Xcopilot
Xcopilot is a Palm Pilot emulator that runs under Unix/X11. It offers emulation of the timer, serial ports, touch pad and LCD along with Motorola 68000 emulation (m68k), specifically the Freescale DragonBall used in Palm Pilots until they switched to Intel XScale ARM processors (later DragonBalls were based on an ARM core not a 68000 but retained the same name, however were not used by Palm.) Xcopilot was originally developed by Ivan Curtis with contributions from Ian Goldberg, Jef Dionne, Kresten Krab Thorup, and Andrew Pfiffer based on the Windows program Copilot.
