Hey there.

So, fist steps are done to bring my PDP-11/34A back to life.
The PSUs had to be redone and slowly awaken from their sleep.
After that, which takes about a week, done by my friend Gnther Honisch, i put back those parts together and first time after about 30 years the PSUs got powered on again.

No magic smoke escaped and after checking the voltages +5V, -15V and +15V where OK on the UNIBUS. So first step ok.

After this step i put in the Terminator Card M9302, some NPG Cards and the KY11-LB Console Card. First it worked fine, the Console was online i cold type in some numbers. But after a few minutes the Console got stuck and no longer showed anything. :-(

So, next step, get the console working again.
Stay tuned!

Regards
Andreas
