In the bus protocol context of master vs slave: Some combination of bus-controller works ok, bus-arbiter, or bus-writer vs bus-reader or bus-listener, or bus-consumer. We also have the idea of having two units 'slaved' together. Which I guess would just be 'synced' or 'chained' though 'chaining' in this case is still probably the same metaphor as 'slave'. Overall I'm not so big on these sorts of efforts. The euphemism treadmill has been going on forever with little apparent impact on the underlying inequities of the world. To me it feels like the act of changing the language is a way to feel good about doing something without actually doing the hard work of changing the actual beliefs and actions of racism. That said I don't think it matters all that much: terminology falls in to and out of fashion all the time, and we end up forgetting where most of it comes from (which could be used as an argument for either side). So uhh long-live whatever!
