Not to mention that PDP-11s could boot from tape pretty much from day 1. Yep - but it was a different target customer originally. The 11 was the take over the laboratory systems that the 8 had. And many of those systems did not have rotating storage in them. Cassette tape was not unheard of (and the PDP-11's could boot from cassette tape). The Vax was envisioned as a system that could move into the same class of customer and (use) as the 10 (and this start the 36/32 bit war). But both vax and 10's were supposed to the computing hub. As I have said before, the 750 was a part of that war between LDP (laboratory data products) enterprise folks. It's a big reason why Masscomp was formed. Dave Cane used to say that the MC-500 was the computer he had always wanted the 750 to be. That said, you're right, at some point -- network boot because de rigor but I >>think<< that was all post BI systems and long after I was tracking the vax closely.
