Includes emulation of floppy drives, expansion interface, doubler, hard drive, sound, joystick, real-time clock, and more. Runs very fast on slow PC hardware. Note: Older PC hardware with a compatible floppy disk controller is required to use the file transfer utilities.

Massive site with lots and lots of TRS-80 information, start digging - Detailed History - how the TRS-80 started - The Software Search - great way to find what games exist, and basic game info - Scott Adams Adventures - emulators and ROMs Matthew Reed's Emulator - TRS32 - Emulates games perfectly - including sound. Presentation impossible.

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.
