Please let me know what are your findings since I'm also playing around with an old flash (with a trigger voltage of 230V) and I'm still looking for ways to trigger it using my 50D. I did try to check out what the 50D does at its output (PC terminal) but I'm still not sure and in order to check it out I believe one will need an electronic oscilloscope and I don't have an electronic one at home[]
