  1. Usually it would be a regulator chip blown when the (correct) PSU is unregulated, although is there a regulator in the Jag? I really can't remember, been ages since I looked at the schematics!

     

    Don't use Nintendo PSUs by the way, they give out AC instead of DC!


  2. In December 1994, Atari announced that the Jaguar would be sold  through all 25 TOYS "R" US Inc. stores in Japan plus other outlets selected by its distributor and sales representative, MUMIN CORP.  Bundled with the excellent "Alien Vs. Predator" game, the system had localised manuals and instructions. This was a difficult territory for any western console to penetrate, and the Jaguar would ultimately sell in very small quantities.  Then again, how is the mighty Microsoft fairing out in Japan with X-Box these days?

     

    That from this page

     

    There are 145 stores now...wow, only 25 back then? Well, what is a reasonable amount to assume they would have had? 100 per store, maybe? That's only 2500, but of course there are many other outlets in Japan, so I guess 15,000 COULD indeed be a reasonable estimate.

     

    Jay, after posting a link to your website over here, your collection has received much praise! Feel free to drop in and say hi if you like, I'm sure your input on the topic would be much appreciated. Feel free to post a link to your website under the "collection pictures" section, too!

     

    p.s. I hope you don't mind me linking to your site in the thread. If you have any problems with that, contact me and I will of course remove it. Oh, glad to hear the ROMs are nice and safe! Yeah, that could well have been a bedspread :)


  3. Wow, great site you have there! Thanks for that.

     

    Slightly worried to see the ROMs sitting on the carpet for the photo though! And what is that white cloth you had them sitting on? Doesn't look very ESD friendly!

     

    Still, a really nice collection :)


  4. I was having a discussion with some friends on Japanese Jaguars. Some believed the system was never released over there, others proved that Toys 'r' Us were to stock it in all stores there. Some said they have seen Jaguars there, but assumed them to be imports.

     

    What is the real answer? Were systems exported from the US to Japan, or did they have their own systems? What did the boxes look like?


  5. DON'T just reheat the solder. This is lazy and sloppy, and ends up in dry joints. Always clean off the pad where possible with a desolder pump or desolder braid, then using good soldering practice resolder the component.

     

    Go for a good 60/40 fluxed solder, try to get 22swg if you can as its thinner and easier to use.


  6. First thing to do would be check the solder joints of the connector to the board. Redo them just in case. Check there's good continuity through the connector - do it by opening the system and joystick if necessary. Did the 7805s look like they were replacements? Perhaps not all models followed your diagram EXACTLY. ;)


  7. PLEASE throw away any cardboard boxes you are using NOW! EVEN those magazine ones you get from stationers. Cardboard has acid which attacks the inks and the paper itself, causing yellowing and other problems.

     

    Get down your local comic store and get some archival safe bags, and acid-free backing boards if you don't want spine roll. You can get an acid tester pen from the same store, if its a decent one.


  8. First, u using an official PSU? If not u could be damaging the machine!

     

    Replacement switches are easy to come by - myatari for one should stock the real deal, or get a replacement from your fave electronics store. IF its the switch.


  9. ok, you'll learn I usually recommend you don't use this stuff.

     

    DON'T use keyboard cleaner. Use potentiometer cleaner. Real keyboard cleaner is foaming, contains ammonia. That's no good. Contact cleaner is no good. Pots need to be lubricated, pot cleaner does this. DON'T use it for cleaning carts, just pots.

    or in europe...

    get it there ;)


  10. Don't mean to sound pessimistic, but there are lots of things to consider.

     

    Firstly, size. A 7800 and 5400 in one is bulky. Then there's component availability - several chips were custom chips. Sources aren't infinite.

     

    This involves having some incompatible hardware, so you may as well emulate.

     

    But the biggy - copyright. Don't forget Atari copyrights DO still exist, and I dunno how the holder would feel about people making things like this. Royalty payments would make the project expensive.

     

    Why is the paddle controller a problem? Its just a pot FFS! If you're making a system, make a pad as well. Don't go using PSX pads, the ports will cost you a fortune! Not to mention being sued by Sony ;)


  11. OK, I don't have a machine being in England, but would be happy to try and assist in any way. Give me an e-mail and we'll see what we can do. Do you have a scanner? A scan of the board would be handy, I have the schematics. The scan would help me show you what could've gone.

     

    Dan, why is your name familiar? That's gonna bug me now! lol


  12. That headphone bit would be where the PSU goes - a pretty important part of the system!

     

    9V DC 500mA REGULATED

     

    try eBay or myatari for genuine ones, or radio shack/mcmelectronics etc for a replacement.
