Will/can it work with a 30 year old quad receiver? Not really.
I wasn't really recommending he use a passive network or other means so he could use a center channel, instead I actually mentioned the quality of the Bose and the old ways of genrating a center signal because I got distracted by the mention of old audio gear and got off-topic!
Most receivers from that era decoded QS, SQ and CD4 (if I remember correctly). No center channel info is extracted (nor was it intended).
Your memory is correct
and no, no center was used with those music-oriented systems and in fact, many audio engineers to this day dislike using one with their multichannel music mixes.
As far as the 901s for HT use, to be perfectly frank I would not use them because of their huge and rather "ambient" soundfield they produce and even if a center was used with them (and an A/V receiver found that could accomodate the active EQ, proably impossible these days), the left and right front channel info on the soundtrack would be coming at the listeners from multiple directions, imo leading to a confusing image+audio experience.
