Bally/astrocade -> No Rf Video

[Komb']

I was told this site would be the place to ask/look. So here goes.

Currently, there are 2 circuts that are suposed to produce Composite video from a Bally/Astrocade. However all recent attempts using these circuts only produced monocrome video.

see:

(Part of the Bally/Astrocade FAQ)

As noted, there are Y R-Y B-Y lines there, so hooking up to a 'component' video system should be possable, however I can't afford one of those right now.

What I'd really like to do is make either (or both) colour composite and/or S-Video adaptors for this system.

If anyone wants a challange, or can point me at relivent information, it would be appreciated.

Thanks
