Easter egg from Macintosh SE ROM — one of four development team photos

What’s old is new again.

Back in the early Macintosh computer days, when the Earth’s crust was still cooling, getting photos and artwork to look presentable on these computers’ 1-bit monochrome displays was something of an art form.

Much of that know-how has fallen by the wayside as screens improved…but with wafer-thin, ultra-low-power 2- and 3-color E-Ink displays appearing everywhere now, a refresher in those techniques is suddenly relevant again.

A couple of software options are shown in this guide. ImageMagick (a free command-line tool) and Photoshop (not free, but many folks already have it).
