  1. This is definitely a problem with a lot of these after market power supplies. Back when we were kids we hooked our consoles up to RF and composite (if you were lucky) TVs but now people are attaching these things through high quality upscalers to super big TVs and of course this shows up imperfections that we would never have noticed in the past. It doesn't seem to help that old school power supplies often were linear while most modern power supplies are switched. Switched PSUs are more efficient but often noisier but this doesn't matter on modern digital equipment as it's not so susceptible. I hope you can get this right, we're rolling out Coleco RGB mods for PAL and NTSC consoles soon and if there's any picture noise something like an OSSC is bound to show it up. Fingers crossed for you
  2. Just purchased a Lynx 2 and would very much like to own one of these flashcarts, please put me on the list thanks.
  3. Ok sure I'll let you know once I'm done transplanting the motherboard.
  4. Interesting thanks, so it's definitely some kind of piracy enabling device? Is it any good to anyone? I'm thinking of just buying a broken 800XL for the case and transplanting the motherboard back into that.
  5. Atari 410 Program Recorder cassette deck in box with PSU. Untested, average condition (see pictures below). There's some glue residue on the back where someone had applied some packing tape. I thought at first this was a bodge-job repair but having removed it this doesn't seem to be the case. Unwanted part of eBay purchase of Atari 800XL, yours for the cost of postage or free if you can make it to Lincoln and collect.

  6. I've had to shelve this for a day or two to work on other projects but I'll give that a go and report back.
  7. I can make out maybe 288..on the bottom chip.. top one looks like it might have been an S? atari-chips-zoomed by videogameperfection, on Flickr I'd be happy to trade this machine for a stock 800XL if it really is interesting to anyone.
  8. Oh, well that's definitely not something I need if I'm going the flashcart route anyway?
  9. If they've been replaced it's a neat job, these look like the originals... IMG_1249 by videogameperfection, on Flickr Here's the whole motherboard, for interest:- IMG_1248 by videogameperfection, on Flickr Maybe I should do that then and just cut off the wires. I suspect whatever mod this was is now obsolete anyway once I've added a VBXL and some kind of flashcart? Then again I don't want to destroy it if it's useful/of interest to anyone. Quite happy to pick up another 800XL on eBay and part with this one if it's in some way unusual/useful to anyone? Appreciate all the help anyway!
  10. Yeah this seems to be what I'm seeing. That seems likely. Setting it to either the first or second position makes the machine boot basic or self test (depending on the BASIC switch). Setting it to the third position (RAM) just gives a green screen, because I guess there's no OS in RAM Aww snap I only just put it back together
  11. Well they don't seem to be missing but I'm not sure how I could tell if they were original? If I wanted to return the machine to stock could I just lift those two chips off the expansion board and put them back in those two sockets?
  12. Got her back together but managed to break the wire to the green LED that had been added on top of the computer after all. It really was very short so I guess it was inevitable especially for someone clumsy like me (this is why I have subcontractors for soldering/modding work Still very much in the dark as to what this thing is. Looking at the 800XL motherboard it seems to fit in where the MMU normally lives, so some sort of RAM upgrade?
  13. All right, lets go exploring! So first of all lifting the lid on the Atari IMG_1243 by videogameperfection, on Flickr Well that doesn't show us much, guess we need to get that circuit shield lifted. I didn't realise the power LED was an after-market mod, that made dismantling the unit a bit harder since it couldn't be disconnected without resoldering and I suck at soldering. Anyway, after slicing my finger on the circuit shield (hope I wont need a tetanus shot) I got the thing disassembled. IMG_1244 by videogameperfection, on Flickr (sorry the picture's a bit dark). So it looks like this expansion board fits on the sockets on the motherboard there. I didn't think I managed to pull it out of the socket taking the computer to bits but I couldn't swear to it actually on further inspection it doesn't seem to sit in the socket all that securely, so I could definitely have pulled it out without realising. I don't see any markings on the little PCB indicating manufacturer etc. There's also one wire that goes to a leg on this chip. IMG_1245 by videogameperfection, on Flickr Here's one closer up with better lighting, you can see the numbers on the chips. Oddly it looks like the numbers on some of them have been deliberately removed:- IMG_1246 by videogameperfection, on Flickr So, anyone any clue what this is?
  14. Hi, I'm new to Atari 8 bit computers having grown up with C64 and Spectrums. I recently bought a bargain 800XL from eBay (yes, miracles do sometimes happen). I don't have any software yet but I was able to get the machine into self test mode (what a cool feature!) and it passes just fine. There seems to be some after-market mod on the system, can anyone tell me what it's for? Here's a picture of it:- IMG_0922 by videogameperfection, on Flickr There's three switches at the back. I tried flipping them but all that seems to happen is the machine boots to a blank screen. Does anyone have any idea what this might be? My intention with the machine is to RGB mod it using Lotharek's VBXE board and probably add a flash cart of some description too. Hopefully whatever this is won't interfere with that! Thanks in advance for any help
