The Library of Congress and HyperCard #VintageComputing #DigitalPreservation @librarycongress

Jacob Kowall and Hilary Szu Yin Shiue have been working at the US Library of Congress updating and expanding the Sustainability of Digital Formats website, which provides information and analysis on over 500 digital file formats and offers guidance on the long-term preservation of digital content at the Library.

Our preliminary research on HyperCard revealed that the software was a widely popular application in the 1980s and 1990s. In fact, HyperCard is an important piece of Library of Congress history. The American Memory project, an early collection of digitized LC materials, was first built with HyperCard in the pre-Internet era…

Despite its widespread usage in the 1980s and 1990s, HyperCard remains largely absent from the leading file format registries. For example, PRONOM, the UK National Archives’ comprehensive registry of digital file formats, has no entries for HyperCard formats, nor are any included in the Internet Assigned Numbers Authority (IANA) media type list.

The Siegfried file format identification tool also fails to identify HyperCard files, indicating that none of the major format registries include entries for HyperCard. Although Wikidata has a record for the HyperCard file format (Q27996244), it provides little information useful for format analysis. For all the above reasons, we determined that both the Manuscript Division and the wider digital preservation community might especially benefit from further research and aggregated documentation on HyperCard files. Thus began our adventure into exploring the history and resurgence of HyperCard.

When developing HyperCard in the 1980s, its designer, Bill Atkinson, wanted to create a tool that both programmers and non-programmers could use to write their own computer applications. After its release in 1987, Atkinson likened the new program to an “erector set” for software, alluding to the popular toy construction set. Users of HyperCard created documents called “stacks,” which were made up of a series of related “cards.” Each card in a stack could contain text, images, interactive elements, and sound. HyperCard featured a classic, black-and-white user-interface. Despite its relatively humble appearance, the potential uses of HyperCard were extensive.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
