@Onj Yes I don't think the LS drive got any bigger. Backward compatible with floppy disks though. I had a jazz drive connected to an Emax keyboard for a bit. They were bigger weren't they? I think the Emax had something like a 20mb drive in it originally. Sounded like a small jet engine. We thought we'd never need more memory... Until...
@emsquared I definitely wish LS had taken off. It was a great size overall. Easier to transport than zip disks, as you say, same look as a floppy, and if you wanted to read floppy disks, much faster as it was connected to IDE bus.
