Quoted from billsfanmd:
crap that sucks...what do you do now? Is helmut selling any?
Didn't think about asking Helmut since HP is dead and shuttered. Assumed his HP address would have been disconnected as standard protocol. Trying to get the boards repaired. A failed chip on each was initially replaced, but another culprit must still be tracked down. Would have swapped in spare i/o boards right away if I had access to buy them or alternate replacement boards.
