Film Recorders (Agfa PCR II)

Yes. I got thtis thing along with soem I2S image processor/display units (high-end (for 1979 [1]) graphics systems for PDP11s and other minincomputers. It was possibly used for pritnign the output of one of thsoe. [1] IIRC the resolution is 512*512 pixels. The units have multiple 'byteplanes' of that size, the outputs of which go through programamble look-up tables, and are then added. further lookup tables the go between the outptu fo the adder and the DACs (8 or 10 bit per colour). There are lots of other feautres too, like an overlayed bitplane for text, historgramming of the displayed data and even somethign called the 'feedback ALU' where planes 0 and 1 becoem a 16 bit accumulator, you cna then dio the function Acc := Acc Op Another_plane. Where 'Op' is anything a 74181 can do, and the othee plane cn be arbritratily shifted around. Oh yes, and unlike the GPU in the Rpi, you get docs. Real docs. There's a _large_ binder of scheamtics... Yes. This is actually a fairly simple bit of metalwork. From what I rememebr it's basically 2 flat plaets at right angles. One is fitted to the front of the Videoprinte, the other sticks out at the bottom like a shelf to suport the caemra. There are a couple of little side plates to strengthen it and keep it rigid. It's all bolted together with allen cap-head screws. The 2 thumbscrees that fix it to the videopritner look to have been home-maed on a lathe. The knurling pattern is differnet to the official ones, for example. In the horzontal part of the bearcket there's a slot, I suspect a 1/4" BSW screw went through there and inot the tripod bush of the camera. I thinmk it took a noiraml SLR camera (I sould guess a Nikon or a Cannon, but I am not sure). I susepct it used a lens and extension tubes from that system, so the back of the lens to the film was easy to keep light-tight. There woas probably some kind of tebe fro mthe frojnt of the lens to the vertal part of the bracket, it might be soekthign as simple as a lens hood. The bracket is failrly deep from the lense hole ot the horizotnal part, I suspect it took a camera wit ha motordrive and that the mystery connector connected to the remote release of that. [Hacking an SLR onto this] I have plenty of cameras that I need to repair, but none of them are electronic (by choice!). But unless you want soemthign exotic, broken 35mm electornci cameras are not that expensive now. You might even get a working one with an electronic remote release for not too much money. As for the lens, an elnerger lens would be a good choice I think. You would have to get ot make an adapter to fit it to the caemra, and get soem kind of extension tubes, buc such things do exist, or can be made. -tony
