This chapter describes software emulators for the Pilot ACE. The first known software emulator of the Pilot ACE was built in Visual BASIC by Donald Davies in the early 1990s. In spring 2001, two graduate students at the University of San Francisco, Athena Huang Shih-Yun and Nicola Rugai, ported Davies's code to Java as part of their Master's Project. Huang wrote additional Java code and improved and extended the interface. The improved emulator was written for The Turing Archive for the History of Computing and was inspired by the desire to offer a Pilot ACE emulation in a platform-independent format. Huang subsequently adapted the Pilot ACE emulator to the architecture of the Big ACE.
