It seems to be saying that the System/360 was the first mainframe. What is the definition of "mainframe" being used here?

Apperantly someone doesn't consider the 709, 1620, 1401, 7090, 7094, 7080, 7040, 7044 or 7030 to be significant mainframes.

Can't for the life of me see why. :-)


Never attribute to careful reasoning what can be explained by simple ignorance. Some relative newbie to computers read "birth of S/360" and "mainframe" and just assUmed it was the first mainframe.

I would think the first machines to be worthy of the mainframe moniker would have perhaps been the Z3 by Zuse in Germany around 1941, followed a couple of years later by the Mark II and ENIAC in the U.S. and Colossus in England. Of course the U.S. news media only covered U.S. developments for decades, and information about Colossus wasn't even generally available until the project was finally declassified in the 1970's.
