The DCS200 weighs in at only 4 lbs with all of the batteries and internal disk drive. The 6 AA 1.6 amp-hr batteries that I put in the digital back (N8008s uses 4 AA Alkaline) were enough to fire off 50 shots to the hard drive and play them back on the computer. The first Digital IR "Sensor" that I worked on in 1981 took a 28-track tape drive, four racks of equipment, and all the power a P3 could generate to keep it running. The Air Crew could not turn the coffee pot on while we were running it.
So the Kodak was a real break-through. Its 1.6MPixel array was also state of the art for 1992, Kodak had a real lead in the field.
