BTW it works with my custom hardware running a modified version of 7c81 bitfile that communicates via EPP.

Thank you all.
So, I will give it a try. As far as I can see there is no header on the motherboard (small form factor).

The card arrived. PCI to parport Sunix. Looks like it works.
But I try to power the 7i43 and it looks like it is faulty. With W4 and W5 down I can make the 3 leds on the bottom light a little bit at 2,9V and 0,5A. But at 5V and around 0,4A nothing shines anymore. Looks like somithing is wrong.

If you don't get a power LED at 5V, that's not a good sign
as it may indicate a 3.3V power issue (bad chip?)

I dont know. I bought it used.
U6 aprox. 1,23V
U10 aprox. 0,60V
Supply each 4,87V
3,3 V header also 0,6V.
So yes. Looks like a short in any chip.

Ok. To me it looks like that the voltage regulators are fried. Maybe an overvoltage damage.

Could also be an almost dead short on the 3.3V rail.
If you have a lab supply you could set it to 3.3V,connect
it to the 3.3V rail and ramp up the current to see what
part(s) get(s)s hot.
Where are you located?
