SlipKnot Wins Shareware Award

On June 23, 1995, Ziff-Davis/PC Magazine announced the winners of its annual Shareware Competition. Over 1,300 entries were submitted, "judged for innovativeness, quality and value", and subsequently divided into 16 functional categories.
For reviews, testimonials and other commentary on SlipKnot, please see our SlipKnot Reviews Page.

Also, our Who Needs SlipKnot? page offers some comparisons with the traditional SLIP/PPP approach to the Web.

Features (as of version 1.40)

  1. Does not require SLIP or PPP or TCP/IP in any form -- it makes use of an ordinary dial-up UNIX shell session. Does not use TIA or remsock, and places no executable binaries on the UNIX system.

  2. Allows you to switch between SlipKnot's Web browser and its UNIX terminal window at any time (except when documents are being retrieved). The terminal window allows:

  3. Can save entire documents -- including the embedded pictures -- in your own local directories. These documents can be redisplayed at any later time, including offline. This allows you to demonstrate the WWW even when not connected to it, since the document links to each other are saved with the documents.

  4. Documents are retrieved in the background, allowing you to scroll through other displayed documents or print, etc. during retrieval.

  5. Displays up to 10 documents on the screen (user choice between 2 - 10).

  6. "Get All Links": SlipKnot can be told to retrieve all or some of the links inside any particular document and allows you to choose those links you wish to retrieve ahead of time -- no other browser we know of has this feature. (Feature restricted to registered SlipKnot users).

  7. The text of the documents will be displayed first.

  8. Document windows can be resized.

  9. Displays most graphics formats, and will play sound files (if you have sound capabilities)

  10. Documents are saved with your comments attached, to make them easier to find later.

  11. Screen fonts and printer fonts are changeable.

  12. Keeps an unlimited session cache (limited by available disk space) of retrieved documents.

  13. You can ask for more than one document while waiting -- requests are automatically queued up.

  14. Since SlipKnot is also an offline document renderer, so you can use it to display your own home pages while they're in development.

  15. SlipKnot will retrieve files via anonymous FTP for you.

  16. SlipKnot will run Gopher for you, although access to this feature is limited to registered users.

  17. SlipKnot will send outgoing mail (supports "mailto:" HTML tag).

  18. Last, but definitely not least: SlipKnot has built-in upgrading capabilities (see below). When new versions are released, SlipKnot users can click on a built-in SlipKnot link, which will retrieve and upgrade the product itself.

Design Note: SlipKnot was specifically designed for modem and serial line users. Unlike many other World Wide Web browsers, SlipKnot understands that its users will have to wait a while for each document to be retrieved from the internet, no matter which browser they are using. Therefore, we included many features to allow multiple documents to be seen, stored, and printed so you don't have to retrieve documents unnecessarily, and so retrieval can be performed in the background.

Upgrading SlipKnot

We are committed to improving SlipKnot, and have designed the software to make it very easy to upgrade with its One-Touch Upgrade feature. Since SlipKnot was released in late November, 1994, we have released numerous upgrades, each with additional features and bug fixes.

Since SlipKnot is an Internet communications program, it has built-in code to upgrade itself. Here's how it works:

  1. The SlipKnot Local Home Page (part of SlipKnot) appears every time you get into the Web. There is a built-in link on this page to our "What's New Page" on the Internet.
  2. The What's New Page announces the latest released upgrade for SlipKnot. If the new version is more recent than the one you are using, you can get the upgrade file (for free until version 1.99) -- there is a link in this What's New Page to retrieve the SlipKnot upgrade file. This upgrade file is much smaller than the full distribution file (containing only changes).
  3. SlipKnot has a built-in upgrade program that will take the changes file and apply them to your version.
The entire upgrade process can be accomplished with about 7 button clicks and normally takes 3-15 minutes (depending upon modem speed).

The SlipKnot What's New Page also contains announcements of interest to SlipKnot users and the status of the product.

Limitations (truth in advertising)

System requirements

PC System requirements:

  1. Microsoft Windows (tm) 3.1+ running in 386 Enhanced mode, or Windows for Workgroups, Windows NT, Windows 95, or OS/2-Win.

  2. We believe that SlipKnot will run with the new SoftWindows 2.0 emulator for the Mac.

  3. A UNIX dial-up account (with or without modem) with shell access (or BBS or Freenet -- see below under UNIX requirements). You must have write permission to your UNIX home directory. Shell access is required -- SlipKnot will not work with UNIX systems that trap you inside of menus.

  4. At least 4 MB of RAM memory; recommended 8 MB. Since SlipKnot is a graphics program, the more memory you have, the better.

  5. At least 2 MB of available hard disk space. SlipKnot itself takes approx. 1.5 MB, but since it allows you to save your documents, more free space is much better.

Requirements of your UNIX system:

The UNIX system must:

or, if it is a BBS or Freenet:

Note to UNIX service providers:

SlipKnot does not deposit any executable binaries on your host. It makes use of only the following UNIX commands: "ls", "echo", "rm", "chmod", either "lynx" or "www", and whichever programs you offer for X, Y or Zmodem or Kermit file transfers.

Because SlipKnot is able to save entire documents (including the embedded pictures) on the user's local PC, your users do not have to retrieve any document more than once.

Note from Peter Brooks, President of MicroMind and developer of SlipKnot:

SlipKnot was created because there was, at that time, no other alternative to accessing the World Wide Web graphically if you did not have SLIP or PPP or TCP/IP access. Having analyzed Mosaic and some of its competitors, I concluded that all of these browsers were designed for people with very rapid communications channels into the Internet, not modem or serial line users. Even if you have SLIP access, many of these browsers do not allow you to save entire documents (with the included pictures), forcing you to retrieve the documents again whenever you wish to take a full look at them -- eliminating the possibility of demonstrating WWW without being online. It takes a while to retrieve any document by modem with any browser, and you shouldn't have to do this more than once.

The Web is a remarkable human construct and a truly a wondrous place. I hope that SlipKnot brings you the magic of the Web, and that you become as astounded by it as I am.

In addition, since SlipKnot was released in late November, 1994, we have received thousands of messages from thankful users. Some of these messages can be seen in SlipKnot Reviews. We would, in turn, like to thank all of those folks who have sent us their suggestions, concerns, bug reports, and words of encouragement.
