My recollection is different. SVC 99 (Dynamic Allocation) was a
necessary element of the TSO infrastructure. When TSO went GA, SVC 99
had to be there. TSO was available when I moved from New York to
Poughkeepsie in 1972.

In PCP, MFT and MVT, SVC 99 didn't even exist! Nor TSO.
Yep. TSO was, as I recall, *added* to MVT somewhere along the line.
And SVC 99 was not used, again, as I recall. That came with MVS or
maybe VS2?

AFAIK, TSO was always a "gennable" option of MVT.
Certainly as of MVT Rel 18 (circa 1972) and probably much earlier.
