DdAzZ Bedankt voor het meedenken maar er is niets vreemds te zien bij pin 41
Ben gaan zoeken wat de "Hybrid Chip" doet in een Amiga en dat kan verklaren waarom monochroom wel zou kunnen werken en RGB analoog niet:
The Video Hybrid has 5 sections, one for each of the red, green and blue colors, one for the synchronization signal and one for a composite monochrome signal.
The red, green and blue sections are identical: first, the digital signals are mixed together using the typical binary-weighted resistors DAC configuration. After that, the level of the resulting signal is amplified through an NPN transistor. At the output, the signal is terminated at 75 ohms, as is typical for video signals.
The composite signal is generated in a similar way. The only significant differences are that the weighting resistors have different values and that the amplifier has two stages (NPN + PNP), in order to achieve a higher gain.
