Hello,
I wanted to know if my BPPC behaves as a normal or hides some problems. Every time I power on my Amiga with the BPPC I keep on waiting for minutes and the screen stays always black. So I am forced to do a reset.
Only after this reset the system starts operating.
Is everything normal ?

Yes, this is normal behaviour for some BPPC models. Usually (but not neccessarily) this occurs with the ones that have a 68040 - but that's just a rule of thumb.
The system just crashes at power-on, because it was never meant to cold start something as huge and power hungry as the BPPC.
Sometimes feeding power to the floppy power connector on the A1200 motherboard fixes it, sometimes feeding power directly to the BPPC fixes it - but often, it's not fixable.

I used to have that problem with one of my amigas and I checked both 2xblizzPPCs....
I should add also that if my amiga was "cold" (first boot of that day) I needed to let her in that black screen for some minutes before I reset, otherwise it still couldn't boot.
the problem solved when I modified the power supply (atx) to sent from seperate cables power directly to amiga's floppy connector and giving more cables from atx to normal power input of my amiga...
although I can't be sure only for power because I can't remember if that was the period that I changed my amigas motherboard with another one...
PPCs are the same although.. and the problem stopped.
