Offered here is RARE Commodore 64/128 AZTEC CHALLENGE software issued by CPOSMI Corp Software in 1983 for use with the Commodore 64 and 128 computers. Software was tested and loaded properly as shown. This is used so there is wear but overall in excellent condition. Although it loaded for me, it is sold \"as is\" as there are too many factors to prevent it from loading on your system; ie worn datasette belt, dirty datasette heads, RAM issues with your 64, etc. I ship worldwide. Please check out my other listings. Buyer pays shipping. Good Luck!
