Sun Diagnostic Computer help needed

If this were mine the first thing I'd try to do is to interface a "less proprietary" computer if possible and figure out how to work around floppy disks, IE USB stick, even a hard drive. It may NOT be. I have an old HP optical spectrum analyzer which requires a floppy to operate. Unfortunately I don't have that disk nor have I found a way to get one.

Another sad story is I have a complete set of old Autocad software on CD........but you need a floppy to install it......they were VERY anal about their overpriced software!!
