  1. Hello all, I bought a 1050 drive from a nearby vendor that knew nothing about the drive. When I took it apart to service it, the shielding was still in place, so I assumed it was a stock drive. Because my original 1050 had an ICD chip i wanted to find a way to bump this drive up to true double density and high speed I/O so I eventually bought a Happy board from Atarimax. A couple nights ago, I opened the unit to install the Happy board, and following the instructions, I removed the shielding, and that's when I saw the double-height chip with the letters "ICD" on top. So, now the question is, should I go ahead and install the Happy board and remove the ICD Doubler, or just leave the Doubler in place and move on? I suppose I could buy another 1050 unit and install the Happy board in that... I'm not really concerned about the other features of the Happy board, I'm not going to be duplicating copy protected disks, so I'd probably just use it in ICD emulation. Are there any reasons to use the Happy 1050 over the Doubler?
  2. Good morning, AtariAge'rs! Has anyone ever found or developed a replacement adapter that will allow ICD's MIO to be connected to the 130XE? If so, could you point me to where I can purchase one? Thank you, in advance! --Timothy Kline
  3. Here's one that looks quite interesting... http://www.ebay.com/itm/Atari-R-Time-8-Cartridge-For-Atari-Computers-Never-Opened-/131053324642?pt=LH_DefaultDomain_0&hash=item1e83630962
  4. Is anyone familiar with the author of this blog, Igor Gramblička aka Igi? It's a really good multipart writeup with a lot of consolidated detail about the US Doubler mod. (in slovak, but google translates OK) I noticed his example pictures of homebrew US Doubler 6810 ram stacks came from a post of mine here on AA http://atariage.com/forums/topic/220482-1050-us-doubler-speed/?p=4011333and MEtalGuy66 http://atariage.com/forums/topic/220482-1050-us-doubler-speed/?p=3664839 Link to part 1: Slovak: http://blog.3b2.sk/igi/post/Atari-1050-ICD-US-Doubler.aspx English Google Translate: https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fblog.3b2.sk%2Figi%2Fpost%2FAtari-1050-ICD-US-doubler-Part-2.aspx&edit-text= What I was really impressed with, is the PCB featured in "Part 2" and "Part 3" that not only looks nicer, but addresses his concern of lack of heat dissipation by stacking them vertically. I wonder if these PCB's are still available. The author says they are by Radim Poláška, but I'm not sure how to contact him. Lastly, he described variations of the firmware in Part 4. Interestingly, what he named as "Version 1" firmware is what I previously suspected somebody patched from the original ICD ROM for a faster stepping rate, and his "Version 2" being the original code and stepping rate found in stock US Doubler upgrades. This was previously discovered / discussed in this thread: http://atariage.com/forums/topic/275166-one-last-eprom/?p=3991800
