It’s often said that the computers we carry in our pockets today were once the size of entire rooms. They’re talking about this beast. #ComputerHistory #IBM #TechHistory

This computer is the reason you can't download all software for free. The Franklin Computer Corp was a computer manufacturer founded in the early 1980s. Their flagship product was a clone of the Apple II, one of the most popular personal computers of the day. But Franklin didn't just make a machine similar to Apple's: they openly and directly copied the Apple II's ROM, which meant it ran all the same software perfectly. They could do this because it wasn't yet clear if you could copyright compiled binaries. After all, a binary is just a bunch of 1s and 0s, basically math, and you can't copyright math! (Source code was already established as being copyrightable.) Unsurprisingly, Apple sued, and the Third Circuit ruled in their favor. This case (Apple Computer, Inc. v. Franklin Computer Corp) is still the foundation of US copyright for compiled software. Without it, you could legally download binaries of any software or email them to your friends (and the entire industry would likely look very different). That's why the Franklin has more than earned its place in our vintage computing lab at the @recursecenter.

Continuing my fun with the Enigma machine: I wrote two emulators for a Commodore 64, one in BASIC and the other in Assembly (Turbo Macro Pro, coded on a C64). The BASIC version does about 3 characters per second. The assembly version can encrypt/decrypt roughly 1500 characters per second.

She taught computers how to smile and changed how the world sees technology. Cupertino, 1983. The Macintosh team was building a personal computer for ordinary people, not engineers. The hardware was revolutionary, but there was a problem: computers still felt cold and intimidating. Green text on black screens. Cryptic commands. No warmth. No welcome. Steve Jobs wanted the Macintosh to feel different approachable, even friendly.Someone suggested Susan Kare. She wasn’t a programmer. She wasn’t an engineer. She was a sculptor and graphic designer with a fine arts PhD. She had never designed software. Jobs offered her a short-term contract to create a few icons for the new machine.She said yes. At the time, the Macintosh screen measured just nine inches diagonally, with a resolution of 512 by 342 pixels. Every icon had to fit into a tiny 32-by-32 pixel grid, in black and white. There were no established conventions. No visual language for graphical interfaces. Susan wasn’t refining a system she was inventing one. She began with graph paper. Each square represented a pixel. She sketched carefully, testing shapes that could communicate meaning instantly. A trash can for deleting files. A folder that resembled the manila folders found in offices. A document that looked like a sheet of paper. A floppy disk for saving work. Visual metaphors rooted in everyday life. Then she created the smiling Macintosh face—the “Happy Mac.” When users turned on their computer, it greeted them with a smile.It was a small detail. It changed everything. Until then, computers had no personality. Susan gave the Macintosh warmth. She understood that technology adoption isn’t just about power or speed—it’s about comfort. People needed to feel invited, not intimidated. Her influence extended beyond icons. She designed typefaces for the Macintosh, naming them after cities Chicago, Geneva, Monaco. Chicago became the system font seen by millions for decades. She created the Command key symbol based on a Scandinavian campsite marker so it would feel universal rather than language-specific. She even designed the whimsical “dogcow” graphic in the print dialog box an unnecessary but charming detail that made users smile. When the Macintosh launched in 1984, its friendliness stood out. The interface felt intuitive because it was built on visual metaphors people already understood. Other companies quickly followed. Microsoft Windows adopted similar icon conventions. The visual vocabulary Susan created became the foundation of modern user interface design. Decades later, we still use her language. The trash can icon. The folder. The floppy disk symbol for saving long after floppy disks disappeared. Her early pixel sketches shaped the way billions of people interact with technology every day. Susan went on to design for NeXT, Microsoft, Facebook, Pinterest, and others. In 2015, she received the National Design Award for Lifetime Achievement. Her original Macintosh icon sketches now sit in the Museum of Modern Art. She proved that design is not decoration it is communication. It bridges complexity and clarity. It transforms tools into companions. Before Susan Kare, computers were machines. After Susan Kare, they smiled.And once technology learned to smile, the world was finally ready to embrace it.

Today in 1925, #ACMTuringAward recipient Douglas Engelbart was born. Engelbart received the Turing Award in 1997 for his inspiring vision of the future of interactive computing and the invention of key technologies to help realize this vision. Engelbart invented or helped pioneer foundational technologies of modern computing, including the computer mouse, hypertext, windowed and split-screen interfaces, interactive text editing, email, and groupware. At Stanford Research Institute, he led the development of the oN-Line System (NLS), famously demonstrated in the 1968 “Mother of All Demos,” which helped define computer-supported collaborative work and shaped personal computing and the Internet.
