SuperCard
From Wikipedia, the free encyclopedia
SuperCard is a high-level development environment that runs on Macintosh computers, under OS 8 and 9, and OS X. It is inspired by HyperCard, but includes a richer language, a full GUI toolkit, and native colour. (Colour required one of several add-ons in HyperCard, from Apple or third-parties.)
On the Mac OS or OS X desktop, however, projects can be run standalone, using a "compiler". (This is not a real compiler but combines an interpreter with the project's code.) To emphasize this, in SuperCard 3.0 the standard application icon was blue instead of grey.
The programming language used by SuperCard is called SuperTalk, and is largely based on HyperTalk, the language in HyperCard. SuperTalk has many features that allow creation of rich applications. This includes functions to run OSA-based scripting languages such as AppleScript, and shell commands. The language can be extended with so-called externals, chunks of compiled code that can be called from SuperTalk.

[edit] History
[edit] The early years
SuperCard was first created by Bill Appleton at Silicon Beach Software in 1989. In 1990, Silicon Beach was acquired by Aldus Corporation. Aldus released version 1.6 of SuperCard which brought support for AppleEvents, enhanced graphic capabilities and several other improvements.
[edit] Mid-1990s
In February 1994, Allegiant Technologies of San Diego bought SuperCard. Allegiant released several versions of the software, and even won the 1995 MacUser Editor's Choice for Best New Multimedia-Authoring Application. Version 1.7 of SuperCard, which was released in June of 1994, included several important enhancements, including QuickTime support and switch statements. In December of the same year, version 2.0 was released. This was the first PowerPC native version, which made it a lot faster than previous versions on newer machines. Also, this version introduced an application called Standalone Maker, which builds true Macintosh programs out of SuperCard projects, without any need for a player program.
[edit] Late 1990s
Several versions of SuperCard were released thereafter, that included features such as support for full 24-bit color and improvements of the filmstrip feature. In early 1996, a new companion product called Marionet was released. This add-on allowed projects to communicate over local networks or the Internet. 20 months thereafter, the third version of SuperCard was released. This new version sported a new project file format supporting user properties, and a completely new Project Editor.
Allegiant's goal was to keep innovating on the Macintosh product, while delivering a Windows runtime environment (edit on the Mac, run on Windows or Mac) and ultimately a Windows authoring environment. A Windows version was close to being finished, but never made it to a release. The firm also created a SuperCard "Plugin" they called "Roadster" in 1996 to run "projects" — the SuperCard version of stacks — in a web browser. Roadster on the other hand, was released for the Windows platform.
In May 1998, Incwell DMG acquires SuperCard and all related products from Allegiant. Shortly thereafter, version 3.5 is announced. This version, which was finally released in October of 1998, was faster than its predecessors, had support for QuickTime 3, Drag and Drop, AppleEvents, and more.
Version 3.6, released in 1999, brought a Japanese version and many internal improvements.
[edit] The 21st century
In 2002, SuperCard was acquired for the fourth time. This time, Solutions Etcetera, the company that had been developing SuperCard for IncWell, bought the product, and announced version 4. This new version introduced Mac OS X support, complete theme compliance and a wide range of user interface elements to go with it.
Since then, versions up to 4.6 have been released, bringing improvements and bug fixes, as well as support for Apple's new Intel-Chip-Based Macs.
