Turbo Pascal version 1.0 - The Turbo Pascal release dates

Posted by on in Blogs
It started on November 20, 1983. The release of the first version of Turbo Pascal.  Twenty Five years ago this month.  There are many release milestones for our family of products that are all a part of "The World of Delphi" - including Turbo Pascal, Turbo Pascal for the Macintosh, Turbo Pascal for Windows, Turbo Pascal for the Amiga, Delphi, Kylix, and Delphi Prism.

Wait!  Did David I. just mention Turbo Pascal for the Amiga?  Yes, the product was in development.  The development system was a Sun 2 Workstation (Motorola 68010).  We had a couple of "prototype" Amiga's that were really just simple boxes with motherboard, cards, connectors and a reset button.

Along the way we also released Toolboxes and Tutors for Turbo Pascal.  Philippe Kahn wrote the MicroCalc spreadsheet example that shipped with Turbo Pascal version 1.0.  Philippe understood that one of the main ways we learn programming is to read example source code.  The Turbo Tutor and the Toolboxes contains lots of source code.
