Another World On The Apple II

What’s more fun than porting an old game released for an old system such as the Apple IIgs to its 10-year-older predecessor, the Apple II from 1977? Cue [Deater]’s port of the classic video game ‘Another World‘ to the original Apple II. As was fairly obvious from the onset, the …read more

Reverse Engineering An Ancient SBC With An Apple ][

We spend a lot of time in our community discussing the many home computers from the 8-bit era, while almost completely ignoring their industrial equivalents. While today a designer of a machine is more likely than not to reach for a microcontroller, four decades ago they would have used a …read more

Bit Preserve: A Sanctuary For Modern Captures Of Vintage Schematics

Vintage parts may be documented, but that doesn’t mean they’re particularly useful or accessible. If the phrase “eyestrain from unsearchable, badly-scanned PDF datasheets” makes your lower eyelid twitch in sympathy, read on.

While [Bald Engineer] was researching how he might make a portable Apple II, he was delighted to find …read more

Travelling The Oregon Trail With An Apple II Robot

For one reason or another, we’re going with a retro-futuristic 80s aesthetic in this case, [Mike] decided to turn an Apple IIe into a robot. If you have to ask why, you’ll never know, but this project does have some interesting things going for it. There’s a voice synthesizer, a brand spankin’ new power supply, and it rolls around on the floor thanks to Apple BASIC.

Since this is a mobile robot, there needs to be a power supply in there somewhere. The Apple II had a fantastic switching power supply, but it ran off mains voltage. To make this …read more

Apple II Megademo Is Countin’ Cycles and Takin’ Names

The demoscene is an active place to this day, with enthusiasts around the world continuing to push the envelope as far as the capabilities of machines are concerned. [Deater], along with a skilled team, produced this Apple II Megademo which won first place at Demosplash 2018.

The demo starts with an intentional tease, with an emulated C64 BASIC startup screen which splits to reveal the title card. White-on-blue text isn’t the easiest on the Apple II, due to palette limitations, but it’s necessary for the joke to work. The following scenes make heavy use of mode-switching techniques in the middle …read more

Re-enacting TRON on the Apple IIgs

TRON is a science fiction classic, hitting cinemas in the midst of the burgeoning home computer era. It’s the film that created the famous light cycle, which spawned many video game recreations in the following years. Many years ago now, [Daniel] decided to flex his programming muscles by coding a version of the game for the Apple IIgs, with accidentally excellent results.

In the film, the characters find an escape from the light cycle game by forcing another player to crash into the walls of the play area. The resulting explosion left a hole, allowing the players to exit the …read more
