ED never caught on, I suspect because of very little bang-for-the-buck. The disks never came down very far off the $5/disk level. Too little, too late. As far as high-density floppies, there were many contenders, all failing to capture significant market share. I still have a pile of Caleb "IT" drives and disks offering 144 MB, for example. However, the LS120 drives do have a practical use--I put them in later systems with IDE connectors that would otherwise go unused (the primary-use connections are SATA), when I'm building a system into an older case that still has a place for a 3.5" floppy. Linux still recognizes the the drive. --Chuck
