In 1986, Acorn shipped the ARM Development System, the world’s first ARM development board to ever be sold with an ARM Processor in it, a Tube-linked second processor for the BBC Master which allowed developers to write programs for ARM! Sophie Wilson, original ARM designer at Acorn Computers, talks about the History of ARM, with the devices that used ARM1, ARM2, ARM3, ARM610 in the Apple Newton and talking about how ARM was spun out of Acorn, how the ARM business model made ARM such a huge worldwide success.
