Macintosh AV Series: Video Features and Subsystems -- the MUNI chip
Power Macintosh 6100, 7100, 8100: Description of Integrated Circuits -- the BART chip
More details on these Apple Macintosh models, for anyone who's interested: apple-history.com / specs for every apple computer, established 1996
Apple's 1993 Centris 660AV, Quadra 660AV and Quadra 840AV had a chip called the Macintosh Universal NuBus Interface for communicating with NuBus plug-in cards. Its acronym is MUNI, the usual abbreviation of the San Francisco Municipal Transportation Agency.
It likely inspired the name of a successor chip that did NuBus interfacing in Apple's 1994 PowerMac 6100, 7100, and 8100, the BART chip. I haven't been able to find that name's canonical interpretation, however. BART = Bay Area Rapid Transit, which also serves San Francisco.
Apple soon moved from NuBus to PCI, which does the same thing, but which was more widely used.
