Page "Commodore 1570" Paragraph 1

The Commodore 1570 was a 5¼ " floppy disk drive for the Commodore 128 home / personal computer.

It was a single-sided, 170KB version of the double-sided Commodore 1571, released as a stopgap measure when Commodore International was unable to provide large enough quantities of 1571s due to a shortage of double-sided drive mechanisms.

Like the 1571, it could read and write both GCR and MFM disk formats.
