Before he co-created the legendary Mac game Dark Castle -- long before he led development on the now-dominant Flash multimedia platform -- Jonathan Gay made a little black-and-white game called Airborne. The Macintosh was still in its infancy at this point, and Airborne was released more-or-less alongside the freeware Banzai!, but this did little to detract from Airborne's appeal.

The concept is simple: destroy the advancing tanks, planes, helicopters, and soldiers with your mortar or anti-aircraft gun before they reach your position. If someone gets close enough to shoot you, you lose -- presumably ending an admirable, or perhaps foolish, last stand against all odds to repel an invasion force. If you manage to defeat them all, a new wave arrives. There is no winning, just a staving off of the inevitable and a hope of setting a new high score.

Mac OS X turns ten this week. That's ten years since the first public release of the jewel in the crown that signifies Apple's rise from the brink of death with a modern and "revolutionary" clean slate. But it wasn't the first time a piece of Apple software saved the company -- that honour goes to the original Macintosh operating system: System 1.0. Read on to learn how Apple changed its fortunes and revolutionised computing back when the terms GUI and mouse were foreign concepts.

The core of the Macintosh experience was never the attractive industrial design, the sense of superiority, or the use of a strange one-button mouse -- although those elements were vitally important. From the very beginning, even before the first Mac hit the market in 1984, right through to the latest iMac or Macbook models, the Macintosh was about providing the most accessible and intuitive interaction possible between humans and computers.

Computers should be easy to use, with user interfaces that Jack and Jill Smith who just walked in off the street can use comfortably with almost no instruction. Gestures, not typed commands; desktops, buttons, and icons -- not command lines, carriage returns, and terminals -- have clear analogies to things from everyday life that people without a degree in computer science can understand. This is at the heart of the Apple philosophy, as it has existed since that fateful trip to the Xerox labs in December 1979.

Editor's note: Radical Castle is one of the earliest graphical adventure games, and is a key component in the point-and-click revolution ushered in by the Macintosh in the mid-to-late 80s. If you have any interest in adventure games, you should play this. -mossy_11

Radical Castle is a 1986 World Builder adventure classic designed by Christopher Kent Wigginton, which was originally distributed as shareware on multiple cover disks. I first came across Radical Castle around 1988. As a kid I would wait around in mumʼs office fiddling with her Mac Plus. The office had an intranet that I used to search for shareware/freeware apps. When mum returned to her office she was often surprised to see little gadgets on her computer, such as eyes that followed the mouse and Oscar the Grouch in the trash. Radical Castle fit in well with these gadgets.

You play the role of a squire who has fallen out with the king over a secret meeting you had with the princess. Although you are repentant and honestly thought that the princess was a serving wench, the king still isnʼt happy. He gives you a choice between death and a long quest to find an oracle that an evil wizard has stolen.

When Windows 95 came out, I didn’t care. Sure, I was just a kid, but I could clearly see that it was inferior to System 7.5.5. Years later I learned this isn’t strictly true -- although the feature gap was almost non-existent (despite what Windows’ marketing suggested), they each possessed different strengths and weaknesses. But all I saw was an ugly interface, a continued reliance on the dated DOS back-end, and the infamous blue screen of death. And games still looked better on the Mac, even with the aging hardware.

It was like a window to another dimension, where somehow everything bad reigned supreme over all that is good. I didn’t like it. I wanted to close the shutters and pretend there was no other dimension. But there was no escaping Windows, and I soon came to terms with my aversion for the OS, thanks in large part to a game called Civilization II and a little thing called the Internet.
