The 80 pin diagnostic slot offers nearly the same signals as the A500’s side expansion connector, it is meant for any type of expansion device.
The 30 pin expansion slot can be used for DMA expansions, e.g. SCSI controllers.
The proprietary memory card slot (40 pins) takes memory cards of 64 kB or 256 kB size. These cards can be used as RAM expansion or flash memory; the content is battery backed up.
The 30 pin Video Slot is occupied by the video module, but this unit can be replaced by other expansion devices.

All the video connectors (except the RGB port) belong to a removable video module, thus enabling different configurations for different countries. The module is much the same like an internal A520.
The floppy drive controller supports up to four external devices.
The CD-ROM interface is a crippled SCSI-I connector and needs a special CD-ROM drive connected to it.
The MIDI ports are a part of the standard serial port circuitry. The CDTV can use either a serial device or a MIDI device, but not both at the same time.
