**Development Release #1**

Kernel version	1.0
CPU architecture	x86 (16-bit)
Compile date	May 1984

Development Release #1 is an early pre-release build of Windows 1.0, compiled sometime in late May 1984. Only the Tandy 2000 variant of this build is currently known to exist, however, a PC-compatible variant would've been shipped as well.

Overview

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. The Tandy 2000 variant of this build was 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 ran from a single 5,25" floppy disk. This loaded a copy of Windows with several sample applications which could easily be loaded from there.

This build uses the .MOD extension for applications, predating the NE executable format.

-'''Windows 1.0 Tandy 2000 builds''' are a pair of early pre-release builds of [[Windows 1.0]] that were demonstrated on the Tandy 2000 Personal Computer. Photos of these builds running on said computer were featured in various computer magazines at the time. The main advantage of the Tandy 2000 version of Windows was its color support (thanks to the 2000's display adapter), as the PC version was still monochrome at the time.

-== Later build ==
+[[Category:Windows 1.0]]
-The later build is shown in an ad for the Tandy 2000, featuring Bill Gates describing the Model 2000 and various advantages of developing and using Windows on it. The ad was published in 1984-11 and 1984-12 issues of BYTE magazine<ref>https://archive.org/stream/byte-magazine-1984-11#page/n569/mode/2up</ref><ref>https://archive.org/stream/byte-magazine-1984-12/1984_12_BYTE_09-13_Communications#page/n541/mode/2up</ref>, and the 1984-11-05 issue of InfoWorld magazine.<ref>https://books.google.com/books?id=oC4EAAAAMBAJ&pg=PA1&dq=tandy+2000&hl=en&sa=X&ved=0ahUKEwj9jvrgl77hAhXtwosKHTojAJgQ6AEINTAD#v=onepage&q&f=false</ref> While it appears very similar to the earlier build, there are some notable differences which suggest this build is newer than the previous one.
-The status bar at the top was gone and button labels in the Calculator application are now vertically centered like in DR5, rather than aligned to the bottom like in the earlier build. The minimized icon at the bottom is the Spread Sheet application seen in various earlier builds. The DOS Window is again listing files on the A: drive, but this time there are also the following files that are not listed in the previous build: <code>CALENDAR.MOD</code>, <code>CALENDAR.RES</code> and <code>CALENDAR.TXT</code>. These are probably files of the old Calendar application from previous builds, which was removed by the time DR5 was made and returned in the [[Windows 1.0/Beta Release|Beta Release]], but was then redesigned before the [[Windows 1.0/Premiere Edition|Premiere Edition]].
