Mainframe, MVS and zOS Discussion

Hi,

I had been looking for the documents on Proteus(Fundi). And the only relevant post, on the intrnet, I could find was the below one:What is Proteus(Fundi)? - Mainframe, MVS and zOS Discussion (zmainframes.com)Are there any more documentation someone can share please? Or direct to a link? This would be a great help. 
 

Thank you enrico, I figured that too but rocketsoftware website does not really tell if they have discontinued the software or rebranded it. As I could not find any direction on documentation on the site. 

I think this software has been discontinued. 

I also think so. I have searched a lot, but I cannot find a hint for it.
