I dunno – there’s something about the sheep welcoming the 7070 that struck me funny.  <grin>

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. "

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.
