**** beware... there were processors put together by hp employees from
scrap stuff at their house to play with... you will find parts from one and
all models sometimes kludged together!
used to run into this 15 -20 years ago when I would be in silicon valley
and then go out and hit some yard sales..... I imagine some of the kludges
are still floating around....
