    El 1541 tenía un precio de US$400 cuando fue introducido en el mercado. Una C64 con un 1541 costaba alrededor de $900, mientras que el Apple IIsin unidad de disquetes costaba $1295. La primera unidad 1541 producida en 1982 estaba etiquetada en el frente como VIC-1541 y tenía una carcasa de color blanquecina para que coincida con el VIC-20. En 1983,...

    Todos, excepto los primeros modelos 1541 no II, pueden usar el mecanismo Alps o Newtronics. Visualmente, los primeros modelos, de la denominación VIC-1541, tienen un color blanquecino como el VIC-20 y el VIC-1540. Luego, para que coincida con el aspecto del C64, CBM cambió el color de la unidad a marrón-beige y el nombre a Commodore 1541. Las numer...

    La Commodore 1570 es una actualización del 1541 para usar con el Commodore 128, disponible en Europa. Ofrece capacidad MFM para poder trabajar con los discos de CP/M, velocidad mejorada y un funcionamiento más silencioso, pero solo se fabricó hasta que Commodore puso en marcha sus líneas de producción con el 1571, la unidad de doble cara. Finalment...

    The Commodore 1541 is a floppy disk drive which was made by Commodore International for the Commodore 64, Commodore's most popular home computer. The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-kilobyte drive for 5¼" disks. The 1541 directly followed the Commodore 1540. The disk drive uses group coded recording and cont...

    The 1541 was priced at under US$400 at its introduction. A C64 plus a 1541 cost about $900, while an Apple II with no disk drive cost $1,295. The first 1541 drives produced in 1982 have a label on the front reading VIC-1541 and have an off-white case to match the VIC-20. In 1983,

    All but the very earliest non-II model 1541s can use either the Alps or Newtronics mechanism. Visually, the first models, of the VIC-1541 denomination, have an off-white color like the VIC-20 and VIC-1540. Then, to match the look of the C64, CBM changed the drive's color to brown

    The Commodore 1570 is an upgrade from the 1541 for use with the Commodore 128, available in Europe. It offers MFM capability for accessing CP/M disks, improved speed, and somewhat quieter operation, but was only manufactured until Commodore got its production lines going with the

    The 1541 does not have DIP switches to change the device number. If a user added more than one drive to a system the user had to open the case and cut a trace in the circuit board to permanently change the drive's device number, or hand-wire an external switch to allow it to be c

    The 1541 uses a proprietary serialized derivative of the IEEE-488 parallel interface, which Commodore used on their previous disk drives for the PET/CBM range of personal and business computers, but when the VIC-20 was in development, a cheaper alternative to the expensive IEEE-4

    IEEE Spectrum in 1985 stated that: The one major flaw of the C-64 is not in the machine itself, but in its disk drive. With a reasonably fast disk drive and an adequate disk-operating system, the C-64 could compete in the business market with the Apple and perhaps with other business computers. With the present disk drive, though, it is hard-presse...

    Early copy protection schemes deliberately introduced read errors on the disk, the software refusing to load unless the correct error message is returned. The general idea was that simple disk-copy programs are incapable of copying the errors. When one of these errors is encountered, the disk drive will attempt one or more reread attempts after fir...
