    atari 7800 RGB/Scart

    If you are getting it for the "better" picture quality then you would be better off saving money and AV modding a 7800 as it is not pure RGB but rather RGB from S-Video. You can find NTSC mod instructions here http://atariage.com/forums/topic/186254-atari-7800-s-video-mod-with-pics/ or for PAL here http://atariage.com/forums/topic/173828-7800-pal-b-composite-vout-scheme/ it does give a better picture then the Peritel machines too.
  2. Any regulated PSU that outputs 9V at least 500ma on a 3.5mm Jack positive tip will work. Radio Shack sell compatable ones for $15, you need Adaptaplug™ F Old Atari PSUs do have a smoothing cap and they are likely to be quite dry by now, so may end with hum bars.
  3. The middle east was all PAL (B if you want to use RF).
  4. I am after 3 or 4 working Atari 2600 machines (NTSC) they can just be console only, would prefer Jrs but will take anything, Also wanted the following loose cartridges Combat Warlords Adventure Pitfall Pitfall II Indy 500 Super Breakout Freeway
  5. Mainly. Will consider others if cheap.
  6. My top 10 1 - Pitfall 2 - Warlords 3 - Super Breakout 4 - Adventure 5 - Combat 6 - Indy 500 7 - Freeway 8 - Yars Revenge 9 - Centipede 10 - River Raid
  7. Look for a working Atari or Sears pong console, doesn't have to be in good condition, can be missing knobs, switches, case, etc. Want one to attempt to convert the thing to output a composite video signal. Thanks
  8. Thanks.It helped a lot. Postage is a killer but as USPS have a postage calculator it is easy to see what something should cost to post. Sending the basic unit should cost about $14 to send at most and not $20.
  9. As topic says roughly does the original pong console weigh in lbs/ozs? I trying to see if someone is gouging me for postage.
  10. Looking for two working of any of the following, 800XL, 65XE/130XE or XE Game System machines for use in a video game exhibition (one of the largest video game exhibitions in the world with over 150 playable games, nearly all of them on original hardware. It doesn't have to be perfect but has to work 100%. Also looking for Boulderdash / Rescue on the Fractalus cartridges, these can be loose, beat up, etc. Failing that any cheap and cheerful floppy drive replacement. My budget isn't wonderful but hit me with offers. Thanks
  11. The point isn:t to make the picture quality better, it is to be able to hook it up to any NTSC compatible monitor in the world. This question has been asked countless times and so far the only sensible solutions have been to use a RF demodulator but this adds cost and makes the picture quality worse it should be possible to use a piece of stripboard and $1 worth of components to get a composite video signal as it is on the Atari VCS. Outside of American and Canada it is near impossible to use the console as TVs in PAL land won't tune into NTSC RF signals, even other NTSC countries like Japan also won't tune in due to different frequencies used. There is one hard to read schematic floating around http://www.atarimuseum.com/videogames/dedicated/pong_schematic.gif From this it does look like you should be able to get some sort of video signal from R10 but the signal is going to need some work done to it to make it composite. I am trying to get a couple of cheap consoles to see if I can get composite video from it as I do want to hook one up to a projector.
