As a long-time fan of GeoWorks Ensemble (now Breadbox Ensemble), a DOS based graphical user interface and office suite popular in the 80s, I've run it under a variety of operating systems and emulators over the years. You see, Ensemble requires an underlying operating system to provide a DOS compatible file system, not unlike early versions of Windows that required DOS. [...] With the release of eComStation 2.0 I thought I'd revisit the challenge of getting Breadbox Ensemble running under OS/2 again [...] but to add a further twist, since I didn't want to do this on a dedicated machine, I chose to see if I could get things running under VirtualBox.
