  1. @santosp, Can confirm my interest in one Freezer. PM me with details, please.
  2. Oh! Almost ordered this 8-Bit Classics cable, based on your recommendation in another thread: The issue with Lotharek's cable must be thinner wires then? If someone could dismantle its plug to confirm, that would be nice
  3. This little floppy drive I purchased recently. You may notice the seller shot pictures with dirty stockings, so bidding on this item was like gambling. It has been delivered yesterday and well... I'm a happy owner so far The unit itself is very clean, no yellowing or scratches. Sold as "untested", and I have to fix the PSU first. The power cord was obviously replaced as it's grey, and the wall plug has been cut off. Then I have to dig my stuff for SIO-SIO cable. And a diskette, definitely I'm gonna need one.
  4. Tell me about it... I’m looking forward to get one of these Competition Pro-likes from China. The price is cheap, but they didn’t start shipping so far 🙁
  5. Almost. Antonia is Simius’s granddaughter 🙂
  6. In 130XE it’s „Harry Fat” for 130 and „Harry Obese” for the XE.
  7. Another batch of freezers, finally! Have been waiting for this since 2016 🙂 I’m definitely in for one.
  8. There is a member on Atari Forum, currently selling custom made badges for maxed Falcons. Notice the hardest part, that is embossed lettering with brushed finish, have been nicely re-created: http://www.ebay.com/itm/Metal-badge-for-Atari-Falcon-CT60-CT60e-CT63/164164208291 Maybe the guy even shared some details about technique used in process, unfortunately http://atari-forum.com is down atm But apparently, there is a way to make a small batch of exact replicas of any ST/XE badge.
  9. You can still buy a new case for 800, i.e. from B&C Computervisions: https://www.ebay.com/itm/Bare-Top-Case-for-Atari-800-New/132856341797 If you really want to fix yours, check out this guy's blog for tips. He is an artist 🙂 http://www.retrohax.net/extreme-refurbishing-episode-2-atari-800-xl-part-two
  10. Here is up-to-date link to Jerzy Sobola's website: http://www.jsobola.atari8.info/dereatari/index.html
  11. Well. The picture is sharp. Moving objects are fluid. The scrolling on Grand Prix Simulator looks very decent. It's excellent! Some standard questions: 1. Is it lag-free? 2. Any special requirements for VGA display? This device will work with any monitor, tv, projector with VGA input?
  12. @SainT, I'm in for one Multi Card. Please put me on the list. Thank you
  13. Each NTSC Atari I have seen before (not in the flesh actually, I mean pics ) was US origin. Therefore it has FCC ID# on bottom label. No FCC compliance text = the machine is probably PAL. Although I may be wrong, just guessing
  14. Some science here: http://citp.princeton.edu/research/memory/ Atari found out, that DRAMs from particular series "remember" bits for a long time after the power is off. And if you switch power off and on to force cold start, the computer boots with garbage on screen, then hangs up. So they developed a fix: mix each set of DRAMs with a single chip from another batch, the "fast forgetting" one, and the assembled computer passes tests OK! It was easy and cheap, so they did it. Can't see anything unbelievable in such a story. It is recommended to add one or two different chips when replacing defective RAM in XL/XE's, it's common practice actually. And I didn't make it up, it came from guys good at electronics.
  15. About this single different chip, think I know the explanation. It might be factory fix for some known bug. RAM chips are able to keep data stored up to 15sec. without refreshing. And there is no procedure for cleaning up/zeroing memory that Atari performs on booting. So - if you power off the computer, then turn it on immediately - it is likely that Atari just hangs up due to some residues of data still existing in RAM. A working solution is to replace single memory chip with another with different access time. For instance - one chip 200ns vs all the rest with 150ns. Or just put in one chip made by another manufacturer - the one replaced will be almost identical as the rest, but almost is enough to do the trick.
