The amiga video port out is rgb.
The cable you have is a rgb 23 pin to (guess) 9 pin for the 1080.
You also have a 23 pin to 15 pin adaptor (which I gave you)
In order to connect a rtg (read vga) video card, you will need a 15 pin vga to 15 pin.
The pass thru from the picasso2 is also 15 pin vga (other cards ie spectrum are 9 pin)
With the TIMM which has a 15 vga in, the min is a 15 pin vga to 15 pin.
option 1: By using the 23 to 15 pin adaptor with the vga cable to the TIMM.
OPtion 2: using the 23 pin to 15 adaptor with a short 15 pin to 15 pin vga cable to the pass thru and then a longer 15 pin vga to the TIMM,
You have a complete or both the the 31khz and 15khz signals going to the TIMM.
You still RTG software.

Thanks for clarifying that the PicassoII card has a 15pin input port and not the 9pin input port that the Spectrum has. I have both video cards and could not remember which one of them had the 9pin input passthrough port. That makes it easier for AmigaSociety to get the cables he needs to utilize a one monitor solution with the TIMM and the PicassoII card on his A4000T. He might just need a gender changer, depending on if the port is male or female.
I will take a closer look at it tomorrow when I deliver it to him.
