The Omni Group has been around so long — 25 years! — that floppy disks are a memory rather than a thing we just heard about once. Across from Ken’s office we have a NeXTstation which still uses floppy disks. (It takes 2.88MB floppies rather than 1.44MB floppies, because Steve wanted only the best in his hardware.)
Here’s a detail from the T-shirt. Five disks, five cool colors.
