Connecting to one of the Cartridge slots on an expansion such as the Plus 1 or Slogger Plus 2, the AP34 floppy disk interface provides connectivity to one or more floppy drives.
Driver support comes in the way of either DFS (AP4) or ADFS (AP3) on ROM plugged into one of the slots inside the interface itself. There is provision to have both ROMs in place, thus creating the AP34.
My setup currently has either 2 x 3.5" drives or a 5.25" 40T floppy connected, and I recently added a double Cumana 40/80 T switchable 5.25" drive.
