An anonymous reader shares a VentureBeat report:The cathode-ray-tube technology that powered the monitors for nearly every classic arcade game in the twentieth century is defunct. Sony, Samsung, and others have left it behind for skinnier and more lucrative LCDs and plasmas, and the CRTs that are left are about to sell out. The current stock of new 29-inch CRT monitors is dwindling. Online arcade cabinet and parts supplier Dream Arcades has fewer than 30 of those large displays sitting on its shelves. When it sells out of the current inventory, it will never get another shipment in that size again. "We've secured enough [of the other sizes] to get us all the way through next year," says Michael Ware, founder of Dream Arcades. "After that, that's it." The future of arcade-cabinet restoration is looking bleak. "The old arcade games are like aging people," says Walter Day, founder of high-score-keeping site Twin Galaxies. "They have old livers and aging kidneys. There will come a day when very few arcade cabinets have original components. Time will wear them out." To be clear, it's not that games like Donkey Kong or Pac-Man will suddenly become unplayable. The games can run on newer LCD screens, but they may not look as the developers intended.
