This PC I bought somewhere in Noord-Brabant in 2013. The owner did not know that it contained an installation of Windows 1.0 but while I was testing the PC I saw some Win-files when I executed the dir command on the computer.
When I was at home and tested the win command it started Windows 1.0, a fantastic surprise!
Now in 2018 I still own this computer originally from 1987. It’s 31 years old.
Later I ordered these Windows 1.03 5,25 inch floppies to complete this system with the original software. These floppies are containing the Dutch version of Windows 1.03 what is really rare.
