The 7070 was announced in Sept. 1958, but did not ship

According to IBM's DPD Chronology for 1959:
"On August 3, DPD introduces the IBM Datacenter -- facilities in which
customers rent the use of IBM 7070 systems by the hour and supply their
own programmers and operators. DPD foresees a nationwide network of 25
to 30 Datacenters in major cities, with the first three located in New
York City, Chicago and Los Angeles. "
The first IBM computing device to use transistors and
no vacuum tubes
was the 608 calculator, shipped in December 1957. IBM's first
transistorized computers were the 7090 (36-bit scientific,
transistorized version of 709) shipped in November 1959, and the
1401, shipped in early 1960, before the 7070.
As a matter of fact, here's a 7070 on its way to an installation in
Naples in 1959:

And I *did* specify computer, not calculator with regard to transistors.
So who you gonna believe--a photo taken in 1959 or some guy writing 27
years later saying it didn't exist? Perhaps they've got the 7070
confused with the 7074.
