When I started with IBM in early 1967 DOS and TOS were contemporaries.
I never remembered anything about TOS having been available before DOS.
I started in the Chicago Distribution office and the Sears National
Account was the tail that wagged the dog there. The Sears team, in
order to demonstrate multi-programming, used a TOS system since there
were too few 2311 disk drives around at Sears and MFT and certainly MVT
could not be expected to run in the mid-60's.
As far as what Phil is referring to, I don't have the foggiest. I
seldom have the desire or inclination to fight my way thru blogs and the
S/360-30's that I supported for a few years were not even close to being
super-computers. By my calculations, they were about 18KIP machines.
