On the same note:  I read an article in this month's EDN (Electronic
Design News) that quoted an Apple employee as saying that one would
need a ROM upgrade for a Mac // to use system 7.0.  Is this true?
He based this upon the fact that the ROMs in the Mac //s are not
"32-bit clean."  I would guess that this would be necessary to
use virtual memory.  Now granted, V7.0 is vaporware (article guessed
3Q90, so, of course I am taking a wait-and-see attitude... but I don't
want to upgrade the ROMs and my drive if I don't have to.  Anyone want
to comment?
