Effective Electronics for the Small-Business
Computer" that describes the HP 250 processor. It says, in part:

  "The heart of the system is a 16-bit NMOS processor manufactured by
   the HP NMOS facility at Loveland, Colorado. This is a hybrid chip
   set which is also used in other HP products, such as the desktop
   System 45."

That HPJ issue devoted seven articles (and the cover) to the HP 250.
