@@stevemcknelly5036 Hello Steve, I didn't end up making a website per say. I did release the Gerber files and BOM for this board on github. Here is the link: github.com/Dan-Grise/2600_clone_pcb
Cool... I was thinking of doing a Linux type project at some point. On a different note, I am slowly putting something together on my homemade 6502 computer. Eventually I will have that up on the channel.
Magnus, you are absolutely right. When I "re-invent" some of these old systems it does help me to appreciate the original designers and connects me with the past.
@@dangrise6182 would be nice to go thru the entire catalog of Atari 7800 games with the goal of finding every address touched by those ROMs. with that knowledge proper address decoding could be implemented, that addressing would enable one to fill that unused space with SRAM.
I'd love to see information about that RIOT replacement board, I know the actual RIOT chips are still out there to be able to buy, but they're dwindling. The same for the TIA and the 6507. It would be awesome to have a modernish equivalent like this (probably use even less power, generate less heat, and probably more reliable), because like many others have ran into, buying replacements only to have them DOA, and it will come a time where you won't be able to buy them anymore.
You can probably substitute a plain 6502 for it's cut-down sibling (6507) either via an adapter or with a custom designed board. And much of the 6532's functionality is available in the 6522 (I/O and timers) even if modifying the original Atari ROM might be necessary to make that work. At some point you might as well just use a CPLD or an FPGA to replace all the chips though.
@@jnharton yeah, I believe FPGA is what they used for the pokey replacements (but I could be wrong), that's pretty much what I was getting at. They're getting to the point of being harder to find a good chip as many are just reclaimed junk and slapped onto the bay, and sometimes even other electronic component sites.
No, I have not made a case for the board. Some of the public libraries here have 3D printers and I've been meaning to check that out. I've been busy with other things... so I'll have to find the time.
Awesome video and awesome memories from my childhood! I remember I could play asteroid for hours without losing, it was kind of boring in the end but awesome at the same time! Thank you for the great video!
I am glad my video stirred up those childhood memories. I never got into Asteroids but I used to play my sister's Coleco table top Donkey Kong game for hours. All two levels of it. LOL.
This is awesome. You should consider doing a DIY top loading NES. I plan on studying enough to be able to put a Pi Pico, and NES together to create a "upgraded" and open NES. Right now way too ambitious for me.
The RIOT replacement module I designed might not fit in the actual ATARI 2600. The module is wider than the chip so in the ATARI it will probably interfere with cartridge connector. Also, my RIOT doesn't support the paddle... only joysticks... but even there, the CPLD on the module does not have built in pull up resistors so to get things working I opened a Sega Genesis controller and installed pull up resistors in there. For that reason I don't publicly share the design other than on Circuit Maker. I can email extra details if you are interested in making improvements to my design.
You are right. Pitfall, in particular, blew me away back in the day but the game I want most of all is Raiders of the Lost Ark. I had so much fun playing that at my friend's house as a kid.
This is amazing work. I looked at your Gerbers and BOM but am confused how the BOM is listed. Many of the part location only shows a specific location, but the qty seems to be double what you listed. Here's an example: 4.7k R2, R5 S4.7KCACT-ND qty=4. Assuming R2, R5 is for this part, but why 4? It goes all the way with a few components missing qty from the txt file. I think this would be a fun build and will attempt if you could clarify the BOM File. Thanks!
For things like resistors and capacitors I ordered extra. So in most cases the QTY refers to tge quantity I ordered. I can see now that this would cause some confusion. I'll try and look into this in the next little while.
@@dangrise6182 Thanks. Since you're confirming the location as the quantity on the BOM, it shouldn't be too hard to order the quantity I need. I appreciate the quick reply and will get an order in.
@@bioman1hazard607 I bought three different RIOT chips and none of them worked properly so I decided to make my own substitute. I am reluctant to release the schematic because my version won't fit into a real Atari 2600 and its function isn't 100 percent compatible with original. I am worried someone might build my RIOT board and be disappointed with the result.
@@dangrise6182 Hi Dan , great project. Inspired by your project, I would like to contact you to show my version. I am having the same component problem. I bought 10 RIOTs from different suppliers in China and only 2 worked. So, if possible, could you provide me with more information or help with how to implement the hardware in FPGA? I found the sources for Verilog from TIA and 6507 but there will be another story .... My email dognaldo@yahoo.com. Thanks.
Does anyone know how to turn a schematic into a gerber file? Thought about doing this project for a NES for myself. I like what Dan Grise did here with this build I'd probably do black PCB with white text though.
I know this comment is 2 years old, but if you're still interested - there is a clone NES motherboard called the OpenTendo out there, and you could probably go from there. But turning a schematic into a gerber requires mapping it out onto a PCB yourself, which can get complex!
Thank you. One day dream of mine was this. There is an update 2024 2600 schematic on Atariage by the gifted , " Kirkland ." Remember to buy him coffee.
I wonder too. Maybe I should create an adapter board and find out. The 6507 is rare these days. If a 6502 plus adapter works that would be a great thing as far as repairing old Atari 2600 units is concerned.
@@dangrise6182 That's what I'm thinking. I know they're software compatible because the 7800 has a 6502 and is backwards compatible. An adapter board would be great for repairs because they still make 6502s from what I understand.
@@dangrise6182 otherwise is there a way to provide backup power to ensure chip is loaded at pause state for long time periods? by example I wanna pause the game to continue next day
There might be a way of doing this... by blocking the clock from reaching the processor. While the processor isn't receiving its clock, it will effectively be paused.
I got my TIA from a company that sells old components for fixing arcade boards. The TIA chips were not new... they were classified as "chip pulls". In the two years since making this video the TIA chips are even more scarce.
that would be so nice ,if you want you can send me the files via email my email is warmachine38@web.de .i wanna build the Atari for a school project ( and for myself). greetings from germany :-) @@dangrise6182
