RGB for ODYSSEY 2

[Sweersa]

I hear a good one costs around 350 USD.

is is possible to get an NTSC to PAL converter?

Yes, I've got a ComWorld KDV-1000. I think it's the same as the CMD-1200. I use it for my Odyssey2 and Odyssey3 consoles. I don't know exactly what I've paid for it, somewhere between $200 - $300.

Sorry to bump this old topic, but is there any more info out there on the Odyssey 2 RGB mod? This thread is basically the only info I can find on it anywhere. I would love to get my O2 going with some RGB. Thanks in advance.

There doesn't seem to be much info anywhere on modding an Odyssey 2, here is the place to go. We're it!

No picture but text
Yes, and it's actually not that difficult to do. Jay Tilton of Deathskull Laboratories first published the procedure. The Deathskull web site has unfortunately gone offline since then, but here are its original instructions:

   Materials Needed

     * [2] RCA jacks
     * wire

   Procedure

     Choose a place to mount the jacks. It's tempting to slap them somewhere
     on the back of the unit, but that would probably interfere with the
     Voice module. I drilled two holes in the side of the top half of the
     shell for mine.

     There's no point in producing schematics for this one.

       Audio output = junction of C45 and R49
       Video output = junction of C44 and R7

     One wire from each of the above points to the center post of an RCA
     jack, outside conductor of the RCA jacks to ground, badaboom badabing,
     away you go.

Thanks Seob that is some great info. Composite video will be a great upgrade over RF. Anybody know anything about RGB? The first post of this thread looks like he added some kind extra board for that. Any info on that?

The RGB output circuit has been copied from the Videopac G7200 console.
It's the circuit that is enclosed in the red line in the schematic below.

The signals of this circuit with the numbered red dots should be connected to the corresponding numbered red dots in the schematic of the Odyssey2 console below. For dots 5 and 6 an inverter should be inserted before connecting them (74LS04).

Seob, that old Deathskull MOD does work, but IMHO it is not worth it. I always got a dark and muddy looking pictures, and frankly refuse to crank up the brightness/contrast every time I play my O2. That is why I've always been on the lookout for a much better video MOD.

Awesome Rene. That is perfect. Much thanks.

I did this exactly but i only gen an greyscale picture. No colours.
Is it possible that console is damaged?

The Odyssey2 has NTSC video output.
Your TV is certainly PAL and doesn't accept NTSC video.
That's the reason why the screen is B/W.

- use another recent PAL TV
- use a RVB output (scart) see topic.

Thank you!
That was the hint i needed!

TV is supporting NTSC but the AV-Receiver not.
Plugging in the O2 directly on TV works fine.

For that reason i shouldn't work late night.
