  1. I was gifted an early 400 a couple of months ago. It also didn't power up. When I opened it, it had no plunger for the door interlock switch. I taped the switch down and it worked just fine. The keyboard ribbon cable had broken wires as well. I ordered a NOS 400 keyboard, an internal speaker and a door interlock switch plunger from Best Electronics.
  2. Just because the door is completely shut and you heard it click, doesn't mean that anything is actually making connection to the door interlock switch. It could be something as simple as a bad door interlock switch or a broken or missing door interlock switch plunger. From there it could get more involved and technical.
  3. I guess it could've been. I know that I received it as the club "newsletter" when I joined BRACE, Bluegrass Regional Atari Computer Enthusiasts, back in Kentucky in the early 90s. I think it definitely had strong ties to the Atari user group community, whether it started from MAM or some other.
  4. I'd be surprised if you could ever find any new, unless you lucked into someone that had a ton of NOS somewhere. I've seen a few of them on ebay though, typically reclaimed from old keyboards. https://www.ebay.com/itm/333703869469? At $4.95 a key, plus $4.45 for shipping, you probably wouldn't want to order too many though.
  5. I'd also posted over at Deskthority, a mechanical keyboard forum. Someone responded over there that they'd created a PCB in KiCAD using SKFL switches and they'd created their own footprint. If anyone else is interested, you can download the mod file here.
  6. What exactly is it a board for? I'm assuming, because of where you posted, that it's 8-bit related, and probably a computer motherboard, but you didn't really say. Which computer or device is the board for?
  7. It seems like every other day someone is coming up a with a new keyboard project. I've come up with another of my own. I have a type 1 ALPS mechanical keyboard in my original 800XL. The original cable was damaged beyond repair, so I tried adding my own connector, but the pads for the original 24-pin connector cable were unbelievably fragile; much more so than any pads I've ever tried desoldering in the past. Of the 24 pads, 10 of them lifted completely, most within a couple of seconds of applying the iron. I tried repairing, but it was in just too bad a shape. That being the case, I want to recreate the PCB and transfer the ALPS switches to a new PCB with newer, better traces. If I'm going to recreate the board, I'll probably have a 24 pin header like the original, but also bring to the side a 1mm molex connector as well, so that I can take advantage of newer, better cables. Here's where the trouble starts. I've looked and haven't had a lot of luck finding an ALPS switch model/footprint that I can use with KiCAD. Is anyone aware of there being one for the ALPS SKFL standard switches and where I may find it if it exists. If it doesn't, I'm going to need to try and create my own. In that case, is anyone aware of a detailed datasheet for the ALPS SKFL standard switches? I've not had any luck on that front either. Thanks to anyone that may be able to offer information.
  8. That was it. Thanks! I just stared downloading it, but it is unbelievably, horribly slow. At this rate, it may be done downloading this time tomorrow. I'll install it and try to start learning it then. EDIT: I switched to the European mirror. The Worldwide download site was moving at a whopping 16KB/sec. European was more like 20MB/sec. and it was done before I was even able to edit my post! It's funny how quickly we've all gotten soiled to crazy fast downloads.
  9. Before I spend a lot of time teaching myself to use KiCAD and trying to design a replacement PCB, is anyone aware of anyone else already having designed a new PCB for a Type 1 ALPS mechanical keyboard?
  10. I probably missed it, but what design program did you use for these, and is it free to download/use? It seems like I've seen most of the designers on here using a package that starts with a K, but the name escapes me at the moment. Thanks for all that you've done. These designs are looking awesome!
  11. Well, you're definitely in the right place for help. I'm sure you'll come up to speed quickly.
  12. Nothing to add on what some of those items are, but you mentioned SIO cables, which were never used with anything other than the 8-bit Atari line. So, it sounds like you have a mixture of things, and since those SIO cables are in there and they have nothing to do with the 16-bit line, some of those other items may be unrelated as well. Just something to keep in mind.
  13. Yes, I'll definitely grant you that. There's no way a discussion of the Atari 400 keyboard could be had without someone bringing up the long hours of typing in some BASIC program on it, which leads to a discussion of how it was easier with this BASIC or that one, and so on. Also, you guys are right, normal human discussions change and evolve as the conversation goes on, and that's normal. I was just surprised at how quickly and how greatly that thread got away from the original topic, at least for a while. I guess as long as computers in general, and Ataris specifically, are being discussed, there's only so far off-topic we can get. For what it's worth, it does look like the thread has come full circle and 400 keyboards are actually being discussed again. So, more on topic, since I've veered off. For those of you that have multiple video options, like I do in my 1088XEL, which do you find yourself falling back to and using the most and why?
  14. There's absolutely nothing fictitious about it. It started off as a thread about the Atari 400 keyboard and quickly devolved into page after page of people arguing about various versions of the BASIC programming language that had absolutely nothing whatsoever to do with the original thread in any way, shape or form. Someone there definitely needed to pipe in with some well placed stay on topic comments. But now I'm replying to your ridiculous reply and we're off-topic again, so I'm as guilty as anyone else.
  15. Do you ever take a break?! I hope you have as much success and interest as you did with Moon Patrol!
  16. You got that right! Look at the way the 400 membrane keyboard thread got completely and, in my opinion, rudely, hijacked onto a completely unrelated discussion. It was quite ridiculous in my humble opinion, but then, here I am going off-topic, so I'll get back to work now.
  17. Yes, that or have some sort of upscaler like an OSSC or other device.
  18. Yes, but I think it has already been mentioned at least once, if not several times, that there is no loss of legacy function with either of the aforementioned video upgrades. If installed correctly, the computer still retains all normal RF and composite video function if one wishes to use them for titles requiring artifacting. So, there was never any need to tell the user that he or she may lose any legacy functions, because this just isn't true, in any way, shape, or form. I have no idea what the poster had in mind when they made the comment about "have you ever used a VBXE before?", but that very well may be what they had in mind, because by making the comment that you will, or may lose legacy functions, it sounds like someone that isn't very familiar with the device, at least to me. If the post that the quoted was referring to the Sophia 2 and not the VBXE, I think they can be forgiven for their assumption because, again, this thread is supposed to be about the VBXE, not the Sophia 2, so I think it was an easy mistake to make. For what it's worth, I'd love to see some sort of NTSC artifact emulation in both the VBXE and the Sophia/Sophia 2. As an NTSC user, that would be awesome and would truly leave me with no need to ever drop back to RF or composite.
  19. I'm not really all that familiar with the non-STF 520s, so I'm not sure, but I'd bet it's probably some sort of RAM upgrade. That's really just a guess though. Once you power it up, you should run SysInfo and see what version of TOS it has and how much memory it has. That would tell you quite a bit.
  20. This is pretty much what I was thinking, but glad to have you guys confirm. I think most of the dishwasher methods I've read of, or seen videos for, were mylar keyboards, not mechanical. I'm still not sure I'd want to use that method for any keyboard. It works great for empty case shells, but I prefer a more hands on approach for keyboards. I think I'm going to order some DeoxIT and a small brush set similar to this: https://www.amazon.com/dp/B074LZ649V/ Thanks for the comments. I don't want to derail the variants thread anymore than I already have.
  21. He did! Three of them! The 1088XEL, the 1088XLD, and the 576NUC+. Of course, I think you meant more along the lines of a new A8 with built-in mechanical keyboard and all-in-one 70s-90s case styling.
  22. I think the VBXE is an awesome upgrade, if a little unsupported. That certainly isn't @candle or @lotharek's fault though. The only issue I ever had was no NTSC palette. @flashjazzcat has now fixed this for machines that also have the U1MB. I have the VBXE installed in my 1088XEL, so I'll be happy. I appreciate everyone's efforts in creating and selling the VBXE and getting the old NTSC issue fixed, at least for me. Thank you all!
  23. Oh, trust me, I know. I was in on a lot of those discussions, at least the later ones. I wanted to pickup a VBXE for use in my 1088XEL, but didn't want to get it until I knew I could easily get an NTSC core working. I'm pretty sure there were earlier threads related to this topic as well, that go back even further. This is just the most recent one, and the one that finally led to someone actually doing something about it.
  24. Assuming you have an U1MB in the machine you install the VBXE in, there is, or should soon be, an option to select an NTSC palette for use with the VBXE. @flashjazzcat got it working a few months ago, but I can't say for certain if it has finally made it into the live versions of the U1MB firmware. Since it has been several months ago, I would think that it has, but I can't confirm. Hopefully, someone else can. There is an extensive thread here, detailing the quest for an NTSC palette for the VBXE: NTSC Core for VBXE
  25. I don't believe there are too many purists that would want to use a board like this, so there probably won't be too many concerned with using a different PSU. That being said, I think it would be best to use something that isn't physically compatible with any other available Atari PSU type, so as not to accidentally plug-in, say, the 9VAC barrel-style PSU from the 400/800/1200XL/1050.
