Re: Slide projector help needed
that's called a "DIN-Stecker 6 polig" in german if you should browse E-Bay sites.Keep in mind, besides your standard size plug/socket there's also a "Mini -DIN-Stecker" (Stecker=plug)
It doesn't look like a 60 ies model to me though.
Theses DINs were in use till the 1990ies afterwards there came the cinch plugs.
What you have was made mainly for audio uses and also for TV sets before the recent SCART sockets were introduced.
So your projector was built before 1990 and I hope after 1983, when the new slide magazines were introduced.
I would strongly recommend you to get a new control for it, since I doubt there have been better projectors available ever. You got a real gem there.
If you don't get the original thing by LEITZ you should try to find somebody who is a making one for you, that means who can change the plug for you, which is very easy to do, with only 6 cables.
Oh and It would be vital to know the exact model, since there were several different Pradovits.
I googled P.Color and found an old user's manual in german:http://www.l-camera-forum.com/leica-wik ... -Color.pdf
Is this your projector? If so, it was built from 1974 onwards and the thing you're looking for is called "Fernbedienung" (remote control). It looks quite different, from what Kev has found.
It's for adjusting the focus as well as advancing the slides.
