Disk Functions
The DX7 II provides an onboard disk drive. This drive uses 3.5 inch double-sided
FD
double-density floppy disks. You may store data in one of three formats on disk. These
include: Internal memory (INT), Cartridge memory ( C R T), and 11IDI Data Recorder
(MD R).
Once data has been stored in one of these formats, it may not be directly sent to another
data type. In other words, if you store the contents of the internal memory to an INT f i l e,
you cannot directly output that fi l e to a RA M cartridge. You must first load the data into
Internal Memory, refer to the section entitled " Loading Internal Memory". It may then be
saved to a RAM cartridge. Likewise, a C R T f i l e must go to a RAM cartridge be fore being
loaded into the Internal Memory. Be sure you check the correct format (INT, C R T, or
MD R) when looking for a f i l e on disk.
Data is stored in f i l es on a disk. Each file has a number, a name, and a type (either INT,
C R T, or MD R). This helps you (and the DX) keep track of data. Depending on their size,
99
you may store up to f i l es on one disk.
A Memory Protect tab (see diagram below) may be used to protect valuable data from
accidental erasure. The tab must be down in order to format or write to a disk.
