1088XEL Alternative Mother-Board Project

I just figured out how to do a cut-away view in TinkerCad, and thought it might be interesting to post the result...

It's actually very easy to do. You make a block in whatever size that suits what you wish to cut-away, make it into a 'hole', move it over your model, and then group the entire thing.

So, do we have any feel at all about how much the finished product might cost?

 

Thanks!

 

Too early to know what the total cost would be for all of the components, since I still need to work up a BOM and then price the individual pieces out, but for the 4-layer PCB assuming you were to go with the standard set-up (1 oz copper, green solder mask, white silkscreen, and 1.6 mm thickness) it would be $17. To get that price, would only require an order of 5 pieces which is the smallest order accepted (total price = $86 for 5 pieces). And for an extra $8 for DHL shipping, you would get these in no more than 5 days. This was quoted through ALLPCB.com for the un-routed board, but with all power planes connected. I don't think the price will change much with the traces routed.

 

Actually the funny part is that the PCB will be one of the cheaper components in this project.

EDIT: Since you might have been referring to the Cart Tunnel cost, that is $30 from i.materialise to my door. Made from Polyamide (Dyed black).

I can't wait to see a finished unit. I'm dying to put one of these together myself.

 

You'll get your chance not too far down the road ;-) My intentions are to finish verification of form and fit within 1 week, and then start the trace routing. I'm thinking that'll take roughly 2 weeks in between other obligations, and then about 1 week following that to have the first run boards in my hands. Add another week or two for assembly and testing. So its looking like 5-6 weeks before preliminary release to a couple of beta testers. All together 2 months to final release to everyone.

 

By that time we should already have some beginning traction on setting up a pre-order and mass buy (that'll get handled by someone other than me).

I do believe I now have the PCB color adjust and oscillator sections all sorted out at this time :thumbsup: . I changed the color adjustment to an open frame trim pot which is a little bigger and also less expensive than what I had before. I also moved the primary oscillator section over to the left side with crystal X1 now being accessible even with a VBXE or Sophia board in place. Crystal X1 will also be socketed, thus allowing for a change from a PAL to NTSC crystal, or vice versa (the crystal socket can be made from a cut section of a machine pin DIP or SIP socket).

Sometimes I don't know my left from my right. On that previous post I meant to say "I also moved the primary oscillator section over to the right side with crystal X1 now being accessible".

So what we are seeing here is that this isn't a one size fits all situation. But with some adaption and the numerous choices that are available in Mini-ITX cases, it will certainly yeild some very interesting outcomes. Only limited by one's imagination. Welcome to the world of DIY.

That means I can still cross my fingers for a 1088XEL that looks likes this :grin:

I was thinking about a case like this:

although I'd have to rename it the 5200XL. :-D (No, I would never harm a working 5200, but there are plenty of dead/as-is models available on Ebay. Plus, GTIA/ANTIC/POKEY and probably more components could be used to populate the 1088XEL board.)

I see everyone is thinking outside of the 'box' ;)

 

I like what I'm seeing, and as I mentioned before it'll be very cool to see all of the variations to enclose this new motherboard. Lot's of choices for sure! I think my favorite for the moment is the one that Kavik posted (I'm in full agreement with Kyle on this one).

That is so friggin bad ass wicked looking :-o:thumbsup::thumbsup:

EDIT: It really would lend itself very well to the Mini-ITX motherboard form factor, with most all of the ports coming out the back. And since the joysticks have the flexibility to go anywhere, I think low and out the front would make sense for those.

See more of it here: Atari console concept

 

Very nice! Too bad it wasn't a reality :(

 

Speaking of reality... The trace routing has begun...

I got most of the bottom half done, but still need to route the chip selects and various handshake signals. The analog video section to the right is 98% complete, just missing the routing of the color signal up to the UAV and the RGB-THRU signals to the DIN-13 video connector on the back side. When I get everything electrically connected, then I'll go back in and tweak trace spacing and fine tune the paths.

 

I'll be ready for that cool looking Atari concept enclosure pretty soon ;)

Speaking of reality... as "bad" as it is, that thing would be a dust nightmare. I'd prefer something stylish, but practical too.

Meh - vacuum with a duster attachment or a can of compressed air. Surely you are not the type to not buy a gloss black car because it is hard to keep shiny?

I prefer satin, and it's not too gloss anyway. But that's not the issue, it's all those fins.

This quote is taken from the FPGA based Mini-ITX Clone topic...

Yes are there for the better support of pcb, and if you ask me, even those isn't enough! The 4 basic support holes are just to keep pcb in place.
The owner must add plastic spacers in bottom side, using a bolt in top. On the revised board I have add 9 more, especially near the IDC connectors who someone must press to fit. Support holes is a must against the bend of pcb, with any evil consequence can cause this!

I have read the thread of your excellent project for the Atari XL, and I propose to think seriously except the holes to go with 2mm pcb thickness.


--

 

I think santosp gives good advice with the idea of going with 2mm vs 1.6mm PCB board thickness. So I re-quoted with ALLPCB based on a 2mm board thickness this time. If the board quantity is moved from 5 to 10 pieces, it still yields a per board cost of just over $17 (this price includes the shipping charge). And I can also get my choice of color and lead-free as well... all for that same price. I had almost the exact same thing produced for another client a while back, and it looked great without any problems (except it was a 2-layer board).
