[![John von Neumann with EDVAC/MANIAC I/IAS depending on source](https://i.stack.imgur.com/je5oK.jpg)](https://i.stack.imgur.com/je5oK.jpg)

See the image. Different sources claim that this machine is the EDVAC, MANIAC I, or IAS. 

For example, the Wikipedia page on John von Neumann has a picture of him and J. Robert Oppenheimer standing in front of this machine with the caption that it is the EDVAC.  

But the page about von Neumann's First Draft on the EDVAC has the same picture with the caption saying it is the MANIAC I. And the caption for this picture in an [ACM article](https://cacm.acm.org/magazines/2014/1/170862-actually-turing-did-not-invent-the-computer/abstract) says that it is the IAS. 

Which is it?
