From BetaArchive Wiki
Development Release #2 (DR2) demonstrated on the Tandy 2000 personal computer

Development Release #2 is an early pre-release build of Microsoft Windows 1.0, demonstrated on the Tandy 2000 personal computer.

For some reason, the Clipboard app has been removed, however, it was later re-added in the next build.

Files

Just like the previous build, this build was launched from a file called DEMO.BAT and was intended to be run from a single floppy disk. This loaded a copy of Windows with several sample applications which could easily be loaded from there.

This build also predates NE and uses the .MOD extension as the main executable format.
