A new version of my Wang 2200 emulator, version 2.1, was just released after a three year snooze: http://www.wang2200.org/emu.html This version runs on Win XP/Vista, PPC OS X, or i386 OS X. Full source code is included. The big changes are support for large format disk geometries due to emulation of the intelligent disk controller protocol, 2200B mode, the ability to print directly to the parallel port, and a massive code clean up.
