Sinclair QL SCART Lead Wiring

The Sinclair QL also provides a female 8 pin DIN for its monitor socket although the signals output by each pin are slightly different to the Spectrum 128. The pin-out configuration is shown below.

Sinclair QL Monitor Socket Pinout

1Composite PAL 1V pk-pk
20 Volts DC 0V
3Composite Mono Video1V pk-pk
4Composite Sync TTL
5Vertical Sync TTL
6Green TTL
7Red TTL
8Blue TTL

Sinclair QL RGB colour outputs require additional resistors, as does the composite sync signal. The circuitry required is shown below.
