Its all very clever. Till it doesn't work. A long time ago, we got EA's "seven cities of gold" from my parents for apple.

My brothers and I were all excited but it would start to load then the drive would make a strange sound and it didn't work. We exchanged at the local software store, the next one did the same thing.. We tried on a friends apple //c and it worked there. Our //e drives must have been slightly out of spec. It was bitter disappointment. But a valuable lesson.

I had the same experience with some of the games I bought. I ended up having to get a pirate copy and overwrite the original tape or later disk.
