Here are the UltraLite specs as they are listed in an NEC FastFacts
document I spoke about a while back. Since some of these specs don't
seem to appear anywhere else in the UltraLite documentation, I went
ahead and transcribed it.

Just so you know, I faithfully transcribed the strange formatting,
odd sentence structures, and misspellings (note the "power combustion"
of the "ROM/RAM Card Slot"). You get both information *and* entertainment!
