@ Jim:
If you use 3.5" HD disks on the Amiga, to copy Amiga DOS disks then you need to cover the right-hand hole with some opaque tape (not the write-protect hole) and just format it in the usual way. Of course you will then not have a 1.44mb disk, you'll have an 880kb disk.
Quitting from games: most disk-based games have no quit - you must reset or turn off.
Keyboard: he he that brings back memories. One day I spilled a whole glass of sticky mango juice on my B2000 keyboard and I had to take it apart and bath the plastic pieces. The keys I had to clean with those little alcohol swabs they use in hospitals before you get an injection. Not a nice job.
