Closing Remarks
Vendor Fair
Vendors will have an area to set up their stuff, right at the beginning of the event. The vendor fair time is when you can expect that people who have things to sell will be around to sell you their things. (Vendors: space is free, but please sign up for it.) Vendors may be around individually at other times as they see fit and according to their whims, but the vendor fair time slot is when you will most easily be able to transact.

6 Line Programming Contest
- Create an Apple II program in any language.
- The program is limited to 6 lines entered after some standard startup. CALL-151, INT, FP don’t count as lines.
- 2026 Secret ingredient: the program needs to respond to pressing the @ key with some kind of easter egg.
- Deadline: noon on Sunday
Print Shop Custom Graphic Contest
- Draw a Print Shop graphic (standard, monochrome Print Shop format).
- Design a Sign including your new graphic. Other project types (like Greeting Cards and Banners) will be accepted, but remember that the focus of the contest is the graphic.
- Deadline: noon on Sunday. Allow time for printing.
- For a streamlined experience, consider using Total Reprint, released at INIT HELLO 2025.
The Disks We Almost Left Behind: Stories of Apple II Software Preservation (Stephane Racle)
Software preservation is about more than bits and bytes – it’s about people, and the human connections that link us to our fragile digital past. Through photos and personal anecdotes, this presentation explores the detective work and serendipity behind saving our shared Apple II heritage… including a 23-year adventure that continues to this day.
Demonstration of JCM’s new Megaflash for the Apple IIc (David Schmidt)
Demonstration of the Megaflash for the Apple IIc – its capabilities, in-situ disk updates, clock function, etc.
The Prime Plotter: a startup story (Ron Zahavi)
This presentation will introduce the history behind The Prime Plotter, a graphics and statistics software package that was developed by my family startup in the early 80’s. The presentation will include:
- Why the software was developed
- Some innovations (memory management and modules, replay and pen plotter support, copy protection, 3D graphics and pie charts, customizable default parameters, and more)
- Lessons learned and anecdotes (including magazine reviews, vendor agreements, Applefest shows, and meeting Steve Wozniak).
A demo will be given and can continue afterwards at a table.
COPY OF A COPY (Mark Pilgrim)
I set out to fix a 40-year-old bug in Copy II Plus and ended up rebuilding the entire application (and fixing the bug).
Introducing File-Ogeny: a phylogeny tool for digital archivists and software archaeology. (Charles Mangin)
What is “phylogeny?” How is it typically applied? How can it be of help in digital archiving? What bizarre abomination has Charles created this time? And is he accepting suggestions for a better name? (Answer: Yes)
LibreOffice: Import and Export Apple II files (Geoff Weiss)
LibreOffice has an extensible macro and extension support to let users add
support for new functionality. There will be a live demo showing that it
is now possible to import and export Applesoft BASIC files and import
AppleWorksGS Word Processor documents into LibreOffice Writer. It will be
followed by how developers can program support for other Apple II
document types.
Appletini: ALL THE THINGS (John Flanagan)
Watch as we demo the current state of the Appletini prototype. Solid state storage, both hard drive and floppy, including WOZ support. Full Phasor support, 4 AY chips plus SSI voice. USB mouse. Real time clock. Ramworks-compatible expanded memory. Uthernet II. And CPU acceleration up to 22x.
All. The. Things.
Deathmaze 5000, the Fair Play edition. (Sean Gugler)
This 1980 escape room style game is notorious for its unfair puzzles. So I fixed them. Call me a script doctor of puzzle design. I present to you my in-depth analysis of the game’s structure – no code expertise necessary. Warning: spoilers! You may want to play the game before attending, perhaps with some help from my self serve incremental hint system. https://github.com/sean-gugler/DeathmazeFairPlay
Prodentify – a ProDOS identification service. (Sean Gugler)
See what’s changed since last year, when I presented the beginnings of my automated analysis system. You give it a ProDOS system disk or file, and it will tell you whether it matches exactly any known Apple distribution, or else what modifications it has and which Apple distribution it derives from.
