GIEBLER DOCUMENTATION
Ensoniq Mirage Disk Format
The Mirage has a format similar to the SQ-80 keyboard. However, the disk only contains data on one side of the disk with 80 tracks numbered 0 – 79. Like the SQ-80, each track has five 1024 byte sectors numbered consecutively from zero to four followed by one sector of 512 bytes with a sector ID of five. The following examples should clarify this.
TK SC SIZE
0 0-4 1024 data is first stored on Track 0, Sectors 0-4
0 5 512 data is next stored on Track 0, Sector 5
1 0-4 1024 data is next stored on Track 1, Sectors 0-4
1 5 512 data is next stored on Track 1, Sector 5
this process continues until...
79 5 512 the last track - Track 79, Sector 5
The diskette may contain the Operating System, six sounds configured as 3 lower-half keyboard sounds and 3 upper-half keyboard sounds and either eight short sequences or three long sequences. The first 11K of the Operating System is stored on both small and large sectors from Track 0, Sector 0, to Track 1, Sector 5. The remaining 5k of the Operating System is stored only on small sectors (Sector 5) from Track 2 to Track 10. The configuration parameters are stored on Track 11, Sector 5. The directory and the sequences are only stored on the small sectors (Sector 5) and the sound files are only stored on the large sectors (Sectors 0-4).

Mirage Directory Sectors
The directory information for the Mirage is contained in three bytes which are stored in three sectors of the diskette. Each sector contains 512 copies of the directory byte for that sector. This was done because there wasn’t any buffer space to read a whole directory sector. Therefore, the Mirage would read (or write) the sector and would use the last byte of the sector as the valid value for the directory byte. Track 32, Sector 5 contains the Sound Directory Byte. Track 33, Sector 5 contains the Short Sequence Directory Byte and Track 34, Sector 5 contains the Long Sequence Directory Byte. The directory bytes are defined as follows:
SOUND DIRECTORY BYTE SHORT SEQUENCE LONG SEQUENCE
DIRECTORY BYTE DIRECTORY BYTE
Bit 0 Not Used Bit 0 Seq. 1 Bit 0 Seq. 1
Bit 1 Sound 1 Lower Bit 1 Seq. 2 Bit 1 Seq. 2
Bit 2 Sound 1 Upper Bit 2 Seq. 3 Bit 2 Seq. 3
Bit 3 Sound 2 Lower Bit 3 Seq. 4 Bit 3 Not Used
Bit 4 Sound 2 Upper Bit 4 Seq. 5 Bit 4 Not Used
Bit 5 Sound 3 Lower Bit 5 Seq. 6 Bit 5 Not Used
Bit 6 Sound 3 Upper Bit 6 Seq. 7 Bit 6 Not Used
Bit 7 Not Used Bit 7 Seq. 8 Bit 7 Not Used
If the Sound or Sequence exists, the appropriate bit is set to one (1). If not, the bit is cleared (0).
