A timeline of monitors and displays

There are as many ways to connect an Apple II to a display as there have been display types across the decades. Each machine had its own protocols, standards, and benefits. Although the Apple II was designed for color — hence the six-color Apple logo — most people remember a monochromatic experience, due to the black-and-green monitors to which many early computers were connected. The first laptop Macintosh I ever used had a black-and-white display, which was great for playing Crystal Quest but not much else.

A new interactive infographic, "The Evolution of Computer Screens", attempts to chronicle the different ways computers have visually presented data to us over the eras, inviting us: "Take a trip through time and experience the most noteworthy achievements in computer screens, from little known discoveries way back in 1968, to the heated battles between Apple and PC and beyond."

Naturally, such a timeline would be remiss to overlook the Apple II:

There are a couple problems with this artistic rendition, though. First, that looks like a mockup, not an actual screenshot, of VisiCalc — the font just seems odd to me. Second, the accompanying text offers the prompt A>dir, which would never be valid on an Apple II unless it had a PC Transporter running MS-DOS, or a Microsoft Z-80 SoftCard running CP/M — a more representative prompt would've been ProDOS or DOS 3.3's native ]CATALOG. Third, the text doesn't actually say anything about the monitor or the display — there's no explanation justifying the Apple II's inclusion on this timeline.

This timeline is produced by AT&T with no individual bylines attached to it. I don't believe corporate sponsorship of a product is inherently suspicious, but not knowing the pedigree of the creators leaves me wondering what their familiarity with or interest in the topic was.

Fortunately, the timeline includes citations to resources referenced during their research. One such link is to Benj Edwards' 2010 feature for PCWorld, "A Brief History of Computer Displays". As a slideshow, it may lack the pizazz of the above timeline, but Edwards' content is, as always, top-notch. Spanning 1951–2010, the twenty slides cover a range of technologies and applications, including both the Apple-1 and Apple II, with technical explanations for what made each innovation a milestone.

Any acknowledgement of the Apple II in mainstream media is one I appreciate; early Apple's flagship product is otherwise too often overlooked. But clarity of audience, intention, and detail do the Apple II justice and ensure that the reference will be understood and appreciated by those familiar with the topic.
