Developer Release 5 is a pre-release version of Microsoft Windows 1.0. It was shipped to testers in around November 1984.
Machine requirements
This pre-release version supports IBM and COMPAQ personal computers with a graphical display adapter (either a Hercules or CGA display adapter), one floppy disk drive, and a hard disk drive.
Hercules support
While this version provides support for Hercules display adapters, only the files necessary to provide CGA support are copied by default. In order to copy the Hercules files, you will need to either modify the INSTALL.BAT
file to copy the Hercules files by default, or copy the Hercules files later from the floppy disks yourself.
For Windows to copy the Hercules files by default, you will first need to make a backup copy of the first disk, and then make the following changes to INSTALL.BAT:
- Change the following line:
copy a:ibmcolor.cin %1\windows\test\cursor.exe copy a:ibmcolor.din %1\windows\test\display.exe
- To the following:
copy a:hercules.cin %1\windows\test\cursor.exe copy a:hercules.din %1\windows\test\display.exe
You can also rename or remove the CGA files and copy the Hercules files from the disk to the directory on your hard disk where Windows is installed.
