At the time, LabVIEW was only available on the Macintosh, making this the computer of choice. The data acquisition hardware can be a stand- alone device, e.g., a GPIB scope, or a module in a crate, e.g., a VME digitizer. Commercially available and LabVIEW sup- ported interface cards connect the Macintosh to the device or crate. While this is indirect, as opposed to using the Acnet protocol, the 1 Operated by the Universities Research Association Inc., dures are represented as simple lists with items to complete. These checklists are available for each transition to the next phase and each change within a phase.
Additional explanations are available for people using the list for the first time.

Adding the Acnet interface to the LabVIEW program typically takes less than a day unless an intrinsic control is required using a custom-made console application. Any major change that the developers make must be docu- mented according to the commissioning change list unless the change is irrelevant to the operators or programmers of the console application. This judgment is left to the developers to avoid too much paper work while an error at this stage would not halt accelerator operations. Any significant change must be noted in the IB and the version number of the software must be updated.
