This adapter board is compatible with the F18A MkI only (the revision with a 22-pin FFC output cable).

The adapter is compatible with the following PICO9918 accessories (not included):

• VGA Dongle
• HDMI AV Dongle (with audio): see Digital AV Dongle
• No-cut Kit (TI-99/4A): see TI-99 4A No-Cut Mod

• 1x fully assembled F18A to PICO9918 Dongle Adapter PCB
• 1x 5V power lead (only required for the HDMI dongle)
• 1x 120mm (5") PICO9918 FFC cable

• 200mm (8") PICO9918 FFC cable
• 300mm (12") PICO9918 FFC cable
• 200mm (8") F18A MkI FFC cable
• 300mm (12") F18A MkI FFC cable

The adapter has an FFC connector on each side:

• F18A side: connects to the F18A MkI's 22-pin FFC output cable.
• PICO9918 side: connects to a PICO9918 FFC cable (12-pin, 0.5mm pitch), which then plugs into your VGA dongle, HDMI dongle, or no-cut kit.

Two additional headers are broken out on the board:

Whether you need either of them depends on the accessory.

Both accessories are passive: they draw no 5V rail and have no audio pins, so the two FFC cables are the whole install and both extra headers are left alone.

The HDMI dongle adds the 5V lead, because its MS9288C encoder runs off the +5V on FFC pin 12 and nothing else here supplies it.

Audio is wired exactly as it is on a PICO9918: a 2-wire lead from a point on the host mainboard straight to the dongle's AUDIO IN/GND header. It does not go through the F18A or the adapter, so the adapter's AOUT/AGND pads are left unused. See Audio Wiring for the dongle end, and the per-machine tap points linked from there.

1. Connect the F18A MkI's 22-pin FFC output cable to the adapter's F18A-side FFC connector.
2. Connect the included (or an optional longer) PICO9918 FFC cable between the adapter's PICO9918-side FFC connector and your chosen accessory: VGA dongle, HDMI dongle, or no-cut kit.
3. If using the HDMI dongle, connect the supplied 5V power lead to the adapter's +5V/GND header. For audio, wire the dongle's AUDIO IN/GND header to a tap point on the host mainboard, the same as on a PICO9918. The adapter's AOUT/AGND pads are not used.
4. Power on your F18A-equipped system as usual.
