Not to drag this back up and muddy the waters further but...I just found an article from 2000 that states that the 780 RAM is upgradeable to 48MB...so the search continues.

Memory: 32 MB RAM (exp 48); 24MB ROM (upg)
Nevermind...reading an old thread about it here it seems the expansion to 48MB referred to in the article never actually materialized from NEC.
