Just my opinion, but this looks like exactly what it says it is, a
microprocessor-driven ePROM reader writer that allows a person to perform
some specialized functions related to altering the contents of an ePROM,
such as re-locating to a different memory space or similar edits before
writing a copy.  This is a peripheral device.  I would not call this a
computer, as in "general purpose stand-alone computer for convenient human
i/o, programming".  I have a similar 4040 (4004) programmer.  The
microprocessor takes the place of a lot of microcode ROMs, thus cheaper
than a similar unit without a microprocessor.

Maybe this is what everyone else has been already saying I have not read
every post in this thread.
