This past spring my son (a HS junior) took a course in photography,
and was given an assignment to shoot several rolls of 35 mm Tri-X
and do the lab work at school. The school had several old SLR's,
and he complained to me that he couldn't get one at the last
minute, so I dragged out my old Minolta SRT-101 and Vivitar 283. I
know it had been a good ten years since that Vivitar had fired up.
The alkaline batteries were leaky, but there was no damage.
I was amazed to see you can still buy a 283.
Put new batteries in, cleaned the contacts, and it worked
perfectly. I've been thinking I might get a bracket & and try it
with my C-2100.
I would be extrememly careful in doing this. According to the web
page on flash voltages:

Older Vivitar 283's could send 600 volts through the flash contact,
and Oly says the maximum for the UZI is something like 6 volts.
This didn't affect the older manual focus cameras, but can be
deadly for the newer autofocus 35mm cameras and the digitals. If
you suspect your flash of having too high of voltage, you should be
able to protect yourself with:
