National Instruments NB-GPIB/TNT IEEE 488 Interface Apple Macintosh NuBus Rev D

The National Instruments NB-GPIB/TNT is an IEEE-488 (GPIB) interface card for Apple Macintosh computers equipped with NuBus expansion slots. Built around National Instruments' TNT (Transform Network Technology) GPIB controller chip, it provides a high-performance instrument bus connection between NuBus-based Macs and IEEE-488 compatible test and measurement instruments. This is Revision D of the card, copyright-dated 1993 per the on-board label.

Applications

The NB-GPIB/TNT was designed for Apple Macintosh systems using the NuBus expansion architecture, which Apple used from the mid-1980s through the mid-1990s in the Macintosh II series, Quadra, and Power Macintosh lines (the NuBus architecture was retired with the transition to PCI around 1995). In that era, scientists and engineers frequently used Macs as instrument controllers in laboratory and test environments, and the NB-GPIB/TNT provided the IEEE-488 bus link between the Mac and benchtop instruments — oscilloscopes, signal generators, power supplies, spectrum analyzers, and other GPIB-equipped devices — allowing data acquisition and instrument automation via National Instruments' NI-488.2 and LabVIEW software. Today, this card is sought by those maintaining legacy NuBus Mac-based test systems, vintage instrument automation setups, or classic Macintosh computing collections.
