The 8-24 card will indeed drive the 2-page monitor with 256 grays.
(At least my 8-24 GC does! :-)  I don't know which connector your old
cable has...when I bought my 2-page this summer, I got two cables, one
of which fits the old 2-page 16-gray card (has a little coax plug on
the COMPUTER end of the cable inside the D-connector shell), and one
of which fits the 8-24GC, with a normal D-15 connector.  I'm pretty
sure that 4 bits/pixel (16 grays) is the limit for the older card.

I agree- some applications really work best in 256 grays! And on the
big Apple 2-page screen, it's truly beautiful.
Good luck!
