SK8 (pronounced "skate") was a pioneering multimedia authoring environment developed in Apple's Advanced Technology Laboratory from 1988 until 1997. The original motivating idea for SK8 was to realize a development environment that would be easy to learn and that would help people to create applications by simply drawing (visual programming).

SK8 was designed for rapid development of customizable and extensible media authoring tools and titles. SK8 was a proprietary, internal development tool used by Apple designers and engineers--it was not an Apple consumer product. SK8 has been used as a tool to prototype new ideas and products, as well as a testbed for advanced research into authoring tools and their use. The goal of SK8 has been to enable productivity gains for software developers by reducing implementation time, facilitating rapid prototyping, making development fun, and supporting cross platform development and providing output to multiple runtime environments including Java. SK8 was successfully used to create rich media tools and titles simply and quickly.

Before anybody gets too far in using this, SK8 was never finished. At least one Apple engineer had a rather bad time when a developer tried using it like Director or Authorware.

Funny that you link to Jim Spohrer's ATG postmortem doc, Thej. Chris "Apple Employee #8" Espinosa name checks him in one of the replies:

Cam, with this thread you got maybe 500 people interested in SK8, which is a lot more than Jim Spohrer and I ever did

Here's some more info about SK8 and other related projects from the Apple Advanced Technology Group.

The "Purchase" FTP mirror link is also down. I also saw that link listed at the end of Sk8's Wikipedia page.

Both sk8sources.sit.hqx (at and (at are missing.

Edit: In the meantime, this is what I found:
And a magnet link containing sk8 stuff plus some other classic mac software (not sure if it's safe to post it, because I dunno its contents, but you'll easily find it if you google the .sit.hqx file name above).

Edit 2: So, as far as I can tell, the .zip file here in this page actually contains everything related to sk8 already, with there being no further need for the "Purchase" FTP link (now broken anyway). I didn't realize this earlier, until I unpacked the .zip file. I should have done that sooner.
tl;dr: All is good. Smile

You're right (my bad)
for some reason, after unzipping the first file, the .hqx files show up with little Zip icons
but they are sit.hqx and I had NO PROBLEM unstuffing them within Basilisk


And this program looks really interesting (specially the weird splash screen), the GUI looks Professional, I felt like tinkering with it right away, I think there's a big learning curve ahead of me.

Thanks for sharing these rare Apps

The zip file should contain a lot of .hqx files, not a lot of zip files.

I added a "purchase" link here which should take you to an ftp server where you can download the individual files.

Yes, Apple took down the research directory on their ftp server earlier this year....

Wow, this one looks interesting,
specially the description got me hooked.
I'm gonna check it out.


(BTW the link provided to the FTP:// site is broken )

Problem is, I cannot open it, this is a .ZIP file containing a lot of other .ZIP files which
cannot be opened, I get ERRORS.
or maybe this is supposed to be open WITHIN emulation or Real Mac
using MacZip? maybe this is where MacZip becomes useful, I'll try one more time.

This is an archive of what used to be available on . It includes both 68k and PPC versions of SK8, the SK8 source code itself, etc.
