Dave, you are right about the disks, there are some that really dont work this way but I found the 3M disks to work fine. I have some experience from 30 years ago :-)
My wife found some 720 k disks in her collection, she was laughing after I said I needed them.
her computer experience goes back to the 70's haha.

The battery is really damaged, I tried to charge it with an external charger but the Ri seems to be very high, I expect it to be one that has been on the shelf too long.
