Microsoft Systems Journal, the first programming publication from Microsoft covered MS-DOS internals and progressed to cover the workings of Windows.

Microsoft Systems Journal was the first programming publication from Microsoft.

Predating the Windows operating system, MSJ covered MS-DOS internals beginning in 1986.

It progressed to cover the workings of Windows so that programmers could write applications for the then-new operating system. MSJ saw the evolution from MS-DOS to Windows 1.0, all the way up to Windows 2000 before merging with Microsoft Internet Developer to form MSDN Magazine in March 2000.

Travel back in time to find rare tools and review content dating from 1992 onwards that is still available here.... Microsoft Systems Journal

interesting stuff thanks

You are very welcome.

Incidentally there are some resources that date back to 1986.

For those who still dabble with 16bit DOS systems, you should definately find something new to you here.
