Getting true stereo from an Atari 2600
Submitted by SpongeBuell
For this project you will need the following things:
1. a small, flathead screwdriver and a regular phillips screwdriver
2. a pack or 1kohm resistors (radioshack cat. 271-1118)
3. a pack of .1uF capacitors (radioshack cat. 272-1069)
4. wire, solder, and a soldering iron (duh)
5. (optional) perf board for mounting (radioshack cat. 276-148)
Open up the 2600 and take off the RF shielding. Using a
small (non-magetic) screwdriver, pry out the stella chip. On the 4-switch
versions (and I believe the 6-switch ones), the stella is not soldered in, only
pressed into a socket type thing, which is soldered to the motherboard.
Find pins 12 and 13. Bend them outward so they do not go
back into the socket. This separates the 2 audio channels.
Push the stella back in the socket, but make sure it isn't upside down.
Now that you have the stella in place, power pins 12 and 13
with 5 volts and 2kohms (2 1kohm resistors) in between. Attach a .1 uF
capacitor to each pin, and your audio out wires to the capacitors. Now you have

My 2600 built into a dreamcast controller is finally done, started over a year
ago (some of you (Hi Ben!) saw the rough version at CGE2k1). Screen provided by
an RCA 2.5inch lcd tv, in fact it still works as a tv. Input/output jack so
2600 AV can be sent to an external tv or some other console can be displayed on
the LCD. Power supplied directly from 2 6v RC Nimh batteries, maybe 3 hours of
life between recharges. The standard 2600 3-chip schematic (minus regulator and
modulator) is handwired onto a breadboard.
