The adapter can be connected directly to the TV with the male SCART connector. Another notable difference is that it has a female VGA input and two SCART outputs, one male and one female. The switches are more accessible so that the power supply or the aspect ratio of the screen can be changed without having to open the adapter. The appearance of the latter is quite different. This implementation looks almost identical to the original, except the position of the LEDs. UPDATE: I am happy to say I have found two stores selling implementations of this adapter.
The full circuit fits in a (big) DE-15 enclosure using a single sided PCB and easy to solder through-hole components.The basic circuit only requires the PIC and a pair of resistors and capacitors.Optional LEDs to test the power and input sync signals.Optional aspect ratio selection (16:9 or 4:3).It can be generated by the PIC itself as noted by Visenri. No external power source nor DC-DC converter is required to generate the 12V of the SCART status signal.Most VGA devices can provide enough power to the PIC so no external power source is required.Also, if any of the input sync signal is wrong then the PIC disables the the SCART RGB selection signal and the SCART status signal. This is useful if you are using it to generate the Csync signal of a very old arcade monitor to protect it. The PIC monitors the input signal and set the composite sync to ground if the frequency of the horizontal sync signal is wrong or if the vertical sync signal does not change.
As it stands now, I have a WG 25-inch monitor in my GT cabinet but it is needing replacement. Hello all, I'm hoping someone will be able to provide me with some assistance with my Golden Tee Complete setup.
