Upgrading

In the last few months I've done a lot of OS upgrading. Something I like about older Macintoshes is that it is easy to get different operating systems because many of the older Mac OS's are free.

On Aurora I've upgraded (and downgraded) to these operating systems.
7.0._ > 7.5.3
7.5.3 > 7.5.5 (It corrupted the OS or something so I tried out OS 6)
_._._ > 6.0.5
6.0.5 > 6.0.8
6.0.8 > 7.0.1
7.0.1 > 7.5.3
7.5.3 > 7.5.5

And on Elixer:
9.0.4 > 9.1._
