KansasFest 2015 Thursday Report

Thursday’s report is brought to you by fifth year attendee Mark LaPlante

Thursday (Day 2)

Today’s schedule was packed full of mostly technical sessions. Some were about software, some were about hardware, some a little of both, but what struck me most, and what I enjoy about KFest, is they were about collaboration.

Following breakfast Stephen Buggie explained the importance of EPROMs, creating them, preserving them, and sharing them with others. At least according to the session guide. I am not a morning person and, unfortunately, I missed both breakfast and that talk. My apologies.

Next, Quinn Dunki delved into the basics of mouse programming on 8-bit Apple IIs, a much more complex topic than I had imagined owing to the fact that different design approaches were taken on different machines. Quinn has generously provided a generic mouse driver and sample code at https://github.com/blondie7575/MouseII. During her talk she mentioned how her driver could not detect multiple mouse clicks between mouse movements. By this afternoon, she and Rebecca Heineman had teamed up to squash that bug!

Later in the day Charles Mangin of RetroConnector addressed the many versions of pre-ADB Apple II and Macintosh mouse hardware. Audience members speculated that a lack of collaboration between the Apple II and Macintosh teams (perhaps involuntary) may have led to early mice not always being compatible with both. Charles announced and demonstrated new products (pricing TBD) that will allow the mechanical mechanism to be replaced with an optical one (particularly useful if you have a broken or incomplete mouse), or going the other direction, allow a working Apple serial mouse to be used as a USB mouse.

Before lunch, Jay Graham taught us the history of Pascal, how it differs from AppleSoft, and gave a summary of several Pascal compilers for the Apple II. I am most interested in trying Kyan Pascal and it’s Unix-like shell, Kix. Surprisingly, even though he discussed using Turbo Pascal via a Z80 card, he did not go into Pascal for ARM processors installed in Apple IIs. Perhaps someone will take on that challenge next year.

After lunch, Javier Rivera showed us his techniques for converting CRT monitors to use LCDs. This often takes many months of research into finding panels of a suitable size. Results with LCDs are discussed pretty regularly on the Apple II Enthusiasts Facebook group, so keep an eye out there and share your results as well. You may learn of non-obvious solutions like Javier’s discovery of a visor-mounted display intended for use with a rearward-facing camera system for large trucks as a retrofit for the Apple IIc Flat Panel Display, finally making it usable, and in beautiful color.

Jason Scott entertained us with stories of at least five ways he and teammates at the Internet Archive have brought the Apple II into public view this past year. The Internet Archive web site has had a facelift and there are hundreds of Apple II software titles able to be run in a web browser. He and his request to be sent any and all CD-ROMs were featured on NPR and he has thanked them by outfitting their studio with an Apple II and three issues of Compute! magazine so they can experience the exhilaration of typing in programs.

Mark Pilgrim showed us a clever copy protection method involving intentionally getting the reading of data out of sync. This slowed down pirates over about 6 years as more and more publishers gradually adopted the technique. Rebecca Heineman pointed out that this had a side effect of making many very popular programs crackable all in pretty much the same way once a technique was discovered.

After dinner, Martin Haye spoke on behalf of the Lawless Legends team about their progress over the last year. Ivan Hogan has produced an amazing new font engine, David Schmenk’s PLASMA language has been enhanced and incorporated into much of the game code (PLASMA will be a topic of a session Friday evening), and the team has been working on fleshing out the game scenario. Lawless Legends is a labor of love for its creators, so when asked when it will be done the answer is simple — it will be done when it is ready. Martin is taking the request for an updated playable demo to be released back to the team. It seemed like that was a definite possibility; a good place to watch for news is their Facebook page.

Word has gotten out that Kansasfest is a friendly place for fans of other vintage computing platforms, and Kevin Savetz, Wade Ripkowski, and Rob McMullen compared the development of the Atari 8-bit computers with that of the Apple II. It seems there was quite a bit of collaboration between the two companies — well, at least some Atari engineers were working on the Apple II on the side — some contributed expertise, some likely contributed Atari hardware, and some outright left Atari to work for Apple. Kevin laid down a sort of gauntlet by showing an impressive game written in just 10 lines of BASIC — one contest at an Atari conference I won’t even pretend to remember the name of.

There were several parallel workshops in the evening. Some people worked on Briel Computers kits and Chris Torrence led folks through building a cable which allows feeding a Night Owl security monitor with video and power from a IIc monitor port. KFest is crawling with this monitor this year — a buying frenzy ensued a while ago after it was discussed on Facebook. Others helped repair keyboards, install oscillators and EPROMs, troubleshoot game controllers (a Flapple Bird and Lit’l Red Bug game tournament was taking place in an adjacent conference room). The smell of solder, flux, and Krispy Kreme donuts wafted throughout the building, and life was good.

Finally, I would like to discuss the session that brought the theme of collaboration to mind the most for me. Dagen Brock shared all the ways he has worked with Apple II enthusiasts from all around the world throughout the past year. Following an impromptu Programmer’s Roundtable at last year’s KFest, Dagen was inspired to register and create a web site dedicated to Apple IIGS programming at www.apple2.gs. He collected and linked to a library of IIGS reference books, created a series of YouTube videos, published demos old and new, presented remotely to OzKFest, and disassembled and enhanced Transwarp GS firmware. I am sure I have left something out, but it was the disassembly project that really drove home the importance of collaboration. After disassembling most of the binary with The Flaming Bird disassembler (including translating 30+ pages of documentation from French to English), Dagen got stuck and turned to the Facebook group for help. It was only then that he learned that Antoine Vignau had already disassembled the firmware a few years ago.

So, folks, when you can, share early and share often — you never know what someone else may be working on. There are many rewards to be had when playing with our favorite computer, and, I like to think, even more so when we are able to cooperate across geographical and cultural boundaries.

Dagen Brock introduces Crusty Coders site for Apple IIGS programmers

This is a place to learn about programming the Apple IIgs.

This came about as a result of a conversation with fellow Apple developers who, like myself, found a lack of centralized resources for Apple IIgs specific documentation. This is just an early design and a place to start putting the information together. The goal is to add the ability for user contributed content via a wiki, forums and other collaboration tools. For now, it’s really just beginning, but I hope you enjoy it and if you’d like to help out, let me know via the contact page (once I make one).

You can find it at Crusty-Coders.com (currently resolving to apple2.gs).

Alex Lee on IIGS System Extensions

Alex Lee (What Is the Apple IIGS) has published a definitive collection of Apple IIGS system extensions and is sharing his advice and opinions on many of them. System extensions can expand the usefulness of your IIGS, or they can slow down your machine — even to the point of making it less stable. Sometimes, it can feel like there’s a little bit of voo-doo involved.

Help request: advice for an unreliable SCSI drive

Ken Gates needs help with his cranky SCSI drive.

Hi, I still use my Apple IIe with a Q-Drive hard disk. I run AppleWorks and keep a super large list of movies on the drive, as I’m a movie buff. I’ve recently been having hangup on the hard drive. I’ve been trying to troubleshoot it and/or use some of my old programs to test it, but so far I’ve had no luck in locating the problem. Is there any program that I could use to lock out bad sectors? Any advice you can give will be greatly appreciated. I assume that no one makes a hard drive that I could use with my IIe! I’m running a SCSI card out of slot 7 to the Q-Drive.

Ken, the first thing I recommend is to verify you have a good backup! If you don’t, backup what you can… and if you are experiencing data loss, you might take a look at the late Glen Bredon’s ProSel Utilities (now freeware) and see if you can recover anything. ProSel 8 (for 8-bit Apples) is available HERE courtesy of Apple2.info.

As for a hard drive replacement, several options exist — take a look at the various compact flash drives available from 16 Sector (Focus $99), R&D Automation (CFFA – sold out, check eBay) and ReactiveMicro (MicroDrive $135). A CF card hard drive is probably the most versatile storage solution for the Apple II.

If anyone else has additional advice for Ken, please post a comment here or write him at: kengates at comcast dot com — semi-obfuscated, so we don’t send the spambots Ken’s way.

Brian Mika needs assistance getting high quality copies of various Sierra Interactive disks for the Apple II.

I am a long-time fan of Sierra’s Adventure Game Interpreter (AGI) games of the 1980’s. I need to get in touch with people who have, or can make, 100% authentic disk copies and graphics/sound samples for use in a research project to decode the Apple versions of AGI games and thus develop superior editors and emulators. Can you help?

If anyone can help Brian out, you can reach him at: bmikaus at yahoo dot com — semi-obfuscated, so we don’t send the spambots Brian’s way.
