Those programs used very large buffers (16k+) to compress and decompress
things (which is a nice thing about the 86).  I was talking to Kirk Meyer
about this very subject and he was pretty sure that implementing the
compression algorithm from lite86 at least would not be feasible on the 83+.
The 83se, however, has those extra ram pages that could be used.
