T3 and PC-Dragon, twoDOS-only emulators written by Paul Burgin. Source code is available forPC-Dragon, but redistribution of modified copies is not permitted, amongstother restrictions. T3 is closed source (I believe it was written in x86assembly). These links are to a software collection site, as the originalseems to have disappeared.
VCC, aWindows-only CoCo 3 emulator. Does not emulate CoCo 1/2 (beyond whatcompatibility a CoCo 3 had) or Dragon. Recently open-sourced (August 2015),though at time of writing there's no easy way to clone the entire project atonce.
OVCC develops theopen-sourced version of VCC in an attempt to make it cross-platform. CoCo 3only, like the original.
