Genesis 1 RGB?

[NightSprinter]

So, I found out from Genesis at AllExperts that the Genesis 1 could output both RF as well as RGB through its AUX port. Does anyone know how this is possible for those who own a Commodore 1084S monitor and wish to get stereo out of it? Would love to know since I've two working Genesis 1 systems. Plus I'd like to know what the "EXT" port was supposed to be for.

The Genesis 1 A/V port only passes RGB, composite, and mono audio. To get stereo audio from a Genesis 1 you have to either mod the console and tap in to the line-level audio signals, or just pull the signal from the headphone port (I find the quality is quite good with the headphone turned up all the way, if you're worried about distortion then you might back it off just a tiny bit). For RGB, look here for pinout.

 

The EXT port was used in Japan for the MegaNet modem. To the system, it's just a third controller port with the opposite gender, so theoretically one could write a three-player game for an unmodified Genesis 1, all you'd need would be a single 9-pin straight-through gender changer.

Ah, so if I was to have a monitor like say the 1084S I could theoretically use the AUX connector for full RGB output?

If by AUX you mean the round "A/V OUT" port between the RF port and the power supply, then yes, just use the link I provided for pinout (the one on the left is the Genesis 1). As there are several different types of 1084 monitors (with different connectors), you'd have to disclose which kind of RGB port your 1084 has - whether it has 9-pin d-sub or two DIN RGB ports. But, you basically wire up the R, G, B, and sync lines to the proper lines on the 1084 side, and it should work unless either your Genesis or 1084 is faulty, or if you plain mess up with the cable.

 

If by AUX you mean the EXT port, then no, you can't, as the EXT port is just another controller port, electrically identical to the two on the front of the system.
