  1. I'm hoping someone here can help me. I apologize if this has been asked elsewhere but I wasn't able to find it. Cleaning out my garage I found an old 1200 XL in the styrofoam from my father-in-law. I plugged it in and tried to turn it on and got nothing, no lights no nothing. Pulled out the multimeter stuck it on the Atari end of the power supply ... nothing. So my questions for you all are #1 is there anything I can do to try to fix the original power supply, I'm fairly comfortable tinkering with electronics/soldering etc. #2 if the answer to number 1 is nope, will this one work? 9v 2a guitar pedal psus on amazon Any help at all would be greatly appreciated , if you need any more additional information please let me know 🙂 Here are some pictures of the original Power Supply if that helps :

    Wanted: 1200xl

    Looking to buy outright(wed decide on the price) or trade+cash my 800 computer for an Atari 1200xl. Message me if interested. The 800 is maxed out for ram, overall decent condition for something 40 years old too, and works great.
  3. I am digging out some of the rare stuff in my collection (after 20+ years of storage) and wondering what the value on some of them are... Specifically, here's an Atari 1200 prototype unit. I haven't tried to turn it on, but it worked years ago when I last powered it up. I have a couple of 8-bit prototypes, 5200 prototypes, and quite a few 2600 prototypes I'll be asking about soon, too! Thanks for your help...

  5. I decided to fire up a 1200XL I bought years ago, and it doesn't work right. I can get into the memory test, and it completes it fine. Nothing else works, I get gibberish on screen right before it locks up. Attached is a screen shot when I first turn it on with nothing attached before it goes into the hardware test. Where should I start?
  6. Hey guys, I'm new here, but I recently saved a load of stuff from the garbage. A lot of this stuff I have no idea on the value, so I'm posting it here in hopes that people will find it interesting and make fair offers. I don't expect to get "ebay prices", I'd just like this to go to people who will enjoy it. Pictures are below. I realize most of them are inadequate, so if you'd like to see something in more detail, let me know and I'll post more pictures! I ship from Provo, UT. Local pickup is totally acceptable! Not pictured: 7x 1541 Commodore disk drives. Probably not worth their shipping weight, but if you can think of something let me know!
  7. If anyone has one they are willing to sell, please drop me a line. I haven't had much luck getting mine working. Everything seemed to be ok for a little while. 1UMB working correctly. Now I'm stuck with a dark-green screen upon startup. Nothing seems to change that. So I'm opting for a pre-built one if someone is willing to part with it. The more upgrades the better. Frank ------------------------------------------------------------------------------ UPDATE: I took my U1MB out of my 1200XL and put it in an 800xl. It worked fine. I reflashed it back to original (I had upgraded to the latest BIOS). Booted back up, was working normal. Plugged in back into my 1200XL and it started working fine. I think I'll wait on the new BIOS for the 1200XL's right now.
  8. Atari 1200xl up on eBay right now - item number is 322247199548 What is the box worth?
  9. Good morning, everyone, I'm finally brushed up on my soldering and desoldering (practicing off an obsolete 1027 mainboard), and am gathering the components I'll need to incorporate the ClearPic 2002 mod in my new family of 1200XLs. However, I'm already stumped and am hoping for assistance. For the resistors (1, 47, 75, 130, and 1k ohms) it appears that wattage plays a role in choice, yet that seems to be the most elusive bit of information for me after searching the forum as well as Google. I'm seeing anything from 1/4w up to 10w choices, but nothing at what I thought is the wattage of the 1200XL mainboard: 5v. Am I just looking for the wrong thing entirely? Thank you, in advance! Tim
  10. Hoping someone can advise. Got a 1200XL and Indus GT from America, and realise that you can't just plug these in and go.... not unless I want my 8-bit shenanigans to be all smoke-based. My understanding is that for the Indus GT a 5200 PSU should work - these are 9V. But other reports suggest 12v DC +. If the 9v 5200 PSU is suitable, what about a std 1050 PSU? So question is: to make both a 1200XL and an Indus GT work in the UK, which PSUs/adapters are the best to buy, and from where? thanks
  11. Hey all - I had a great opportunity to pick up some Atari 8-bit stuff last weekend for really cheap at a convention. I scored an Atari 800 (48k) with what appears to be the original shipping box (including foam inserts for the side of the machine), a 1200XL that seems to be heavily modified, and external keyboard for the 1200XL (keep reading...), 5 floppy disk drives (goodness), a sealed Donkey Kong, and a few other odds and ends. I was lucky to get all of this, and my only experience with 8-bit Atari computers was with games via the XEGS about a decade ago. I happily dug out Centipede, Megamania, and some others to fire up the 800. Gorgeous. That system has been cleaned and is waiting reassembly after everything is dry. Now then - this 1200XL. Several things about this guy. First of all, there is a DB-25 port on the front left side to connect an external keyboard. The bottom of the machine denotes the following mods in Sharpie - "FEHR Video Mod+" and "320k Mod - Lawless." Included was what looks to be a homemade external keyboard of sorts. It is a rather industrial-looking keyboard from somewhere (where?) that has been screwed into the bottom shell of a 600XL. It is so...weird. I chatted a lot with the seller about various things, but I didn't ask about the keyboard. Now I am intrigued. The 6 key is taped on with that green tape. The post-it on the 1200XL states "External keyboard does not work. video issues" I have been around the block many times with soldering, modding, etc., with numerous gaming systems. I have no experience or knowledge of what is out there as far as Atari 8-bit computer mods. So I look forward to cracking this 1200XL and keyboard open to see what the heck is going on. I plan to do it as soon as I get the 800 put back together and off the workbench. Can you guys offer any knowledge or opinions on this stuff - Where does that keyboard come from? What are your thoughts on the 1200XL mods that were mentioned? Apparently the video mod is having issues - so I have to either fix it or reverse it/change it for another mod. I know the built-in keyboard for the 1200XL tends to have issues, but I would prefer to just fix it (I saw a method for that in one of the threads here) than mess with this external thing - nevertheless, it sure it weird/interesting.
  12. Does anyone make or know of an expander (extension) for the cartridge port on the Atari 1200XL? Some cartridges I have just don't fit right in that slot. I know they're available for several other computer brands, but I don't recall seeing any for Atari 8-bits.
