Petri computor 35

[DanP]

Hi, I have just joined this forum as I have a couple of the Petri 35 computor cameras. One works fine and the other has a shutter problem. Does anyone have access to a copy of the circuit diagram or service manual for this camera? I think the problem is the electronics as the shutter only works at default 1/30th sec.
Thanks.

That's a camera that doesn't get discussed often in this forum. There were three versions, I think the second one had improved electronics and shutter and is more sought after - which one do you have? There is speculation that Yashica made the electronics for them.

It would be interested to see if anyone has any experience with these cameras.

I think there maybe be 4 versions? I have the 2nd version, i think?. It has the battery check button and has the the f2.8 lens. I think version 1 was without battery check button, as I have seen one of these, and version 3 the 35 computor ii has a f1.7 lens? The computor iii uses a seiko shutter.

I have a Yashica electro 35 that uses Copal electronic shutter and the system looks very similar to the Petri I have but all a bit smaller.

If I can get a schematic for the computor I, I maybe able to fix mine?
