 * Not to be confused with Windows Beta V1.03.04.

Windows 1.03.04 is a port of Windows 1.03 made by Digital Equipment Corporation (DEC) for their Rainbow 100-B computer.

It is currently available in a form of two pre-installed copies, though an original 5,25" installation media is supposed to exist.

Installation
Use the MAME emulator running the Rainbow 100-B machine with 512k or more memory configured.

Step-by-step

 * 1) Create a 10MB or 20MB CHD hard disk image with standard CHS values using the   tool.
 * 2) Boot the machine, open the main configuration menu using the Tab key:
 * 3) * In DIP Switches, enable  and
 * 4) * Set your CHD image to  (File Manager menu)
 * 5) * Set the MS-DOS 3.10b boot disk to
 * 6) * Set the Winchester Utilities (WUTIL) disk image to  and reboot the machine
 * 7) Run the aforementioned utility  to prepare your CHD image by using "format and initialize hard disk" and following on-screen instructions.
 * 8) Partition and format the hard drive by using ,   and   utilities.

Windows installation
This OEM version was most likely never officially distributed on floppy disks, and is only available as a pre-installed copy. Its files are compressed in ARC archives. To extract them, you must use an utility like PKXARC.

For extracting the archives and copying them into the Rainbow-specific floppy disk images, you need the 86Box or PCem emulator with an existing installation of MS-DOS (version 3.30 recommended) with two 5.25" 360KB floppy drives configured. You also need to make 5,25" 360KB floppy disk images containing every single ARC archive, and find several Rainbow single-sided 5,25" 400KB disk images where to put the extracted Windows files.

Using RX50DRVR and PKXARC

 * 1) Download RX50DRVR and PKXARC.
 * 2) Run your MS-DOS machine.
 * 3) Copy the files from the floppies to C:.
 * 4) Add the following line into your   file:.
 * 5) Reboot the system.
 * 6) Insert the Rainbow floppy disk into drive A:, and a floppy with the ARC archive into drive B:. Please note that RX50DRVR will automatically assign specific drive letter for the Rainbow floppy disks. You can access them as drive D:.
 * 7) Type  . This will initialize your Rainbow floppy disk for the first use.
 * 8) Type  . This will extract the Windows files from the ARC archive into the floppy disk.
 * 9) Follow these steps with every other ARC archive.

There is a chance that there will be not enough space on the floppy disks for the Windows files. In this case, you have to extract the ARC files with an extracting utility for Windows and manually add the missing files to the 5,25" 360KB floppy disk images. Then you can copy the files from with the  command.

Copying Windows files

 * 1) Run your Rainbow 100-B machine.
 * 2) Set the floppy disk with the Windows files into "floppydisk2".
 * 3) Type   and follow all these steps with every other floppy disk.
 * 4) Reboot the system.
 * 5) Press "A" to boot from the MS-DOS 3.10b floppy disk.
 * 6) Navigate into drive E:.
 * 7) Type.
