4 Image Storage
30FPS SCSI DISK OPTION
The 30FPS option contains three SCSI Disk Controllers and two SCSI disk
drives. The IDE drive is not present with this option. The disks are 1 GB or
larger and one is DOS-formatted with 10 and 30 MB partitions. One SCSI
controller (DOS-SCSI) performs all of the DOS functions, communicating
with the 10 MB and 30 MB partitions. The other two SCSI controllers (IP-
SCSI) transfer data to or from the Image Processor and the SCSI disks in
the non-DOS area of the disk. Image data is transferred between the
Image Processor and the IP-SCSI controllers at the 30 fps rate. Image
data is then transferred between each IP-SCSI controller and its
associated disk as 8-bit image data at approximately 3.5 MB per second.
Each IP-SCSI controller transfers image data for every other image frame.
Even numbered frames are stored on SCSI disk (1) and odd numbered
frames are stored to SCSI disk (2).
