Well I just powered it on, but I'll have to decipher the diagnostic light codes in the back, and also dig out my good-known-working cable and monitor, to make sure it is not a fault with either of those. I do have two good working dec 350's. I also have a Russian Elektronica-85, which is an identical clone of the dec 350. It unfortunatly DOES have a bad PSU. As I am rusty on my cyrillic alphabet, and having no working documentation on the power supply, it will be slow going. Although the Electronica is "supposed" to be identical to the Pro 350, The wiring connector(s) are really alien, leaving me to suspect that the wiring might not be identical to decs. The worse thing I could do is muck around with and blow-out something I could never hope to replace. It really is an interesting machine, almost identical to the Pro350 in dimensions and look, even the way it opens up and is arranged.It does have some differences though (like the cpu) and I think the CTI bus cage is not electrically identical. I will play with the Dec350 tomorrow or later this week, and if it proves to be something I can't fixed I'll move the DECNA card over to my other Pro350. I believe I might even have the ethernet software (POS) for the card around here somewhere. They are as rare as hen's teeth, and I would have paid handsomely to get one if I could ever even find one, and this one fell into my lap..real cheap too!!
