Swram is in 4,5,6,7 & your correct ROMS go into the cartridge slots 0,1,2,3 you could burn the ROMs & buy a cart to put them on, so Mouse could also exist if have two carts. if you can only get 6&7 swram, there is a jumper to make 4&5 too, it turns something else off, think the rom slot for a 32k ro...

I put the original 1.20 here many moons ago :

8272 what looks like a covered window as one might expect on an EPROM? Is the 8272 actually a micocontroller

it's probably just an earlier version of same FDC chip, but made prior to 1986, as the ones on two of my bare board 286 51/4" controllers has no 'window' & has Intel P8272A on them.
