What is it you're trying to get onto a floppy? Something for a non-HD Mac? Or is this just a way to get something onto another Mac, both having hard drives?
Can you expand the disk image on the Pismo hard drive or at least copy the files from the image to the Pismo HD? And initiialize a floppy? Just extract the files to a folder and do a drag and drop to the floppy. If it crashes on eject, can you shut down the Pismo with the floppy still mounted? Then hold down the mouse or button on restart and that ejects the floppy before it's mounted again.
But reading a PC disk directly might be the simplest. You can always add a null-modem cable and send it the way we usta had to with porting between different systems. No floppy needed.
Me being an AOL member still paying for (but not using) their dialup service, I can run an ancient os7 version of AOL and check my email and accept a download (at dialup modem speeds, of course) directly to most any old Mac I own newer than the Mac Plus. Ok, probably not an option, but one I've used for small files. (Try finding an old AOL free floppy, for one thing, lol!)
When I had a bunch of stuff to move, I had several SCSI drives I'd move around as needed, some of them even had a PS and even an enclosure! Or I used an external SCSI CD drive. Then there's AppleTalk, again very slothlike, but it worked with only a cable and some sharing settings. Appletalk might be more of a challenge on a Pismo though, no ADB serial port for one thing.
Just some random thoughts, since I've used all of those over the years when the floppy method failed due to a bad drive or for whatever reason.
