IBM Mainframe Emulation: Reloaded
December 22, 2008 In the April/May 2007 issue of z/Journal, the article "The State of IBM Mainframe Emulation" detailed several software emulation approaches for smaller IBM mainframe customers.

The article also discussed some ongoing legal actions surrounding these offerings. These issues meant that the mainframe emulation world was in a state of flux, with accompanying Fear, Uncertainty and Doubt (FUD) for smaller mainframe customers.
This article provides an update on these products. Significant events have transpired, with a mix of good news, bad news, and the unknown.
