  1. MT RAM is definitely used in a lot more machines than just a 65XE. I think it was used a lot in all XL/XE machines. I have at least one 800XL with MT RAM.
  2. Is there no one selling these in the U.S.? I know Marlin sells Ultimate Carts through his Brewing Academy. I thought that Gavin was selling AVG Cart through his Vintage Computer Center, but I can't seem to find them on his site. I could've sworn there was someone selling them on this side of the pond, but now that I look, I can't seem to find them anywhere.
  3. I’m pretty sure they’ve both been out for a while now.
  4. Here's some more pictures of my 400, including the imprint. It looks like it says 9 49 6845. Depending on how the composite mod looks, I may remove that and put in a Super Color CPU Card. That is a pretty non-invasive, easy to remove upgrade. The same goes for TF_HH's 48/52K RAM Card if it still only has 16k. Both of those are easy ways to upgrade it, but still leaving it easy to get back to stock if I wish. She definitely needs a good and thorough cleaning and I may try to find something to patch that whole in front of the spacebar, so that it's not quite so noticeable.
  5. Thanks for the info! That’s cool to have such an early machine! I really can’t tell you much about it yet. I plan to clean and restore it as much as I can over the winter, but won’t have a chance to do much with it for at least a couple of weeks. It didn’t come with a power supply. I know I could use one from my 1050, but it’s packed away at the moment and I don’t feel like digging for it just now. I ordered an original 400/800 PSU that should be here Monday. I’ll test out the basics after that arrives. I’ll let you guys know what I find out.
  6. Well, mine wound up being a different 400, so the person that gifted me mine must have another one from the one he posted here earlier. It's pretty dirty and has a fairly small hole, possibly drilled, but I think it's chipped, at the very edge of the top case and the keyboard, under the spacebar about at the lower left corner of the M key. Oh, and the hatchet job for a composite video/audio mod in the back of the case. I have an authentic power supply coming Monday and then she just needs a good, deep cleaning. My new 400's serial number is hand-written, 9496845 and I guess the WW012/018 is what you guys are calling the date code. Is there anyone here that can help me interpret it? Thanks guys!
  7. Better yet, just use the link tool and make the text say crazy auction.
  8. I wanted to keep mine as close to stock as I could, so I soldered my socket on top of the CD4050 and only removed the channel switch, but not the modulator. That way the RF modulator still works, albeit only on one channel; 3 I think. It's really only an academic consideration, not a practical one, as I can't imagine I'll ever really use it again.
  9. I just pull mine from the monitor port. Of course, I removed the channel selector switch and added the monitor port when I upgraded the video with a UAV. There were only a couple of wires I had to solder. I can't recall if audio was being pulled from somewhere else on the board, or if it was just coming from the monitor port traces/pads that are still on the motherboard underneath the channel selector switch. You do realize that everything for the monitor port, except for the actual monitor port; traces, pads, everything, are actually still on the NTSC 600XL motherboard, underneath the channel selector switch, right? I'll try to check my documentation later and confirm. EDIT: I found this. Hopefully, Marlin won't mind me posting it here for your reference. If you don't like that spot for some reason, I guess you could follow that trace back to another spot or component further back and patch it in there.
  10. I missed that last comment. Is it OK to have both? Sure, but to be completely honest, it's a complete waste of money. The AVG cart can do everything that the Ultimate Cart can do, and much more. There is absolutely nothing that the Ultimate Cart can do that the AVG Cart can't. And this is coming from a proud Ultimate Cart owner. I love mine. When I bought it almost three years ago, it was, hands down, the best multi-cart out there. It emulated more cartridge types than any other multi-cart and was much better in that respect than the AVG Cart, which came out a year or so after I bought my UC. Step forward 2+ years though and there has been almost zero development or improvement with the UC and almost non-stop development with the AVG Cart. It has by far surpassed the Ultimate Cart in terms of features and the number of cartridge types that it will emulate. My UC still does exactly what I need to it to do, and with @flashjazzcat's menu system, I love it, but if I were going to buy a multi-cart anytime from about a year ago on, there's no way I would've considered anything other than the AVG Cart. It's cheaper to boot. In my opinion, the only thing the UC has over the AVG is a much nicer, better looking menu system, but that's more aesthetics than actual function.
  11. I'm pretty sure The Ultimate Cart will run rom files, but I'm not sure about the AVG Cart. Either way, it isn't a good idea to run rom files anyway. Even if it works, the cart is making it's best guess as to what cartridge type the rom file is, and it may not always guess correctly. A car file is just a rom file with a few extra byte header telling the multi-cart/emulator/whatever, what type of cartridge the rom file is from and how to use it. There are plenty of places to download proper car versions of pretty much every 8-bit cart ever made. You can also easily make them yourself from your rom files using a simple html tool. You select what cartridge type the rom file is from a list and then it adds the correct header information and saves is as a car file. I'd have to look for that utility to tell you where to get it, as I don't recall now where I got it. Honestly though, your best bet is to just download Mr Robots Cartridge Collection from here. There may be a few rom files in there, but if there are, there are very few. Almost all of these are proper car files, and that's really what you should be using with an Ultimate Cart or an AVG Cart. As far as converting atr or cas files to xex, I'm not sure. I think it can be done, but I'm not sure how. I'm fairly certain you can't make a rom or car file out of them because they didn't come from a cartridge. I've seen some pretty wild things on here though, so I could be wrong about that. Good luck Ray.
  12. Luckily, they look like a pretty easy card to put together. Of course, anything seems easy after assembling a 1088XEL or XLD motherboard! I look forward to watching the progress.
  13. Beautiful machine. I hope to get mine cleaned up and looking this good, other than the hacked up hole in the back of the case, of course. I thought I'd heard rumors of a 400 Incognito under development, and I've been Googling for info, but haven't had a lot of luck. I checked Lotharek's site too, thinking that would be the logical place to find info but, unless I missed it, there isn't anything there either. I did see a page for Incognito 2 under development, but there was no info at all, so I'm not sure if that's it or not. Do you have any links for info on the 400 Incognito, or is there just no info out there yet, other than the fact that it's development was announced? Thanks.
  14. I'll have to keep that in mind. I'm sure there are far more games than I remember that use artifacting, but I don't recall seeing it all that much in the games I typically played. Also, I don't use CRT monitors or TVs, so it's kind of a moot point either way.
  15. It's not from ebay, and I didn't buy it, but I'll be receiving an Atari 400 this weekend. I never even thought I wanted one, but this one was gifted to me completely free. I didn't even pay for shipping. Now that it's on the way, I'm super excited about it. I was told that it works, and from the looks of the hatchet job on the back of the case, it looks to be composite video/audio modded. I'll probably clean it up really well and replace the composite mod with a Super Color CPU Card and install a 48/52K RAM Card and that'll probably be it.
  16. I have a 400 coming that should be delivered Saturday afternoon or Monday. I hadn't really thought that I wanted one, but then this one just sort of fell into my lap, and now that it has, I'm super excited about it. I just made a stray comment on a thread about not being able to pickup a free one because it was too far away and a super-nice fellow AA member just offered to send me one. How could I refuse? My first computer was an 800 and I moved on to an 800XL in college, which I still have, but I only ever ran across one 400 out in the wild. A high school friend had one. I love the look of the keyboard and that retro-70s-futuristic look it has. It looks sort of like something you'd see on a base in the Aliens universe. I'm excited to get it and add its serial number to the growing list here. The fellow AA member who gave it to me sent me some pictures. I'm pretty sure he said that it worked well, but that it was just in OK shape and he thought it was composite modded. From the pictures, the keyboard looks to be in pretty good shape. All in all, it's just a little dirty. It needs a really good deep cleaning and hopefully not a whole lot more. The rear picture did show two RCA jacks showing through a square hole in the back of the case. It looks like someone enlarged the original RF cable hole for their composite mod. I'm assuming the second RCA jack is an audio output. It's not the best case mod I've seen, but I guess it could've been a lot worse and, luckily, it's on the rear. If it's working well, I'll probably just clean it up really well and possibly install @tf_hh's Super Color CPU Card and 48/52k RAM Card. EDIT: Actually, when I look back through this thread, I see that the member I'm getting it from already added one about three years ago. I'm assuming it is the same one I'm getting, but maybe not. Thanks again @adamchevy!
  17. Hey @Zeptari1, I'm glad you found the old girl a new home. I'm glad I posted about it too, because now I'm getting one, thanks to @adamchevy! What a great bunch we AA members are!
  18. I'd be worried about backwards compatibility with all those "extras", but holy crapola, what a beautifully upgraded machine! This is one of those do it because you can, not because you need it, instances. Thanks for sharing!
  19. How in the world did a thread about the Atari 400 membrane keyboard get hijacked into a discussion about various BASICs?
  20. I believe what you're referring to is the original RF signal, not the composite signal. When you install the UAV, you remove the 4050 chip and replace it with the UAV. This improves the original composite signal and also give you S-Video, but you lose the original RF output. However, if you piggyback the UAV on top of the 4050 chip, rather than replacing it, you will keep the original RF output. No, it does not. It improves the original composite signal and also gives you an S-Video output.
  21. Wow! That just goes to show why we AA members are the best. I'll have to find a way to pay it forward in the future. Thank you very much!
  22. See if you can get an idea what shipping to Evansville, IN would run me. What condition is she in? Running? Thanks for considering.
  23. That's a shame. I'd love to give this classic a good home, but I'm way too far away to even consider. I'm sure you'll find someone that'll give her a good home though.
  24. So, pads 1, 10, 12, 13, 14, 15 & 19 have all at least partially lifted. Seeing as there is no through-hole barrel and these were just surface pads, I really shouldn't be so surprised. Still, I was really surprised by the sheer number of pads that lifted. I haven't had this much trouble in all of the time I've been repairing boards. Looking at pad 19, the one that lifted completely off the board, as near as I can tell, it isn't even connected to anything, so I'm really not sure what that one's even for. Do any of the rest of you see anything I don't? Is pad 19 connected to anything?
