XO-1.5's sudden death - oven resurrected!

[kgordon420 at gmail.com]

I've given multiple machines to anna to 'bake'.  Alas, it is my feedback that In general, they've ressurrected but only for a short period of time.  I am unaware of a long term solution for the ramp machines.

Yes, every XO model meets RoHS.   Starting with the latter half of XO-1.5
production, we also meet the USA's Consumer Product Safety Improvement Act
as a child's toy.  This covers nasties like phthalates (the power supply cord
wasn't passing at first).   The motherboards are not, however, halogen free.

Despite all this certification, I know that compliance checking of suppliers/materials
is expensive and rarely done periodically (the power supply cord manufacturer
assured us that the second and third failing samples were phthalate-free!)
Take caution (and preheat the board at 80C for an hour, not 15 min.)
