It sounds like a 170 upgraded with an Envisio Notebook Display Adapter
(NDA/30). The NDA/30 was an early add-on for the 140/170 which replaced
the expansion memory card with a card containing a video board and
memory.  The associated control panel would allow either video mirroring
or dual display. One downside, though, the NDA/30 was not compatible
with virtual memory or RAM Double, so no memory beyond what was the 2mb
on the motherboard and what was installed on the card.

FWIW, I *think* I have a spare 2mb version running around here
somewhere. If someone's really interested, I could check to see if I
still have it.
