Subject: HELP! TTL Monochrome on C128D?? Yes? No? Maybe?

I recently purchased a used C128D at a conveniently low price (dirt cheap).
A friend has decided to upgrade to color on his IBM PC, and has an
extra green-screen monochrome TTL monitor that he'll let me use.

So, is there any way I can hook his TTL monitor to my C128D's RGBI port to
get an 80-column display? The monitor has a nine-pin IBM-compatible plug which
appears to have the same pin arrangement as my RGBI port, but plugging it in
directly doesn't work worth diddly. As I can't seem to find any useful
information about my RGBI port, I am having difficulty figuring out what the
heck could be the matter.

(And, to be able to play a game or two, I would also like to hook the
monitor up to the 40-column video port. Is this asking too much?)

Help! If you need more info on the monitor, ask!
