	Before IC microprocessors were common, the term "microprocessor" was in rare use as a portmanteau of "[[microcode]] processor". Examples of this type of usage include [[BCC 500]], [[Maxc]], [[Xerox Alto\|Alto]], [[NORD-10]], [[International Business Machines\|IBM]]'s [[PALM]], and the processor in the [[DV11 Communications Multiplexer]].

The '''LX-1 microcprocessor''' developed at Lincoln Labs is an interesting case since it's ''also'' an integrated circuit.
