Just a question - some people are claiming that as a result of its
32-bit dirty (?) ROMs, the SE/30 won't be able to take advantage of
virtual memory in System 7. Even the "dirty" addressing scheme allows
24 bits for addressing (which for various reasons probably amounts to
allowing 14M of clear address space). How many people need more than
this in the short term? How many people are going to have more than
10M to spare as swap space on their hard disk anyway?

Of course it's a problem, and Apple should be pressurized to fix it,
but it's not the amazingly urgent issue some seem to think it is.
