Vintage Tandy Radio Shack TRS-80 Shanghai Program ROM Cartridge (Loose - Tested & Working)

First adapted for home computer systems in the late 1980s by Activision and distributed by Radio Shack for the Tandy TRS-80 Color Computer, Shanghai is the definitive digital adaptation of the ancient mahjong solitaire tile-matching game. Challenging players to clear a pyramid stack of 144 intricately detailed tiles by matching open pairs, Shanghai became an instant classic in puzzle gaming due to its deep strategic layer, calm pacing, and high replay value.

This listing features the original Radio Shack TRS-80 Shanghai Program Pak cartridge in loose, pre-owned condition. The cartridge has been bench-tested and confirmed to be 100% operational, booting smoothly and loading instantly upon insertion into the TRS-80 cartridge port. The gray molded plastic casing and front graphic label display age-appropriate vintage surface wear, making this a great addition for retro computer collectors, puzzle game fans, and Tandy TRS-80 software enthusiasts.
