Apple is taking pre-orders today for the Apple Watch, and they're showing it off in select stores. This is great news for anyone who wants cutting edge 21st century wearable tech, but those of us who value the sleek design of the early 1980s are holding out for the Apple II Watch.
The Apple II Watch features a 3D-printed shell, and runs on an incredibly fast (by the standards of the 1980s) 72MHz Teensy 3.1 SOC. It packs in a 1.8" LCD screen, a tiny speaker, and an 800mAh battery. Input is limited to just a single rotary knob (no touchscreens here), but to complete the period look and feel Aleator777 also added a couple disk drives. They're nonfunctional, which is a shame because that would be a great place to add a couple microSD cards slots.
The Apple II Watch runs Arduino software, but without connectivity or a touchscreen there's not much that you can do with it. There's a boot animation (complete with period authentic sound effects) and you can use the knob to scroll through a menu, but the submenu options are really just screen images.
I'm okay with that. As we all know, the second iteration of any Apple product is the one where they get it right.
That means that we should probably hold out the next Apple II Watch before investing, but if you don't want to wait then you should head over to Instructables. Aleator777 has posted a set of instructions for building the Apple II Watch, including the schematics for printing the shell.
