You could get various expansions to page multiple roms, I had a machine at one point with 15 multiple internally and a zif socket on top. I think there was a board that sat across the 4 paged ROM sockets which then had a cable to another board with 16 sockets on it, and one of the 16 sockets came through the case in a ZIF. Aries or Dabs or Watford Electronics I expect. I also remember soldering switches to TEAC drives from RS to make them 40 / 80 track switchable. Duncan, your name looks mighty familiar .....
