- The Commodore 1570 is a 5¼" floppy disk drive for the Commodore 128 home/personal computer. It is a single-sided, 170 kB version of the Commodore 1571, released as a stopgap measure when Commodore International was unable to provide sufficient quantities of 1571s due to a shortage of double-sided drive mechanisms (which were supplied by an outside manufacturer). Like the 1571, it can read and write both GCR and MFM disk formats.The 1570 utilizes a 1571 logic board in a cream-colored original-1541-like case with a drive mechanism similar to the 1541's except that it was equipped with track-zero detection. Like the 1571, its built-in DOS provides a data burst mode for transferring data to the C128 computer at a faster speed than a 1541 can. Its ROM also contains some DOS bug fixes that didn't appear in the 1571 until much later. The 1570 can read and write all single-sided CP/M-format disks that the 1571 can access. Although the 1570 is compatible with the Commodore 64, the C64 isn't capable of taking advantage of the drive's higher-speed operation, and when used with the C64 it's little more than a pricier 1541. Also, many early buyers of the C128 chose to temporarily make do with a 1541 drive, perhaps owned as part of a previous C64 setup, until the 1571 became more widely available. The drive uses the CPU MOS 6502, floppy controller WD1770 or WD1772, I/O controllers 2x MOS Technology 6522 and 1x MOS Technology 6526. (en)
- La Commodore 1570 fue una unidad externa de disquete de 5,25 pulgadas creada para el ordenador doméstico Commodore 128, aunque puede utilizarse con los Commodore 64. Fue lanzado por Commodore International como un sustituto temporal de la Commodore 1571 cuando vio que no contaba con suficiente suministro de mecanismos de doble cara para cubrir la demanda. Su placa madre es la misma que la de la 1571, pero con una ROM más avanzada que implementa varias correcciones de errores que tardarán en aparecer en la 1571. El mecanismo de la unidad es la de una Commodore 1541c (básicamente, una 1541 dotada de detector de pista cero), al igual que la caja y la fuente de alimentación. Es capaz de leer y escribir discos formateados en y MFM. Su DOS 3.0 incluye el modo de ráfagas para transferir datos a un Commodore 128 a mayor velocidad que una 1541, y puede leer y escribir discos CP/M de simple cara, principalmente :
* IBM PC CP/M-86
* Osborne 1
*
* Kaypro II,
* CBM CP/M FORMAT SS Aunque es compatible con el Commodore 64, éste no es capaz de sacar partido de los modos rápidos del disco, por lo que a ojos del consumidor es una 1541 sobrepreciada, que además tenía problemas con determinadas protecciones. Además muchos de los primeros compradores de un Commodore 128 optaban por usar una 1541 proveniente de un equipo anterior, mientras esperaban que la 1571 estuviera más disponible. (es)
- Il Commodore 1570 fu un'unità a dischi floppy della Commodore Business Machines Inc., prodotto per il Commodore 128. Utilizzava dischi floppy da 5¼", e venne creato per cercare di arginare la crescente richiesta del Commodore 1571, a causa della carenza di produzione della meccanica per i dischi a doppia faccia.
