MAME emulates a variety of old computer hardware, Dragon included. Source available.

T3 and PC-Dragon, two DOS-only emulators. Source code is available for PC-Dragon, but redistribution of modified copies is not permitted, amongst other restrictions. T3 is closed source (I believe it was written in x86 assembly). These links are to a software collection site, as the original seems to have disappeared.

VCC, a Windows-only CoCo 3 emulator. Does not emulate CoCo 1/2 (beyond what compatibility 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 at once.

OVCC develops the open-sourced version of VCC in an attempt to make it cross-platform. CoCo 3 only, like the original.
