Has anyone noticed that most SIMMs have 8 chips and a very few have 9?  The
obvious implication is that Apple doesn't believe in parity as a means for
detecting errors.  It would seem that particularly with 1 megabit DRAMS, the
probability of soft errors will start to become significant.  If the Macs are
targetted at commercial users as well as the home market, then some
robustness ought to be designed in.  I would hate to trust these beasts with
tens of thousands of dollars worth of data with no indication that it was
corrupted (other than La Bomba :-).

Opinions?  Anybody know if "no parity" holds true for the Mac II?
