As part of Fast Company’s “1995 week“, I wrote about IBM’s ThinkPad 701, the famous model with an expanding “butterfly” keyboard [which could be stretched from 9.7-inches to 11.5 inches]. By putting full-sized keys in a subnotebook-sized laptop, it solved one of mobile computing’s biggest problems.
IBM discontinued it before the end of the year, and neither it nor anyone else ever made anything similar again. And yet it remains amazing.
Check out this 1995 ad for the keyboard! The article calls the butterfly ThinkPad “one of the best things the technology industry has ever done with moving parts,” and revisits 1995’s race “to design a subnotebook-sized laptop with a desktop-sized keyboard.”
It’s still comically thick, standing almost as tall as four MacBook Airs stacked on each other. That height is required to accommodate multiple technologies later rendered obsolete by technological progress, such as a dial-up fax/modem, an infrared port, two PCMCIA expansion card slots, and a bulky connector for an external docking station… Lifting the screen set off a system of concealed gears and levers that propelled the two sections of keyboard into position with balletic grace… A Businesweek article cited sales of 215,000 units and said it was 1995’s best-selling PC laptop. Yet by the time that story appeared in February 1996, the 701 had been discontinued. IBM never made anything like it again. Neither did anyone else…
As portable computers became more popular, progress in display technology had made it possible for PC makers to use larger screens. Manufacturers were also getting better at fitting a laptop’s necessary components into less space. These advances let them design a new generation of thin, light laptops that went beyond the limitations of subnotebooks. Once IBM could make a lightweight laptop with a wider screen, “the need for an expanding keyboard was no longer essential,” says [butterfly ThinkPad engineer] George Karidis. “It would have just been a novelty.”
The article notes a fan’s open source guides for repairing butterfly Thinkpads at Project Butterfly, and all the fan-community videos about it on YouTube, “from an excellent documentary to people simply being entranced by it.
“As a thing of wonder, it continues to transcend its own obsolescence.”
