This is an MCedit schematic format file (zipped) for the Apple IIe built in Minecraft (updated for 1.12.1), as featured on a blog post elsewhere on this site. Download this and use MCedit to paste it onto your world. (Note: I am not going to describe how the MCedit process for loading schematics works – you will have to learn that elsewhere on the Net).
Also, as a bonus build, I have included my old Skyblock island, recreated in Creative mode from videos and screenshots I took from my old Hatfilms Skyblock account several years ago.
