1570-rom.315090-01.bin
The firmware of a 1570 disk drive. The board may say "1571 disk", but the 1570 and 1571 were very similar anyway, the most remarkable difference being that the 1570 has single-sided drive mechanism.
1571-rom.310654-03.bin
The firmware of a 128D's built-in 1571 disk drive, or of a stand-alone 1571.
1571-rom.310654-05.bin
An upgrade of the above. Corrects the bug of 310654-03 that moves the R/W head between each sector when writing on the disk's top side.
1571cr-rom.318047-01.bin
The firmware of a 128DCR's built-in 1571CR disk drive.
