You stated that the majority of memory in your case was used for strings
for user I/O. In this case
it (may) be relatively simple to use an external serial flash for
storing strings. These
are easy to hook up to the spi port of the msp430 and work with dma.
You could
store a pointer to the string (location and length) in your code and use
a procedure call
to "play these" to the serial port for user I/O.
