Version History
Version 1.0, Released on May 13, 1987, offered the first integrated edit-compile-run development environment for C on IBM PCs. The software was, like many Borland products of the time, bought from another company and branded with the "Turbo" name, in this case Wizard C by Bob Jervis (Borland's flagship product at that time, Turbo Pascal, which at this time did not have pull-down menus, would be given a facelift with version 4 released late in 1987 to make it look more like Turbo C.) It ran in 384 kB of memory. It allowed inline assembly with full access to C symbolic names and structures, supported all memory models, and offered optimizations for speed, size, constant folding, and jump elimination.
Version 1.5, in January 1988 was an incremental improvement over version 1.0. It included more sample programs, improved manuals and bug fixes. It was shipped on five 360 KB diskettes of uncompressed files, and came with sample C programs, including a stripped down spreadsheet called mcalc. This version introduced the
Version 2.0, in 1989 was released was in late 1988, and featured the first "blue screen" version, which would be typical of all future Borland releases for MS-DOS. The American release did not have Turbo Assembler or a separate debugger. (These were sold separately as Turbo Assembler.) Turbo C, Asm, and Debugger were sold together as a suite. This seems to describe another release: Featured Turbo Debugger, Turbo Assembler, and an extensive graphics library. This version of Turbo C was also released for the Atari ST, but distributed in Germany only.
Note on later releases: The name "Turbo C" was not used after version 2.0, because with the release of Turbo C++ 1.0 with 1990, the two products were folded into a single product. That first C++ compiler was developed under contract by a company in San Diego and was one of the first true compilers for C++ (until then, most C++ work was done with pre-compilers that generated C code). The next version was named Borland C++ to emphasize its flagship status and completely rewritten in-house, with Peter Kukol as the lead engineer. The Turbo C++ name was briefly dropped, eventually reappearing as Turbo C++ 3.0. There was never a 2.0 of the Turbo C++ product series.

Borland split the product (and later Pascal) in two lines, one for beginners and one for professionals. At first they were called "Turbo and Turbo Professional, later simply have "Turbo" and "Borland". They developed C++ to 1996 in these two lines next to the version of Turbo C++ 3.0 and Borland C++ 5.0. As with Turbo Pascal, there was also a Turbo C++ for Microsoft windows, which reached version 4.5.
Turbo C for the Atari ST ended with version 2.0. The program was not maintained by Borland, but the product was sold and renamed PureC.
From 1996, Delphi became Borland's principle and highly successful Pascal toolkit. A similar release based on C++ became Borland C++Builder, which replaced Borland C++.

Famous quotes containing the words version and/or history:
“If the only new thing we have to offer is an improved version of the past, then today can only be inferior to yesterday. Hypnotised by images of the past, we risk losing all capacity for creative change.”
—Robert Hewison (b. 1943)
“There is nothing truer than myth: history, in its attempt to “realize” myth, distorts it, stops halfway; when history claims to have “succeeded” this is nothing but humbug and mystification. Everything we dream is “realizable.” Reality does not have to be: it is simply what it is.”
—Eugène Ionesco (b. 1912)
