ISO 9660 wasn’t around until '88, and even then, its read-only capability paired with high costs wouldn’t make it viable until maybe a decade later … ironically, around the time the system was deployed.
I know I was still using 5¼" floppies at least a bit into the early '90s, though it’s been long enough that exact years elude me.
I was also still developing technology that used 3½" diskettes well into the first decade of the new millennium - though I finally managed to migrate newer systems to CD-R around the end of that decade.
