Thanks to Twitter, here’s an interesting footnote in computing history.
As A/UX development was winding down, Apple was working on another project called the Macintosh Application Environment. This was an emulator that allowed users to run Mac software under Sun’s Solaris or Hewlett Packard’s HP-UX. A great deal of A/UX technology went into the design of this ill-fated product. This page is a pictorial tribute to the Macintosh Application Environment, running under Solaris 8 on an Ultra 10 workstation. If you want to try the MAE, you’ll need a Sun box running Solaris 9 or below – The software does not appear to work under Solaris 10.
This is absolutely fascinating, and I had no idea this existed.
