The unexpanded Portfolio comes with 128Kb of RAM that can be partitioned
by the software between use as a RAM disk and as DOS "system" memory.
Since I tend to run mostly DOS software, I usually keep the RAMdisk small
to maximize the size of the TPA.  The people that exclusively use the
built-in applications favor larger RAMdisks.

There will be expansion memory modules for the Portfolio (although they are
not shipping yet) that will expand the memory in 256Kb blocks.  Each module
also has another memory card slot (card drive), for more flexibility with
memory cards. The modules pass the expansion bus through, so another
peripheral can be snapped on outside the expansion memory.

The Portfolio uses all surface mounted chips, as you would expect
in a unit this size.  There is no way to plug in more memory in the
base unit itself.
