I have made it once, but it's way back. It worked fine though; I have hooked an A500 with an A1200, an A500 with an A600, and no problems there.
If I recall correctly the only thing I did was to connect wires 10 and 13, but I'm not sure. The only thing I'm sure of is that it only took me 5 min. You can probably find a guide that takes you through the whole creation of the cable on Aminet. Send me an mail if I should dig out my old papers.
And then a little comment. I have been told that the cable mustn't exceed 5 metres. If it does files isn't transfered correcly, and therefore it gives corrupted files. I don't know if the info is correct, so if anyone can verify that I would be grateful. My cable is 5 metres though and no problems there.
