Vintage Tandy Radio Shack TRS-80 Color Computer Game "Shanghai" (Mahjong Tile Game). Requires a Coco 3 with 128k or higher ram.Will not run on a Coco 1 or Coco 2. Tested this year on my Coco 3, it is in working order. This cartridge is used and may show wear, please examine photos carefully. I have specifically noted some label wear (some spotting / discoloration from label glue, ripples, wear around edges, etc) as well some typical light scuffs from use on the plastics. Will guarantee against DOA. Cartridge only (no manual, box, etc). I have other Coco Games in my other listings, will combine on shipping if you purchase more than one.
