There was a week in January 2014 where I participated in three meetings/events where emulation came up as a digital preservation solution. Emulation has really hit its stride, 20 years after I first heard about it.
An emulator is an environment that imitates the behavior of a computer or other electronic system. In recent years, this has come to be known as a Virtual Machine, which is a recreated computer environment — from the operating system to the video drivers and software — that can be run in an interactive manner using current technology, including a web browser in some instances.
I was very much the fan of collecting hardware for digital preservation, until I participated in the Library of Congress Preserving.exe meeting in May of 2013. I wrote about my own conversion to Team Emulation in an earlier post on this blog., and my colleague Bill Lefurgy responded to my post with a post of his own. (That said, we still need vintage hardware to read older media to bring operating systems and software into emulation environments.)

Don’t let some of the early dates fool you – this issue was debated in just as lively a way 15 years ago as it is now.
