quickring started as an offshoot of the fabled futurebus project, which started in the late 1970s under the aegis of the ieee. the futurebus process quickly bogged down, and concluding it was doomed, several of the main designers left the effort in 1987 to try again on smaller projects, leading to both quickring and sci. in the case of quickring the main proponent was paul sweazey of national semiconductor, who had hosted futurebus's cache coherency group. sweazey left national semiconductor and moved to apple computer's advanced technology group, where the new system was developed.
