SolderFest is a KansasFest tradition.  Whether you’re a expert at soldering or aren’t sure which end of the iron hold, this evening event is an opportunity to get together, melt metal, swap stories and know-how, build cards, or repair things.

If you own soldering equipment, please bring it.  We’ll have a limited number of loaners, too.

Of course, you’ll need a project to work on, and here are some suggestions:

Vince Briel from Briel Computers and Henry Courbis from ReActiveMicro will be available to answer questions and assist with any issues or assembly questions with kits purchased.

Registration opens for 2018

Posted Fri, Mar. 30th 2018 in News

KansasFest 2018, the 30th annual Apple II convention, is open for registration. Users, programmers, hobbyists, and retrocomputing enthusiasts are invited to Rockhurst University in Kansas City, Missouri, from Tuesday, July 17, through Sunday, July 22, for six days and five nights of sessions, demos, announcements, contests, and camaraderie.

The keynote speaker will be Roger Wagner. In 1978, Wagner started his own software publishing company and sold popular titles such as the Merlin assembler and ASCII Express. He wrote for many major publications of the day but is best remembered for his long-running Assembly Lines column in Softalk, teaching 6502 assembly language. Later, he made his most famous contribution to the 16-bit Apple IIGS with HyperStudio, a foretaste of the hyperlinked web that was to later arrive in the 1990s.

Because KansasFest 2017 sold out, this year’s event capacity has been expanded by 20%. Registering early is still a good idea; do so by May 31 to guarantee a price of $385 for a double room or $455 for a single, which includes admission to all sessions as well as most meals. After that, prices rise. Official KansasFest shirts are extra and optional and must be ordered by June 18; registration for staying on-site closes July 1. To register, please visit the official registration form.

To celebrate this year’s event Steve Weyhrich created a new music video, “The KFest Show”, in his own funny and inimitable style. As the lyrics say, “don’t fight it, registration’s open, runnin’ at ya!” You can watch the video now.

KansasFest invites any and all Apple II users, fans, and friends to attend the largest and longest running annual Apple II conference. For photos, videos, schedules, and presentations from past year’s events or to sign up for the email list and for inquiries, please see the menu at the left side of this site.


Call for Sessions

Posted Sat, Mar. 24th 2018 in News

Event registration will open soon, but there’s no reason why we can’t start talking sessions. While the evenings and nights of KansasFest are renowned for their spontaneity, the mornings and afternoons are reserved for sessions spanning a variety of uses, extensions, and applications of the Apple II family. Just as varied as these sessions are the good people who volunteer to present them. If you have a topic you’d like to present, please fill out the session proposal form.

As introduced a couple of years ago, we’ve reduced the number of after-dinner sessions to free up more evening time for spontaneity. The logistics:

  • Session proposals will be accepted until May 31.
  • After May 31, the KFest committee will review all proposals and select a good number to fill out the schedule.
  • We will then e-mail to let you know if your session is accepted.
  • Fear not, if your session doesn’t make it in this year, we’ll strive to get you in next year.

Past sessions have included hardware, software and game demonstrations, and tutorials; integration of the Apple II with other devices; emulators; programming; Apple II history; or any subject that would be of interest to Apple II users. We also love other retro computers, especially if you incorporate into your session how it compares and contrasts with the Apple II.

Sessions are typically 15, 30, 45 or 60 minutes in length and are held at various times throughout the daytime hours. Keeping your session proposal to 45 minutes or less will let us fit more sessions into the schedule.

If you’ve never done a session, check out a sample of past year’s contributions.

Do you have a topic you would like to see presented, even if you aren’t the one to do it? Email us your idea or post it to the e-mail list and maybe someone will be inspired to step up.

Roger Wagner to deliver keynote

Roger Wagner

KansasFest 2018, the premier annual Apple II convention, is scheduled for July 17 – 22 in Kansas City, Missouri. This year marks the 30th time that this event has been held. In July 1989, Resource Central held the first A2-Central Developer Conference, focused on the individuals and companies who were still producing hardware and software for the Apple II and IIGS computers. Within a couple of years, the event transformed into a conference for Apple II developers and users alike.

This year, KansasFest welcomes back one of its alumni, Roger Wagner. Though 2018 will mark Wagner’s third time as a keynote speaker for the event, most current attendees haven’t had the opportunity to hear him speak because his last appearance was 23 years ago.  He has deep roots in the Apple II community, back to the beginnings of the platform. In 1978, Wagner started his own software publishing company, Southwestern Data Systems (SDS), as a vehicle for some of his first software products for the Apple II, Programmer’s Utility Pack and Apple-Doc, sold on cassette. He also wrote a word processor for the Apple II, The Correspondent. SDS sold software written by other authors, including Glen Bredon’s popular Merlin assembler, The Routine Machine by Peter Meyer (Applesoft extensions), and ASCII Express and Z-Term by Bill Blue, as well as games such as BEZARE by John Beznard and NORAD.  

During the years he also wrote articles for the major publications of the day, including Call-A.P.P.L.E., Nibble, inCider, A+ Magazine, and GS+. Wagner is best remembered for his long-running Assembly Lines column in Softalk, teaching that first generation of Apple II users how to write software in 6502 assembly language.

He later renamed his software company to Roger Wagner Publishing, and continued to provide quality software for both the 8-bit Apple II and the 16-bit Apple IIGS. His most famous contribution to the IIGS was the HyperCard-inspired program, HyperStudio, which linked pictures, audio media, and text with clickable links, a foretaste of the hyperlinked web that was to later arrive in the 1990s. With his original background in teaching, Wagner continued the HyperStudio legacy by later developing it for Windows and Macintosh computers, and focusing on its application in the school environment, to teach students to create presentations and to learn about computers. He further developed HyperDuino, an Arduino-based hardware extension for the HyperStudio to allow students to control real-world devices with their projects.

KansasFest is an annual convention offering Apple II users and retrocomputing enthusiasts the opportunity to engage in beginner and technical sessions, programming contests, an exhibition hall, and camaraderie. KansasFest was originally hosted by Resource Central and has been brought to you by the KFest committee since 1995. Any and all Apple II users, fans, and friends are invited to attend this year’s event. In upcoming weeks, the KansasFest web site will announce registration details. For photos, videos, and presentations from past KansasFests, please browse the “Sessions” and “Multimedia” sections of the site.

Apple II Forever 2017

Posted Fri, Sep. 15th 2017 in News

Since 2010, the KansasFest Committee has recognized members of the Apple II community who have made significant contributions to the Apple II, either in promoting or developing for the platform during its active years, or in helping to advance or preserve the Apple II since its production had been discontinued.

This year, we recognized three individuals:

Plamen Vasilov of A2Heaven delivers innovative and useful hardware for the Apple II, including battery-backed memory cards, VGA video adapters, a floppy drive emulator, and sound cards.  Most recently, he introduced a 16.6 MHz accelerator for the Apple IIe.  He uses modern components to deliver products that are smaller, are lower-power, are lower cost, and have more features than previously available, and he is both advancing and preserving our favorite computers.

Glenn Jones with A2 Retro Systems connects our Apple IIs to modern computer networks and the Internet with the Uthernet expansion card.  He released the latest generation of this card, the Uthernet II, in 2015.  Besides facilitating file transfer and preservation, his work enables new telecommunication applications for the Apple II, such as Web browsers, e-mail clients, Web servers, and chat clients.  The potential of Glenn’s work is not yet fully realized, and he is helping to advance what’s possible with our machines.

Quinn Dunki embodies the hacker spirit that founded the Apple II.  She designed and built her own 6502-based computer, Veronica.  She has disassembled and improved the Apple IIc Plus ROM and has prototyped an Apple IIc with integrated monitor and mass storage.  She has contributed original software libraries for Apple II sprite, mouse, and GUI programming, and she created a tool that greatly simplifies 8-bit assembly programming.  Most significantly, Quinn inspires others through freely sharing her knowledge and expertise.

HackFest 2017

Posted Fri, Aug. 25th 2017 in News

You might think that software created in a few sleepless distracted days wouldn’t be amazing and noteworthy.  And, you would be wrong.  This year’s HackFest entries show incredible skill and creativity.

The entries include:

  • Martin Haye: Invoking Apple III Satan Mode, an assumed-to-be-impossible way to access Apple III hardware from Apple II programs.
  • Ivan Hogan: An assembly language game making use of the text screen. Jump on the lines without touching the heads!
  • Jeremy Rand: ColourGo, an implementation of the casual game Chameleon Run, using Apple Hi-Res.
  • Russ Ross: An implementation of the classic casual game 2048, using the text screen.
  • Rob McMullen: Fujirun, an assembly language game based on Amidar. Save the Apple from the Atari interlopers!
  • Alain Zanchetta: Hacking Sargon II to take input not from the keyboard, but from another copy of Sargon II connected by serial port.
  • Alex French: Rendering particles on the Apple IIgs in Super Hi-Res, while playing nice with GS/OS.
  • Charles Mangin: You Are a Grue – A text adventure written in Inform 7.
  • Kevin Savetz: A version of the Simon game, with custom-made button controllers hacked on-site to interface with the joystick port.

The winners were:

  1. Rob McMullen: Winner for sheer scope, the level of polish, and the embracing of modern community tools.
  2. Charles Mangin: Winner for stretching outside his comfort zone, creating something clever, and refusing to give up when his first idea failed.
  3. Alain Zanchetta: Winner for the creativity of his idea, and embodying a true hacker grit in the project.

Many entries, often with source code, are available here.
