The Spanish ver, of ZX has a different RGB socket pin out.
The Spanish Spectrum 128 (Investronica) Model (2.1) also provides a female 8 pin DIN
(type 45326) for its RGB socket but the signals output by each pin are different.

The internal circuitry of the RGB socket is identical to that of the UK Spectrum 128
