Negotiating deals at KansasFest

It's Cyber Monday, and Juiced.GS is selling Sophistication & Simplicity, Dr. Steve Weyhrich's definitive history of the Apple II. I sang this book's praises upon its December 2013 release, even going so far as to shoot an unboxing video:

What brought this book to the Juiced.GS store five years later is a random confluence of events. This past summer marked my 21st time attending KansasFest, the annual Apple II expo held in Kansas City. But for the first time in over a decade, my traditional roommate of Andy Molloy was not in attendance. I asked Steve Weyhrich if I could crash in his dorm room instead.

It was during one evening of cohabitation that my roommate and I got to chatting, the conversation wandering among all aspects of the Apple II community. What I discovered that evening was that not only had Steve received a few complimentary copies of his book, as every author is owed; he also had several dozen extra copies in storage.

If this had come to light 4–5 years ago, I would not have been in a position to do anything about it. But in the last three years, Juiced.GS has become a publisher and reseller for other Apple II entities, such as The Byte Works and Kelvin Sherlock. When I asked Steve if he'd be interested in being the third person to engage in such a collaboration by allowing Juiced.GS to distribute his book, he happily agreed.

What followed were months of emails between Steve, me, publisher Variant Press, the Juiced.GS staff, and other parties. The result was our ability to bring autographed copies of this book to Juiced.GS customers at an all-time low price — all because Steve and I were KansasFest roommates.

The Apple II community at large has long benefitted from the fruits of KansasFest, with collaborative products such as Marinetti having been born there. I'm delighted that Steve and I are the latest instrument of such happenstance.

A modem handshake visualized

If you're reading this blog, you remember this sound:

Whether your Apple II was dialing into CompuServe, GEnie, Delphi, or a BBS, the sound of two modems connecting heralded something magical: an entry into a world, or a part of the world, where you might find faces and files new and familiar. For many, this cacophonous screech welcomed us to a place we could relax, abandon pretenses, and be ourselves — or whatever version of ourselves we wished to present that day.

The lingo of that connection is nearly lost to me now: 8N1 vs. 7E1, RTS / CTS, full duplex. But almost all of it is represented in that same dial-up soundtrack. Not just an unfortunate and inadvertent consequence of data being modulated and demodulated, the sound of dialup embodies the phases of negotiation before two modems can settle into a digital rapport.

These stages can now be visualized in "The Sound of the Dialup Explained",a 42-megapixel poster crafted by Helsinki's Oona Räisänen. Detailing one point in the poster, she writes on her blog:

[The modems] put their data through a special scrambling formula before transmission to make its power distribution more even and to make sure there are no patterns that are suboptimal for transfer. They listen to each other sending a series of binary 1's and adjust their equalizers to optimally shape the incoming signal. Soon after this, the modem speaker will go silent and data can be put through the connection.

I can almost hear it.

The poster is available from Redbubble in three sizes, from two to four feet wide.

We may not often hear these sounds anymore — but we can always have this poster to remind us of that raucous gauntlet we'd once endure as passageway into cyberspace.

Apple II in flight

Once upon a time, before airlines had Wi-Fi, commercial flights were a disconnected oasis where passengers could not be reached by the outside world. It was the perfect time to put away the laptops and catch up on books, magazines, or even handheld games.

Now our computers are with us on every flight — a trend begun in 1983 by Jack McCornack, who put an Apple II on his ultralight aircraft.

"No brakes, no license, no parachute… What is there in this barebones aircraft to hang on to for even the least sense of security? It was designed with the help of an Apple II," writes Melissa Milich in Softalk Volume 3, Issue 5 (Jan 1983).

Jack McCornack of Pterodactyl in flight

Most of the article details how McCornack uses VisiCalc and Apple Writer to run his aviation company, much like any entrepreneur or businessperson might. But on page 125 is a sidebar in which Milich dives into the details of the above photo:

That's an Apple II Plus, monitor, disk drive, and Apple Juice power supply bolted to a wooden mount with foot-long bolts and protective pads. On the two-seater Pterodactyl pictured, the Apple sits where the passenger normally would. The control stick for the canard and winglets is managed with the right hand while the pilot reaches over with the left hand to type on the keyboard.

This sidebar is a fascinating look at the early integration between aviation and digital technology — not only to provide data that pilots and on-ground personnel can use to make decisions, but to actually control the flight mechanics themselves:

In a normal plane, ailerons are controlled by the stick and the rudders are controlled by foot pedals… McCornack is working toward a version of the two-seater in which you can control ailerons with a joystick hooked to the Apple. The computer would control servo motors that activate the ailerons.

Going for a theme, this same issue of Softalk has a similar article on pages 48–54: David Hunter's piece "Exec SubLogic: On Course and Flying High". It's a meandering piece about Bruce Artwick and Stu Moment, two other entrepreneurs who developed the early flight simulator A2-FS1 Flight Simulator (and, later, Night Mission Pinball).

SubLogic had many other innovations in development. Decades before Steel Battalion, they envisioned more complex interaction and input devices:

Not just another joystick, this multiplexed, seven-channel contraption will give a more realistic aspect to the flight simulator, possibly including foot pedals, a steering wheel, a separate throttle, and other features.

Softalk was a great magazine, and this issue in particular was a fun look at the Apple II in flight.

Apple II at the Apple Store Genius Bar

A once-annual tradition of KansasFest was an outing to the Apple Store. Whether it was to Country Club Plaza location, where I was tricked into buying my first iPod, or to the newly opened Leawood location, where the store manager gave us all free t-shirts, it was always fun to check out the latest Apple gear and to set all the in-store iMac's browsers to A2Central.com.

I often fantasized what the reaction would be if it weren't just Apple II convention-goers who arrived at the store, but the Apple II itself. Let's bring our ancient Apple computers and see if it'd be recognized by the even younger store employees. Better yet, let's schedule a Genius Bar appointment to get help installing GS/OS!

I'm not the only one to daydream this scenario: Bryan Villados, Forrest Hodges, and Steve Chamberlin have proposed the same gag. But it was Luke Hsu who finally pulled it off when the first Apple Store opened in Taiwan.

Luke didn't mention any interaction with or reaction from Apple Store employees, though. But we may have a hook to try staging this scene again soon: Apple will be implementing a "Repair Vintage Apple Products Pilot". The program will service products dating back to 2011 only, but the trial is deemed successful, perhaps we can expect that window to reach even further back in Apple's history — and thus, with the Apple II being fully expected and supported at the Genius Bar, the gag will be entirely ruined.
