I understand that you have to be careful when using older flashguns with DSLR's due to trigger voltage but does this apply if firing it by PC cable as well as hot show.

Depends on the camera. Fujica state 400 volts max, Canon state 5 volts max.I've no idea about the PC cable but it's fairly easy to check the trigger voltage on the flashgun if you have a multimeter.
Hmmmm. There is a WIDE range in the voltages of the Viv 283. 110V to somewhere near 300V is possible. I'd check what it is first. Just go for a wireless trigger like a PW or somesuch. Alternatively go for one of the Voltage neutralising sapcer things that go between the Camera and the Flash (Wien's, Wein's?)
Yes...the flash is still connected to the hotshoe of the camera, albeit with a cable in between. The 283 Vivitar is something like 300 volts - modern flashguns are about 6 volts.....
A PC cord and an extension cable which slots in the flash shoe are two different things.
Thanks CT
so you're saying it's ok to trigger my 283 from the pc socket on the d200 even if I don't know the trigger voltage. I would have thought the pc socket and the hot shoe connection would be in parallel and therefore would both be sensitive to the trigger voltage. That is the crux of my original post.
Well that's always been my understanding Peter. The hot shoe apart from firing the flash, communicates lots of other information from the camera to the flash with modern kit, hence the 5 connections on modern camera flash shoes. The PC socket just provides a simple trigger for the flashgun.
Wait and see if anyone disagrees with that if you want to be on the safe side.

Fujica must have a thyristor in the body.
