+Stephen Posted February 12, 2018 Share Posted February 12, 2018 Hi all, Our AA friend @Stephen has kindly offered to repair the board. I hope that we all hear something positive from him now that the board is in better hands! The workbench is having a special place cleared for you right now. I'm in the midst of a bad NE winter, so equipment in my garage is harder to access. But I'll be posting 1st progress update here in a day or two. 2 Quote Link to comment Share on other sites More sharing options...
atari65xenajm Posted April 22, 2018 Author Share Posted April 22, 2018 This 65XE is up for auction. Stephen has helped a lot, but this device has problems far more than anticipated. https://www.ebay.com/itm/253577081644 Quote Link to comment Share on other sites More sharing options...

Stephen has helped a lot, but this device has problems far more than anticipated. https://www.ebay.com/itm/253577081644 Guys, if anyone is interested in this board, I did the following repair work to it: See photos here Repaired 3 broken traces / pads: from CPU19 (goes to a pad below ANTIC22) from CPU10 (goes to a pad above ANTIC9) from CPU22 (goes to a pad next to U5) Verified continuity at the sockets for the following pins: ANTIC22 to CPU20 ANTIC23 to CPU18 ANTIC24 to CPU17 ANTIC25 to CPU16 ANTIC26 to CPU15 ANTIC27 to CPU14 ANTIC28 to CPU13 ANTIC10 to CPU12 ANTIC11 to CPU11 Socketed the PCB with machine pin sockets for: CPU 40 pin double wipe GTIA 40 pin double wipe ANTIC 40 pin double wipe BASIC 24 pin double wipe OS 28 pin double wipe FREDDIE 40 pin machine POKEY 40 pin machine PIA 40 pin machine MMU 20 pin machine RAM 16 pin machine Put in new RAM, machine booted straight up to BASIC! Bad news - carts do not work (they are simply not read) but I am at a loss. I verified continuity between the bottom of the 65XEN's motherboard and all pins of a plugged in cart+ECI device so I don't believe this to be a mechanical issue. I have tried two different MMUs and two PIAs. I hooked keyboard up to the machine to test it further. Initially self test passed. But then it started failing, and now the machine is not booting again. So I am at a loss here - I have verified the MMU, Freddie, CPU, ANTIC, GTIA, and RAM work in another machine. BTW - here's two videos showing some work on the machine, I did them as mini-tutorials for de-soldering. 2 Quote Link to comment Share on other sites More sharing options...
+Stephen Posted May 2, 2018 Share Posted May 2, 2018 Just wondering if anyone here bought this? Would like to know if (when) this eventually gets fixed what the underlying issue was. Quote Link to comment Share on other sites More sharing options...

No one Stephen. It is still on eBay. https://www.ebay.com/itm/253591972140 Quote Link to comment Share on other sites More sharing options...
