get a cheap Vivitar 283 and a PC to vivitar cable.
Now that would be awesome, I use my 550ex in manual mode anyway. I love that thing. I got a few diffusors for it.

I figured the Nikkormat flash cable only told it when to fire, cool beans I'll have to get up on this. Thanks.

Gonna look a bit weird my 550ex hooked up to my old Nikkormat, but it will work.
