Development Release #1 is one of the earliest pre-release builds of the Microsoft Windows operating system, compiled sometime in May 1984. It was demonstrated on the Tandy 2000 personal computer.
Background
The Tandy 2000 was an Intel 80186-based computer. Since the 80186 processor was not fully compatible with the IBM PC and compatibles, this created compatibility issues dividing it from other machines of the time. This build was most likely specifically designed for the Tandy 2000 personal computer, including the Intel 80186 processor and also the high resolution graphics (640x400 screen resolution at 16 colors) used by the machine itself.
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.
It also predates NE and uses the .MOD
extension as the main executable format.
