Atari JagDuo PCB discovered!

Recommended Posts

I could be wrong on this since it was back in 2003 when I had one of the Jag Duo mockups in my hand. But the overall case was actually smaller in diameter than an actual Jag. So if the Duo PCB is wider, I have to assume the prototype duo mockup case wasn't a final design since being smaller, this PCB wouldn't have fit inside it.

Sadly, actually. For nostalgic sake it's kind of cool but definitely not fun to use and wish it upon no one. I've since painstakingly updated the BOM so it's easier to deal with in modern day form. Have already ordered the bulk of the major components and ICs. Next round is to order all the mundane but clearly very important resistor, capacitor and crystal stuff...

As long as the PCB fits the case drawings as intended then yes, definitely want to keep everything as close to the original prototype design as possible.

 

Some of the parts have started arriving. I was going to completely drop the RF altogether since it likely serves no purpose but they were surprisingly easy to find. So to stay true to the original design, I figured why not:

Have you thought about vacuum molding to . I wonder who  owns proto case

If this has already been asked? Apologies. But will this use the same "guts" as the current Jaguar or will it use different processors? Will the bugs that affected the current Jaguar be remedied? Just curious. 

 

Either way. If this does get made? I want one! Original CD systems are too cost prohibitive for me.

 

Good luck! 👍🤘

The prototype PCB itself could be larger than the case and one or the other might need to be modified slightly in the end but it does appear to line up perfectly with the side and rear from a layout standpoint. Since I don't have the case in hand or the exact dimensions, I'm unable to verify. Hoping to have the case design files and/or schematic drawings soon, its just been a waiting game.

 

Priority is still to have a single board built and proven to work before the rest is of any concern. The major components have mostly all trickled in now. Carefully going through and sourcing 100+ different parts has been very time consuming, especially since quite a few are obsolete and updated alternatives were required.

Yes, definitely an option. This is how the prototype headsets were created for the Jaguar VR.

When Atari moved from Toshiba to Motorola, they did not bother fixing the bugs you're referring to in their chipset that affect current Jaguars, although they could have. I'm guessing to remain completely compatible across the board and to prevent a recall on any older units, they decided to not update them. That is just speculation though.

 

These will use new old stock 2nd revision Motorola chips.

I stand corrected. Although there isn't a link to it from the site, I was able to locate AA's old gallery from my first OKGE I organized and hosted back in 2003. That was when the Jag Duo was shown in public. And I found a pic of it in the curio cabinet it was locked in along with other cool stuff. It is clearly wider than a normal jag as can be seen from the comparison with the other console shells in that case plus compared to the size of the controller port openings.

Sad it just disappeared, now that finally someone would do something with it aside from looking at it. Hope it resurfaces...

Tim is out there, he just seems to refuse to communicate for whatever reason. Possibly doesn't even own it anymore but if not, then no idea who does. The mechanical drawings will do just as well since it'll have the measurements.
