>this pin only goes to the user port and nothing else should make contact to it.
But it does.
It doesn't look like it's shorted with D1 but it is, which explains why this shit didn't worked. If the AR wouldn't set the data pins as output for whatever reason then I wouldn't noticed that and would became very confused in the future why my userport device crashes the CPU.

Now I feel like an idiot.

And the worst of all is that there aren't protection diodes on IEC data and clock lines but the official schematic claims that CR100-CR103 should be there.
I was wondering why the C64 crashed when I unplugged the serial cable.

I often forget that I'm the only one who likes messy wires but at least I used the same type of wire unlike some other projects I did where I used like 5 different types of wires. Also the whole mess does fits into the original case.
