For those interested, the guy at hobbyroms.com just got back to me via email, here is what he said:

"MKII uses 27c040 ( 4Mbits, 512K x 8bits )
You can also use 27c4001 which have the same pinout.

You should try to use speeds of 120nsec or faster,
although 150nsec will also work."
 
which revision number was the mk2 where cage had "johnny" written on his pants and one of barakas moves was the blade spin they gave back to him in mk trilogy? i'm guessing rev1.0 or something...there's clips of an early revision of mk2 featured on the history of mk thing on deadly alliance and also on the mk2 extras on mat2...this could be the same one...
Another question has that early mk2 been emulated?
there's an old issue of EGM from summer 93 with Tony Marquez Katalin Zamir Rich Divisio and Phil Ahn on the cover all in costume, this featured the early revision in depth... 8)
