Hi all,
my single 60GHs is dead and i want to revive it (if possible).
Why? No offense, but selling the four fans will probably net you more than the thing will ever mine again.
If you just want to fix it as a challenge, the 60GH/s single is extremely similar to the Jalapeno board that BFL released the schematics for. You can try flashing the unit with the latest firmware from an SC if you want to try that.
