Be careful how you enable TERMPWR.  On some Sun workstations, TERMPWR is
*SHORTED* to ground.  This can, as you would expect, cause many problems;
including fried power supplies and motherboards.

Notably, the problems described occured here at Delta on our older
Sun-3/50 workstations.  I do not have any information on the newer
workstations.  The moral is, check pin 25 (TERMPWR) on your host adapter
connection, and if it is shorted to ground, do not allow TERMPWR to get
back to the Sun.
