I have a small collection of old consoles from Sega. Also have a few Saturns, but I've never used one as a CD player.

You can tap the internal digital audio and use the Saturn as a sort of transport:

I know of the Sony Playstation SCPH-1001 being used as a transport/dac, never a Sega tho.

Problem using them as a transport tho is aging, both of the laser and the mechanics.

The transmitter chips has a lot of pins that needs to be set at a logic level. It's just hardwired 1's and 0's.

Yes, if the laser assembly is any good.

All the pins marked with red must be connected to +5V, and all the pins marked with blue to GND.

Most of the pins determin the function of the chip or are inputs that will cause instability if they are left floating. They need to be connected to certain logic levels (1 or 0) to make the chip work in the desired way. In this case 1 = +5V and 0 = GND.

It's very basic digital circuit theory

From pin 26, it looks like. That's the S/Pdif output of the CS8406 chip.
Thanks killingbeans for the excellent link.

I think I understand your confusion now. You think the CS8406 is situated on the Saturn motherboard and is part of it's design, right? It's not. It's an additional chip that you'll have to build in to the Saturn in order to translate to S/PDIF.

What you need to to do is get hold of a CS8406 and interface it with either the TDA1386T or the PCM1710 on the Saturn motherboard, depending on the revision. This is done via pins 3, 9, 12, 13, 14 and 21. And then grab the s/PDIF output on pin 26 via the voltage divider show at the bottom.
