WANTED: 3b1 ram expansion

[Alex S. Crain]

	This summerizes the results of the last discussion we had on this, and
is all true. (What a statment :-))

	The 7300/3b1 are identical with regard to expansion limits, they differ
in the amount of memory that the come with.

	The 7300/3b1 is allowed 4meg memory. 2meg on the mother board (the 
7300 needs a mmu support to go from 512k->2meg, but it is available), and *one*
expansion card, which can be as large as 2meg, and must be in 512k increments.

	The 7300/3b1 has a 2.5meg limit on user addressable memory per process.
this is because of the way memory is mapped, the addressable user area is
bounded by the kernal (low memory) and the shared library/dynamic kernal memory
(high memory).
