[NTLK] Need help with finding chips for eMate memory upgrade boards

I finally found the time to open David's parcel that has been sitting next
to my workbench since January 10. More on this later.
Here's a scan of the EM300 board:
28F016SV is a 16-MBIT (1 MBIT x 16, 2 MBIT x 8) flash memory chip.
51W16165LTT6 is probably a RAM chip.
It would be cool if someone could locate
a) the datasheets of these two chips
b) a source that still sells them (very unlikely you'll find one, I'm
c) A chip that has more memory, but basically the same electrical
specification and the same timing specification. Such a component is likely
to have at least two more address line pins, which would not be a problem.
Would be cool, however, if the pins they have in common are at the same
place so that we wouldn't have to re-layout everything.
