  • Option A User port only.
  • Option B User and Analogue ports.
  • Option C User and Analogue ports and disc buffer to allow connection of additional, external, floppy disc drives.
The User port uses an R6522AP Peripheral Interface Adapter. The Analogue port uses an NEC D7002C Analog/Digital converter.
