Over the course of my career the company I work for has provided me a number of different computers to do my job, most of them have been pretty cheap devices. However, for a period of time I was provided with IBM Thinkpads including the 701c that had a unique, expanding, “butterfly” keyboard. It has been a long time since I have thought about that computer, but today I read a description of how one was restored. Nobody tries changes to physical designs of computers like they did back in the day.
