from
Wikipedia
The 1570 utilized a 1571 logic board in a cream-colored Commodore 1541 case with a drive mechanism similar to the 1541 except that it was equipped with track zero detection.
Like the 1571, its built-in DOS provided a data burst mode for transferring data to the C128 computer at a faster speed than a 1541.
