  1. Hi, I'm looking for a genuine Atari C25953-20 EMMU So I can upgrade my 65XE to 130XE (128kb RAM) Preferably UK based seller.
  2. thanks! exactly what I was after! This confirms my initial findings and actually makes sense... The 65xe goes up to 128kb only, that was always the plan. It's the 800xe that's getting 320kb so no issues here. Thank you again, I think I am all sorted now!
  3. all right everyone, I think I have everything in hand now. Thank you all for all your posts, it's been a pleasure reading and learning. One of my ataris - the 800XE will have the 320kb expansion as it will then do everything I require of it to do. It's got he 16 banks, 8 are filled and 8 empty so there's plenty of documentation and I have now been offered GAL chips to sort it out so that's easy. The other atari, which is a 65XE, has the 130XE board with only 4 slots, 2 filled and 2 chips are missing. I will have the GAL chip to serve as the memory management, but my question is, what 2 DRAM module do I need to get that will fit? it looks like I don't even need to but the capacitors or anything else as everything's in place. All the documentation and tutorials seem to be for the 8 bank version but can't find a straight answer on what DRAM chips to get if I only have the 2 slots. Initially I though I know exactly what I need but the more I read the internet the more confused I got. DSC_0242.JPG.366b155e0571453108b91c03728c97d9.jfif
  4. Hi Mathy, Thank you for the response. Thank all others for suggestions, the syscheck one is an interesting alternative (though still would prefer something with a case ) As mentioned previously, I did have a 130XE with a faulty graphics chip, I now regret selling it as should've just swapped the chip with one of my other ataris! I had 5 ataris back then (amongst a ton of other computers), now I'm down to two as over the last two years I have pretty much decimated my collection. Both my 65XE and 800XE have 8 chips RAM, and both have the space for extra chips and this indeed the way I'll do one of the Ataris (probably the 800XE). Problem is, original Atari MMU is near impossible to obtain nowadays and the GAL chip needs programmed which unforunately I no longer have the hardware to do that. Not sure if there's any place in UK or EU that ships pre-programmed GAL chips? I'm not shy to do a bit of soldering though looking at other options as well. Even if I order the syscheck for one atari I'll probably still have a go with soldering on the other. So the big question - is there anyplace I can get the GAL chip programmed up front?
  5. Hi all, Selling my Super LDW 2000 disk drive. It's in very poor visual condition as has been dropped during shipping by the courier - the metal casing is bent at the rear, also it's scratched all over. I had this drive for the past 20 years if not more. I had it shipped from Poland to UK (Scotland) together with some other stuff, that's when the damage occured. Originally planned on getting this back to full working condition, but during the quarantine I decided to reduce my collection for all the things I am not using. It's just the drive - no cables or power adapter. It was working years ago, I do not know if it's still working - All the insides look OK and the drive was working last time I was using it... which, admitedly, was about 10 years ago. I am not sure what happened to the original power supply, however last time I was using this with a home-made one. Because of the condition the drive is in, selling as is, parts or repairs. Open to offers, swaps also considered - particularly for 65XE/800XE RAM expansions this is the ebay listing for it, unfortunately it was won by a 0 feedback account created on the day, which means I'm not getting paid for it. Before I relist this on ebay, maybe someone wants it here. https://www.ebay.co.uk/itm/Atari-65-800-130-XE-XL-Disk-Drive-LDW-SUPER-2000-not-1050/174277412503 Can relist on ebay if asked (still need to wait 4-5 more days from now before ebay lets me relist). the LDW2000 is the European equivalent of the LDW CA2001 LDW CA2002 and basically an Indus GT clone - from what I read what works with Indus GT works with this. < THIS IS NOW SOLD >
  6. Hi All, I'm new to this forum (but not new to Atari) and it would appear I am late to the party. Had a number of Atari's over the past 30 years, and recently decided to downsize my collection and focus on getting most use of what I have. So I am currently left with a 65XE and a 800XE, have the SIO2SD drive/tape emulator, and also some other peripherals (1050, 1010, XC12 etc). I also had a 130XE but sold it as it had a faulty video chip (display was b&w only). So looking for RAM extension, and was pretty much set at buying everything in order to solder the chips on the mainboard and expand to 320kb. Then i took one last plunge into the internets and here I am - an old thread with RAM cards ready made that are not that much more expensive than doing it myself. So my question is as follows - how do I get my hands on one? I understand the OP is no longer responding. Is anyone selling theirs? Is anyone making anything that would fit a 65xe/800xe (both of mine have ECI ports)? Or failing this, does anyone sell ready kits for onboard upgrades? If not, is there any place I could get all the chips, capacitors, resistors etc. instead of buying everything separately off ebay? Apologies for so many questions from the start, hoping someone is still out there willing to answer.
