Resistor mod for all HYDRAs
Background:
some computers despite output RGB signal, do not output blanking signal to switch TV into RGB MODE (ZX+2, ZX+3, Amstrad 6128, 464...)
Modded hydra will be always expecting RGB signal with SYNC at SCART no1 INPUT. This port will be RGB ONLY.
No need for tricky cables and wirings.
