Windows 1.xx

Screenshots of the boot screen of Windows 1.xx and Paint were shown in a flyer promoting the Tulip PC extend computer system. Based on the file dates, this build has been compiled around 1985-09-03.

This build was eventually found and released to BetaArchive on 2019-03-02. This build contains a  file in Disk 1, but Tulip Computers didn't ship the Windows Write disk with this build by default and a two-disk update set was required to install the Windows Write component for this build.
