I remember DEC calling the VAX a mainframe. The VAX 780 and 785 only had one massbus, so they didn't have the I/O of a mainframe. I don't know if latter models had more the one bus. If they did then I suppose they could be called mainframes.

Yes, it's one of the points, perhaps the main point, in what I would use as the definition of a "mainframe", channelized I/O. I remember DEC trying to call the VAX a mainframe, and it was never clear to me if it was really doing channelized I/O. Those carrying the message didn't know the meaning. (I still liked the VAX, just didn't like my peers calling it a mainframe.) ... > This is the big difference in mainframe architecture. > We should make more of an effort to get this message out. -- R;
