you want <COMMAND>-E for copying. the "1" thing (<COMMAND> <SHIFT> 1 if 
I remember right) was the "force eject" for the first floppy drive at 
startup if normal methods (drag-to-trash or eject command) failed.

You want to use either a Mac II or earlier, or a SE/30 or IIcx/IIci 
with an external 400 or 800k floppy. The SuperDrive (original 
SuperDrive, not the "new" CD/DVD one) [present on all Macs since the 
IIx, many IIs and some SEs (SE FDHD)] has the smaller head size and 
your older machine won't read it properly. WRT the swapping- can't 
recall at this point if changing the disk cache/RAM cache (depending on 
your system version)  setting makes any difference, but the default 
gives you lots of wrist exercise even on a 4MB Mac SE/800k.
