I have a Delfina Flipper card I want to use via the Deneb clockport. But I need to know which Deneb clockport pin is pin 1 to correctly orient and plug in the Delfina cable.

The Deneb docs don't mention clockport pin 1.

You will need to locate pin 20 that has +5 V on it. (multimeter)

Rather non-user friendly, but that's way I tested and got it working.

They start counting from pin 19 not sure why, probably some other versions exist

The original "clock port" header on the A1200 motherboard was a 40-pin affair. The first 18 pins were for 1MB of Chip RAM, the remaining ones were for adding a clock. When they finally shipped the model, they decided to include the 2nd MB of ChipRAM on the board, so the first 18 pins are useless.
