Vintage Tandy Radio Shack TRS-80 Color Computer Game "Dino Wars".  The cartridge is authentic, produced by Tandy/Radio Shack back in the 1980's.  Requires a Coco 1, Coco 2, or Coco 3 with 4k or higher ram (16k or higher recommended).  Tested this year on my Coco 2, it is in working order.  This cartridge is used and may show wear, please examine photos carefully to satisfy yourself with condition.  Actual cartridge you will receive is shown in photos.  Typical wear for Coco carts in general includes: label spotting (caused by the glue Tandy used during manufacture), label edge wear (tears &/or creases), label lifting, and rub wear/scuffs on the plastic game casing from use.  You are purchasing the cartridge only (no manual, box, etc. included).  I have other Coco Games & Programs in my other listings, will combine on shipping if you purchase more than one.
