Closer to the machinery, VME based computers contain the interface hardware, and run most real-time tasks under the VxWorks operating system. Hardware interfaces are provided to connect the telescope servos and instrumentation to the computer systems.
The real-time needs of the telescope are met using Motorola MVME-167 68040 based SBC's. Twelve of these run M&C code, while 2 others are supplied with the contractor's servo system. See Table 2 for the features found on the MVME-167.
