"The MX-20 had an Perkin Elmer panel sensor with parallel output to an SCSI PC interface board. It can do medium sized boards, up to 10" x 12"...The P-E sensor that came with my MX-20 was not it's original sensor. My MX-20 was non-digital, just a film based one (or phosphor plate based). The P-E had a low voltage differential, parallel, output that was sent through a cable to a PCI frame capture board. The board (made by Perkin Elmer) looked like a SCSI interface to the PC. The sensors are available on eBay, sometimes for a good price, but I've not seen a complete system, sensor, power supply, cables, interface card, and software, in a long time. A sensor is on eBay now, see"
