WORKSTATION CONFIGURATION 
ARIES-II systems fall into three classes, "Single Processor" 
Systems, "Peripheral Workstation" systems, and "Network Workstation" 
Systems. Within each class a wide variety of options is available 
and moreover a Single Processor system is generally upwards compati- 
ble to a workstation system, and a Peripheral Workstation system is 
upwards compatible to a Network Workstation system. 
Single Processor System A functional block diagram of a 
Single Processor system is shown in Figure 2. Here the single 
Computer Subsystem is responsible for all processing activity. It 
controls movement of image files between the Image Storage Node and 
any of the optional peripherals or the Image Display. It -performs 
image processing on a disk-to-disk basis by transforming source 
image files on the Image Storage Node to destination image files 
also on the Image Storage Node. It fields all operator interaction 
with the system. 
The Single Processor systems can have one of several Computer 
Subsystems (CSS; from: DEC LSI 11/23 to VAX 11/780). Along with sup- 
porting the Image Display Subsystem, the single processor systems 
also support a variety of peripherals.

Peripheral Workstation Configuration A functional block diagram of a 
typical Peripheral Workstation ARIES-II configuration is shown in Figure 3. The 
diagram shows an Image Analysis Workstation comprised of an optional Image Stor- 
age Node, Peripherals and an Image Display Subsystem, linked via an interface to 
a Host Computer bus. Each Image Analysis Workstation (and there can be more than 
one) is a dependent ARIES-II configuration. The host computer in this configura- 
tion is usually a larger camputer, such as a PDP 11/44 or one of the VAX series.
