        Emphasize MECHANISM.  !ALL! electronics were Apple supplied, and
on the board over the power supply.  The ST506 mech was as much a ST506 as
a bigblock RAT motor is a full-ton pickup truck ... <B-)  BTW, the 10meg
was the ST412 mechanical (MUCH faster access than the 512, 85ms vs. 105ms
.. <B-) )

        (This is more for the lurkers than anything ... )
