Nonetheless, manufacturers were reluctant to remove the floppy drive from their PCs, for backward compatibility, and because many companies' IT departments appreciated a built-in file transfer mechanism that always worked and required no device driver to operate properly. One financially unsuccessful attempt in the late 1990s to continue the floppy was the SuperDisk (LS-120), with a capacity of 120 MB (actually 120.375 MiB), while the drive was backward compatible with standard 3½-inch floppies. Mass backups were now made to high capacity tape drives such as DAT or streamers, or written to CDs or DVDs. With the arrival of mass Internet access, cheap Ethernet and USB keys, the floppy was no longer necessary for data transfer either, and the floppy disk was essentially superseded. Toward the end of the 1990s, software distribution gradually switched to CD-ROM, and higher-density backup formats were introduced (e.g. Many home computers had their primary OS kernels stored permanently in on-board ROM chips, but stored the disk operating system on a floppy, whether it be a proprietary system, CP/M, or, later, DOS.īy the early 1990s, the increasing size of software meant that many programs were distributed on sets of floppies. Before the popularization of the hard drive for PCs, floppy disks were often used to store a computer's operating system (OS), application software, and other data. Floppy disks are read and written by a floppy disk drive or FDD, the latter initialism not to be confused with "fixed disk drive", which is an old IBM term for a hard disk drive.įloppy disks, also known as floppies or diskettes (a name chosen in order to be similar to the word "cassette"), were ubiquitous in the 1980s and 1990s, being used on home and personal computer ("PC") platforms such as the Apple II, Macintosh, Commodore 64, Amiga, and IBM PC to distribute software, transfer data between computers, and create small backups.

I'll try to attach a pic but never did this before so may not work. I don't really want to go out and find a 110 disconnect box! Should I instead connect the black to one line/load side of the pull disconnect and the white neutral to the other side so that when the disconnect is pulled then both the black and white side are disconnected………? Suspect this will work functionally but doubt it's code. HDepot guy told me to just use one side of the pull disconnect terminals for the black and hook the 2 grounds and two white neutrals to the ground lug…. NO white neutral involved.īUT the question is… When using this box for a 110 hookup (1 blk, 1 white and 1 bare ground) how do you wire. The 220v one has 2 sets of line/load terminals for the normal 2 black hot wires to make up normal 220v's…… and a ground lug below the above line/load pull disconnect terminals for the bare ground.įor wiring in a 220 unit this is pretty straight forward….The 2 line blacks in and 2 load blacks out with the bare ground to ground lug. Couldn't locate a 110 Disconnect box so using a 220v one.
