Commodore Business Machines's "advanced" diskdrive for the C128. It was the double-sided version of theCommodore 1570 disk drive but, unlike the 1570, worked quitewell.The 1571 supported "burst mode" loading when used on a C128in native mode, which increased the transfer speed from 1541speed to about three kilobytes per second (about a 10-foldincrease). The 1571 could be told to emulate a 1541 for usewith a C64 or 1541 disks.Bugs in early releases of the 1571 ROM affected access tothe second side of the disk.
