abbotkinneydude Posted June 15, 2015 Share Posted June 15, 2015 Interested. Would definitely buy more than one unit if professionally produced. Quote Link to comment Share on other sites More sharing options...
+Firedawg Posted June 15, 2015 Share Posted June 15, 2015 Thanks again Robin for your hard work on this project and the DIY 128/k/512k carts. You can count on my support of this project as well. Mike 1 Quote Link to comment Share on other sites More sharing options...
pirx Posted June 15, 2015 Share Posted June 15, 2015 Another issue is cart shells, getting some manufactured again adds to difficulty, making your own is probably even more difficult. Being a cart that needs an SD slot, it'd be difficult to adapt anything. Simple cart shells are easily available here: http://sklep.nikomp.com.pl/pl/p/OBK070PC-Obudowa-Z-7-906819mm-cartridge-czarna/3116 There are nicer shells available as well, but I have no addresses handy now.

flashjazzcat Posted June 15, 2015 Share Posted June 15, 2015 Meh... Flat files will do. Although that cart shell is the usual 1200XL-buster. 1 Quote Link to comment Share on other sites More sharing options...
adam242 Posted June 15, 2015 Share Posted June 15, 2015 Meh... Flat files will do. Although that cart shell is the usual 1200XL-buster. If it's the shell I think it is, it doesn't fit an 800, either. That would be a deal breaker for me. Quote Link to comment Share on other sites More sharing options...
electrotrains Posted June 15, 2015 Author Share Posted June 15, 2015 My aim is that this will fit in a standard (grey) cartridge shell. That means it will fit in all 400/800/XL/XE's. I was planning to file a slot in the top to provide access to the micro SD card. I did something like this when I made a case for my SIO2SD, and it turned out ok. However it would be nice not to have to destroy old cartridges to get the cases, so if anyone has any better ideas....? Robin Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted June 15, 2015 Share Posted June 15, 2015 IIRC, Steve Tucker has an injection mold to make the OSS type cart shells he uses for his carts. They fit 800s and 1200s fine. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted June 15, 2015 Share Posted June 15, 2015 I'm not sure if any discussions happened regarding licensing Steve's cart shells to third parties, but I'm assuming nothing ever gets off the ground there: hence the off-the-shelf generic parts.

Greg2600 Posted June 16, 2015 Share Posted June 16, 2015 I would be interested if the cart can play nearly all the games the IDE solutions can, and has an easy to navigate menu (sure it will). I don't even have an 8-bit but this could actually cause me to obtain one. Quote Link to comment Share on other sites More sharing options...

+remowilliams Posted June 19, 2015 Share Posted June 19, 2015 Sounds neat, I'd definitely be interested. Quote Link to comment Share on other sites More sharing options...
Defender II Posted June 30, 2015 Share Posted June 30, 2015 (edited) As long as they aren't too expensive, I'll take 2 if it fits the 800, and 1200XL. If you make it to fit the older brown atari cartridge cases in stead of the XE you can reuse BASIC cartridges which are easily obtainable.

electrotrains Posted July 8, 2015 Author Share Posted July 8, 2015 (edited) Dear all, A quick update on my SD Multicart project. I managed to design a PCB for the FPGA and to my suprise it actually more or less worked first time I plugged it into my Atari. This a prototype, rather than the finished article, so I can finish developing the software/VHDL. I will soon attempt a redesign to fit inside a cartridge shell. The new PCB has allowed me to make a start at cartridges that use the lower bank (I'd run out of IO pins on the development board), so I've now got the following types of cartridges working: - standard 8k and 16k ROMS (e.g. star raiders, pole position) - XEGS 32,64 and 128k ROMS (e.g.star raiders II, rescue on fractalas, airball) - Atarimax 8mbit (e.g. space harrier) - Bounty Bob Bounty Bob put up a bit of a fight - took me ages last night to get it working, but now seems to be running reliably using the ROM dump on the atarimania site. Does anybody have any SIC! cartridge images? That would be useful since I was planning to add support for them soon.

billysastard Posted July 8, 2015 Share Posted July 8, 2015 i have the sd2sio which is great but an sd based multicart would certainly be on my must buy list, depending on price of course Quote Link to comment Share on other sites More sharing options...
electrotrains Posted July 8, 2015 Author Share Posted July 8, 2015 The parts cost of these is likely to be around £40 (or $50). Maybe a bit less. The FPGAs are a newish product from Altera, and the only ones available at the moment are engineering samples at around £20 each. However it looks like the final versions will be available shortly for about £12 each. I may do a small run when I've got the final PCB designed, but beyond that I'm planning to post the schematics, PCB files and code so people can build themselves (and hopefully improve and extend the software long term).

Hyperboy Posted July 8, 2015 Share Posted July 8, 2015 I would definitely be interested in a couple from the "small run" batch if available please. Sent from my finger. Quote Link to comment Share on other sites More sharing options...
FULS Posted July 8, 2015 Share Posted July 8, 2015 Hi, Great news about "Bounty Bob". I will surely buy 2 (maybe 3) of these from your "small run" if made available. I am terrible at building projects. Thank You! Doug Quote Link to comment Share on other sites More sharing options...
