Preserving old literature

If we are talking about the same device... The Datacopy 300 doesn't provide _any_ internal storage for images. It's just the camera. It contains a linear CCD image sensor that's mechanically tracked across the frame. There's electronics in the camera to control the movement of the sensor, to digitise (and correct) the pixel intensity values, etc. Mine has a Nikon lens mount on th front, but that, I suspect is internchangeable so other mounts might have been used. On the back is a DB25 connector. This is _NOT_ RS232. It's not anything standard. It's a custom interface carrying power, control lines and data lines. I have a PERQ 2 I/O option card which I believe is the interface for this camera. Sorting out what it does and how to drive it is a project I must have a go at sometime... If you don't know what it can do, or where to find one (I assume they are not common), then why on earth are you considering it? I can understand somebody wanting recomendations on a currently-produced device. I can understand people wanting information on some piece of classic hardware they've just found. I can also understnad people who want recomendations on what classic hardware to look for (as so much modern stuff is so poorly made). But to pick on a particular classic model for no reason seems a little strange. -tony
