Yes, a normal, often electromagnetically-defelected

mount it along the axis of the camera. Others (particularly
semi-professional models) have a removeable viewfinder assembly. In
these, the CRT is mounted across the body of the camera, with a 45 degree
mirror ro reflect the image into the eyepiece. If you can find one of
these, you might be ablr to use the viewfinder module as-is. The
connections will typically be a power input (12V?) and composite video,
maybe with some extra signals for things like the record-on LED. The
service manual should document the conenctions...
There have been B&W and color. The B&W is, of course, capable of higher
resolution than the color. I was pleasantly surprised at being able to
read 80x25 CGA text on one.
