Things to Know
DGT2IIXG and DGT7 appear with both early DKC500R (4 Mbit program ROM) and later DKC500RW (8 Mbit / PRO program) controller variants; check the actual control unit label when identifying these systems.
If replacing the floppy disk drive, use the model-specific slim drive listed in my Nalbantov guide. My DKC-500-series installation guide covers this procedure for the DKC500R, DKC500RW, and DKC500RXG.
A DKC-850 can replace this controller, but the installation requires the correct model-specific harness—not an ordinary VGA cable. My DKC-850 conversion-cable guide explains the original Yamaha cable and the replacement adapters made by Richie Hayes. On a PRO piano, the replacement operates in STANDARD mode and does not preserve PRO/XP recording.
If a computer reports an original Yamaha Disklavier floppy as unformatted, do not format it. My Disklavier floppy-recovery guide explains why this happens, and my tested USB floppy-drive guide identifies hardware that can read 720 KB/2DD disks.
