As you may or not know I have a powermac 7100/66. I bought system 7.01 on ebay today for $11 shipped and I want to know if it will work on my system. I heard that only systems after 7.2 (or around there) work with powermacs. Is that true? Can I still install it? P.S. was $11 a good price for an original set of system 7 floppies?
