Old Flash Unit with istDS

I have a Vivitar 283 flash unit (about 10 years old) that worked fine with my K1000 and ZX5n. Can I use this with my DS? It will fit the hotshoe but it doesn't have the same connections - not a TTL flash.

Yes, use it as you would on the K1000:
Camera in manual, set the shutterspeed to or below the fash sync speed, set the aperture as per what the flash requires (depends on the ISO set on the camera).
Some flashes has a table or display which shows or calculates the proper aperture.

You might want to check the flash trigger voltage before you try out the flash - this is well explained by JensR's who posts over at dpreview. His site: Your flash is probably fine, but why risk an expensive camera when it's so easy to check trigger voltage?

My 283 had about 500volts on the hot shoe connection. I only use it with a Wein safe sync.

I'll get the mult-meter out today and check the flash. Thanks to all who responded.
