I suspect the down votes are coming from folks not understanding what the camera is.
The FD7 was released in 1997 and records 30 images to a 2.5" floppy disk. Yes, really. Later Sony cameras had built in mini disk CD-R drives. At the typical 1.4 MB disk size you could fit 40 standard sized JPEGs. These images were captured using a 640x480 sensor that sensor was originally intended for television cameras. In order to hit 640x480 it needed to capture and interlace two different frames.
Early digital camera days were very inventive. Thankfully people bought them. If they hadn't we probably wouldn't have made it to where we are as quickly as we did, if at all.
