This medical training disc appears to have been intended for use with some sort of touch-screen system also involving videocassettes. There are on-screen prompts which mention playing/recording/rewinding of videocassettes. Produced in conjunction with Merck & Co. Inc. Features biliary & pancreatic system "case work-ups" on five "patients". Each includes history & physical exam, lab data, x-rays, diagnostic and therapeutic endoscopy, and histology. There is one chapter encoded, numbered 0. Nothing resembling a reference number appears anywhere on the jacket or disc labels. The "dead" side is a solid white non-reflective surface.
