You are not lost, there is a datasheet for the second one, which is
the actual display driver:

hah, and now I also found a likely candidate for the other chip, as in fact the NEC chip has 42 (!) pins, not 40, so this indicates a 75XL series microcontroller.

Maybe one day I'll learn counting at least...
