Mac OS 8.7 got rebranded as OS 9.0. 
Still pretty cool to have a beta of the OS. I have a copy of 8.2 around somewhere. But as beta software, the quality and stability is poor, and not something I would want to use for anything other than experimentation. I think the original poster in this thread was interested in picking the right OS for a PowerBook 1400, so you can assume that person wants something stable.
Peace,
Drew
