 the board can handle a single 27128  or a dual 27128  for standard rom images
 or you can use a single or dual 27256 and put 2 single or dual rom images and switch between the 2
 or you can use a single or dual 27512 and put up to 4 single or dual rom images  and switch between the 4
 the board pictured has dual 27512's
 or if you are asking about the size of the board , it is about 2in x 2in
 I wanted to go with a 27801 but I could not find enough cartridge images to make it worth the effort
 now if I could only find the info on the external memory board , I would make a batch of them to
