Still, doesn't solve the pinout problem

HaQue,
It does solve pinout problem, and in many cases is only way.
Of course having xray shot is ~30% of job, another 30% is track map analysis, 30% is testing, 10% is luck.
It still isn't fast method neither ideal (nothing is ideal), but the more statistics you gather the easier and faster analysis is.
I hope everyone understand here we're not talking about purchasing xray machine (If you can afford it, better to buy a small hotel, it's better business)
Usually, you can find 1-3 places with good xray service in big city - in technoparks, factory.
Forget about dental xray, it has 10-100 times lower resolution and high noise level.
