Promo put together by WIRED Italia shows a history of modern technology, with a file created on an early Apple gets transferred from machine to machine:
Innovation is not technology but culture. Something able to travel through time thanks to the enthusiasm and passion of people. Here’s the story of an information flow in its switching between different machines, different formats and file-extensions, different communication protocols and over almost 30 years of technology, from the ZXSpectrum of 1982 to the 3D printers of today.
This is how it works. A Macintosh SE/30 displays a file on its screen and saves it as WIRED.TXT on a floppy disk. The floppy is read using a serial peripheral device connected to an IBM Thinkpad. Changing the file-extension from .txt to .jpg, you are seeing the text for what it was originally: a barcode image, which you can open and display with dPaint. The barcode is interpreted by an app that uses a smartphone camera. It’s an http address. The address is copied and sent via SMS to an old Nokia5410i. This Nokia model was among the first to send emails, so it can transfer the SMS text to the email client of an iPad. The iPad activates the address which was written in the email. It’s a .htm page containing a link to a downloadable file: WIRED.WAV.
The file is played and connected with a mini jack to the audio port of a ZXSpectrum. The Spectrum detects it as a .TAP file, a faithful reproduction of audio cassette format which Spectrum used to play and save contents. The programme inside the WIRED.TAP file is a slideshow loading a single image: a QRcode. The QRcode is photographed using a small digital camera. The photo, stored in the SDCard, is read from a laptop and loaded into an album on Wired Facebook account. An eBook page appears in the browser mode. The eBook is scanned, the QRcode image is cropped and then printed on special paper for heat transfer and then ironed on a T-shirt. T-shirt is photographed with an iPhone that reads QRcode for the url it contains. The iPhone sends the address to a laptop: it’s a page containing the WIRED.STL file. The laptop uses this file to produce the Wired logo with a RepRap 3D printer. That’s it. Easy, right?
