Vintage Tandy Radio Shack TRS-80 Color Computer Game "Castle of Tharoggad" (sequel to Dungeons of Daggorath!). Requires a Coco 3 with 128k ram. Will not run on a Coco 1 or Coco 2. Also, requires either a joystick or mouse for control.Tested this year on my Coco 3, it is in working order. This cartridge is used and may show wear, please examine photos carefully. Specifically I have noted label wear (see photos), a few small dabs of white paint on the cartridge end, and some rub wear on the plastics. Will guarantee against DOA. Cartridge only (no box, manual, etc). I have other Coco Games in my other listings, will combine on shipping if you purchase more than one.
