   I don't know what TERAK you have but mine has 32K of word addressable
   memory of which only 28K is really memory.  The rest are vectors.

   I am running IV.0 and re-compiling all my programs wouldn't be a problem.
   It would be more than offset by getting rid of a hog like IV.0 is on the
   TERAK.  After you load the O/S you end out with somewhere around 12K words
   but because of it being word addressed it really looks like much less to
   an application.

   Well they do make good door-stops.  :-)
   You want to buy some???  CHEAP???
