Classic mac fun (and some questions)

My goal here is first to get the quadra on the network so I can share files with it. Also, I'd like to be able to read CDs or DVDs from the quadra. Once one of those is successful, I plan to use ADT to transfer a prodos or apple 3.3 dos disk image to an apple 2gs over a serial cable, then create a bootable floppy for my 2e. :-P lol. It's looking like a fun project. I should note that I have zero floppy disks for the mac or apple 2e/2gs. So this is sort of a fun boot-strapping project to see if I can get there from here. Much to my surprise, the quadra 700 detected the two scsi hard drives and dvd drive. The quadra already had some scsi utilities and each of the drives show up. One of them has a mount button, but it refuses to mount a CD in the DVD drive. No surprise there I guess. Any idea how I can get the machine to mount a CD or DVD? I might have a termination problem. I have this black centronics thingy with the apple logo on it. It sort of looks like a terminator, but you can plug another centronics cable into the back of it, so I'm doubting it's a terminator.

Networking doesn't seem to work. I get a light on the hub, but it doesn't seem interested in letting me get to the network.

I suspect the floppy drive is bad. I put a new HD floppy in the drive. It detects it as a 1.4meg floppy disk, but formatting doesn't work. It claims the disk is bad. I have another drive in the IIfx that I might try swapping in to see if I can get the floppy drive working. I copied a dos file to the floppy as a test to see if I could get the mac to read it. No luck. It wants to format the disk. Any ideas on how I can be able to share floppies between the PC and mac? I know the mac drives are a little odd.
