Very cool! So that would have been for Windows 2.0 or 2.1, as
Windows 3 wasn't released until 1990.
That was the first version of Windows I worked with. I was working at the US Federal Aviation Administration at the time and implementing a new desktop environment for about 500 users there that was based on Windows 2.
I was so happy when we went to Windows 3 and ultimately Windows for Workgroups 3.11. Networking in Windows 2 was a real PITA.
I also got to implement Microsoft Word for Windows 1.0. We've really come a long way since then.
