The 3B2 was, well, if I'm being nice, an also ran. It was a thing but it was never the thing. I've run at least one of the lower end models, it worked but it was behind the other systems I ran. Cool that they did it, but like many attempts, not enough ahead. I have very fond memories of the BLIT terminals, I just liked how much you got out of a serial cable. Way, way more than anyone else imagined.
