Pin 24 is /OE, /CE is pin 22you can figure it out using a multimeter:
the 27c010/27c1001 (JEDEC)
CE = Pin 24
A16 = Pin 2
the 27c301/27c1000 (non-JEDEC)
CE = Pin 2
A16 = Pin 24
basically A16 should be shared between all of the ROMs in the same group, while CE will either be tied to ground or shared with only 1 other ROM.
In my experience on the System 16 ROM boards it either uses ALL 27c010 or ALL 27c301, I've not noticed any that are mixed.
