The graphing calculator (also known as NuCalc) program they'd been working on for new mobile devices had finally been shelved, and they could all move on.
But Ron Avitzur didn't despair. After Apple cancelled his project, he, together with his friend Greg Robbins, continued to work for free, sneaking into the building every day in order to continue development of the software. When completed, the software was so impressive that Apple executives used it as their standard demonstration of the then-new PowerPC chips.
