atarianer2003 Posted October 17, 2003 Share Posted October 17, 2003 Hi all, my 7800 only show picture in B/W. I've tried it with carts (Mario Bros. Choplifter, Sentinel) and with the built-in "Asteroids"-Game. The PS is non-Atari, it's from a third-party manufacturer. Output: 9V 550mA. Now I've opened the system: The IC Type "VLSI 9029AV 140792 VF2085B CO25718-30" was very warm after 2 minutes. Is this one defective? The board is a Rev.C. Board (ATARI CORP. REV C. C300633-001 - 4290 => Mfg. Date 2. April 1990?!?) On the RF-Modulator is a small sticker with "ARIEL" written. Or can anybody say, what could be wrong with my 7800?

+Mitch Posted October 17, 2003 Share Posted October 17, 2003 Do 2600 games display in color? 550 mA is low for the 7800, it's rated for 1000mA.That could be your problem. Mitch Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted October 17, 2003 Share Posted October 17, 2003 Mitch it right. Get a better Power supply. The 7800 NEEDs that 1amp goodness. If you put a lower amperage on it... they usually do display in black N white or will just scramble like mine usually does. Quote Link to comment Share on other sites More sharing options...
Classic Pac Posted October 17, 2003 Share Posted October 17, 2003 I agree get one that is at least 1 amp. What you want to do kill your system? It's like trying to run an NES DC power supply. Quote Link to comment Share on other sites More sharing options...
ussexplorer Posted October 18, 2003 Share Posted October 18, 2003 I read the part were you could use an atari 2600 power supply. So I did the 1/8" sterio mod. It seems to work just fine. Color and all... Am I crazy? laters..... Quote Link to comment Share on other sites More sharing options...

Classic Pac Posted October 20, 2003 Share Posted October 20, 2003 According to an old game mag from 1984. The 7800 US version was to have Pole Position 2 built-in Quote Link to comment Share on other sites More sharing options...

Unfortunately it never happened, unless there's a proto for it lurking out there somewhere. (Curt?) Mitch Quote Link to comment Share on other sites More sharing options...
