  1. Hi @manterola and @marauder666, Next time I have a similar project, I will make sure to have these items it my toolkit. Would have the job a whole lot easier! Thanks!
  2. I had started out by cut out a hole to accommodate the DVI plug for the Sophia 2. I started with some round drill holes and I figured I would use the dremel to shape the hole into a square instead doing by hand with a file. I ended up making the holes too large because the dremel sanded a lot better than I expected 😅.
  3. I looked back at the thread and took a look at the pictures. The composite video upgrade that seems to be discussed looks like a simple design that reminds me of the one that is sold for the Atari 2600. See this link for what I mean. With this solution , you may not get the best video signal out of your machine. The audio is probably being tapped from the leftover pin outs for the missing DIN connector. Someone else with more electronics experience can provide a more detail on the solutions provided here.
  4. Hueyjones70, Thanks! A lot of people here on Atari Age have been really helpful with their insight, guides and photos on their projects. It has really helped me with my own projects on my Atari computers. I hope this helps someone out with theirs!
  5. TemplarXB, Sure! I am not sure if needed the the photos the 64K memory upgrade as well, so I will post both just in case. There seem to be many variations on how to do the 64K upgrade for the 600XL. I chose the one that was the I felt that most easily reversible. Here is an overview of my 600XL with the UAV, 5 PIN DIN and 64K memory upgrade installed. The RF modulator has been removed: Here is a closeup of the 64K upgrade. I had removed the kapton tape that was on for insulation (I am still using my RF shield) I followed the guide that was posted here HOW TO UPGRADE YOUR ATARI 600XL TO 64K RAM: Here is the UAV upgrade. For the record, I did this upgrade before I did the memory upgrade because I had no way of knowing if my 600XL was functional since I had no display to connect to it. I very relieved to see my 600XL was alive when I hooked up to my TV!: Here is a side view of the UAV install: Here is a front view of the UAV install: Here is a view of the case cutout. I wish it came out more neat, but I guess it came out ok. I did slowly by hand. I had already ruined an Atari 800XL case using a dremel trying to do a cutout for the Sophia 2 upgrade. You can still see one of the cutout guide in pencil still on the case: If there are any questions, please let me know!
  6. Hi hueyjones70, I am not sure if you you have looked into this, but I have a 600XL in which I did the 64k upgrade and video upgrade (mine is a NTSC model that did not have the video or sound sound out). I opted to do the Ultimate Atari Video (UAV) upgrade instead. The Brewing Factory sells the upgrade. The connection points for the 5 pin DIN connector are still on the 600XL motherboard too. The connection for the sound out is still wired. I procured a 5 pin DIN connector that fit the motherboard and installed the UAV. I removed the RF modulator in the process and drilled a hole into the case to accommodate the DIN connector. In all, it worked out very well. If you need some photos what I did, I can post it. Hope this helps!
  7. Patjomki, I see what you are saying now. Hopefully there will be a solution to enable SIO sounds. I am happy there is modern replacement for the Pokey chip since it seems be more difficult (and more expensive) to get one these days if one needs to replace a defective one.
  8. I do not know if you are looking for a “fix” for the SIO sounds, @foft gave some insight on how to get it back in an earlier post on this thread. I am also eagerly waiting for mine to eventually ship to put it into my Sophia 2 and U1MB upgraded 800XL 😀.
  9. Also, from what I understand it may not be 100% with the keyboard setup of the 576NUC+
  10. Hi goya, You did not post any pictures of the keyboard switch. If you have one made by AWC, there are two variants of the AWC keyboards. One of them has the Cherry M8 and the other has a Futaba ML series (as mentioned by @_The Doctor__) which looks like a Cherry switch (see here). The one with the Futaba ML switch is keyboard type 2 (I happen to have this keyboard in one of my 800XL and and I cross referenced the part number on the PCB to this thread.) If yours uses Cherry switches, it would probably be a keyboard type 3 If you need some help identifying the correct switch, check here to see if there are any clues to the version you are looking for and possibly find an old keyboard that uses the same one for parts. Good luck!
  11. For those who do not know: Nintendo Targets Amazing C64 Port of Super Mario Bros. After 7 Years’ Development
  12. @Mclaneinc Very true! I linked this not necessarily for a port SMB. By studying the code, it may be possible to give someone insights on how things were done in that system in relation to the Atari 8 bit.
  13. I am not sure if this is helpful, but someone disassembled and posted 6502 source code for the actual NES Super Mario game. I am linking it here to see if this would be of interest to some of the programmers here. A Comprehensive Super Mario Bros. Disassembly
  14. Hey @massiverobot ! I just went and gave your Reddit post an upvote. Nice work! Good luck!
  15. @Stephen, No worries! 😁 I should have made it more clear too. I can see how it could be implied from the post.
  16. @flashjazzcat and @candle Thanks again for your time and information! I am not sure how or when I turned on that option on, but I am glad there is a resolution. I will run the new update as soon as I get an opportunity.
  17. @CharlieChaplin Yes, definitely! One can download an official SD card formatter from the SD Card association (both Mac and Windows). I actually needed to this to format a card so it would work on a Flashback portable as recommended in the Flashback forum. SD Memory Card Formatter
  18. It is in the manual. Page 61. "Use this setting for ‘difficult’ cartridge images which require the SIDE3 cartridge registers at $D5F0-FF to be completely disabled. Note that the only way to leave ‘hard emulation’ mode is via the cartridge reset button." when I saw this, it caught my attention.
  19. Interesting! Hopefully @flashjazzcat can give some insight on this.
  20. @Mazzspeed, I want to confirm we are talking about the same thing. The option I am talking about is a toggle in the side 3 loader options menu. It is called "Hard Emulation". As per the manual, "Use this setting for ‘difficult’ cartridge images which require the SIDE3 cartridge registers at $D5F0-FF to be completely disabled. Note that the only way to leave ‘hard emulation’ mode is via the cartridge reset button". It is not about the hard disk. This option can be toggled on or off and does not seem to require a reboot.
  21. Hi @Mazzspeed and @flashjazzcat I was reviewing the manual and the settings trying different things. So one thing that caught my eye was "Hard Emulation". On my system, it was alway on. I turned it off and guess what? The cartridges load with no issue! I was able to load PoP cart, Flob, Space Harrier, etc. @Mazzspeed: Could you try to see if this works for you too? @flashjazzcat: I guess this would explain why turning off the PBI Bios would work? Since it was off, it would also turn off hard emulation?
  22. @_The Doctor__ Correct! I never stated in my post that it was Atari who sued them. It was MOS Technologies/Commodore. It is quite interesting story. Here is an article on it in case anyone is interested. Reverse Engineering and Patent Protection: A Cautionary Tale
  23. Where in my post did I say it was Atari who doing was doing the suing?
  24. What is interesting about the NES is that it is actually using a 6502 clone running at the same speed as the Atari 8bit. They were able to get away without being sued because they only used the portions of the 6502 that was not copyrighted. In fact, I have read that the source code for Super Mario Bros is available online. Maybe studying this code would give certain insights?
  25. Hey @Faicuai! This is the thread I had read on the power consumption. It was was this thread that that guided me to get a power supply with a little more headroom when I started to get back into using my Atari 8-bit. Thanks for the link!
