On page 4, there is an "IDE Power" connector. It looks a lot like a 4 pin CPU fan connector, but it (obviously) provides different voltages that are appropriate for 3.5" IDE drives (5V, 12V) and the ...

Parallel ATA (IDE) uses 40 pins, not 26. 26 was for floppies. But it's a standard 40-pin "header" connector. Sometimes called "IDC". CF cards have the PATA interface on a 50-pin connector. I don't ...

We all like to standardise. But there doesn’t appear to be any pin number system defined for one of the most popular wire-to-board connector sets. Marking the PCB pin header isn’t so important, as the ...
