Re: the questions about making floppies, Disk Copy 4.2 will run on a Plus with System 6 and is capable of imaging and restoring 400k disks. It's what I used to make floppies for my 512k. (I even have a Localtalk->Ethernet bridge set up so I can drop downloaded disk images into a file share on a linux server and directly image them from there. One of these days I'd like to find a 9 pin phonenet adapter so I can try putting the 512k directly on the network and skip the Plus intermediary, though.)
