The OVLBI VME rack contains the station computer (MVME 147), MCB interface (MVME 331), two Decoder boards and the OVLBI optical modum. The MVME computer also includes a floppy disk drive and scci interface hard drive.

The station computer controls the scheduled execution of station commands. VxWorks is the real-time operating system, and all station control code is written in C. The station computer also supports the operator interface, real-time data logging and antenna pointing.


The Decoder is built on two 6U wire wrap cards. The interface to the station computer is via the VME bus.
