TRS-80 Color Computer 2 with Extended Color Basic or Disk Extended Color Basic.  
* Plain 'Color Basic' will not work!
* Color Computer 1 will not work, unless it has been upgraded.

Preferred Emulator: XROAR
Preferred ROMs: Color Basic 1.3 with Extended Color Basic 1.1 

http://www.colorcomputerarchive.com/coco/ROMs/XRoar/CoCo/BASIC_OS/
    (bas13.rom and extbas11.rom)

A sample xroar.conf file is provided for convenience. 

To run in XROAR:  

When XROAR is configured properly, it should read "EXTENDED COLOR BASIC 1.1" at
power on.  If you get a "COLOR BASIC 1.x" greeting instead, not all the ROMs are
being loaded correctly.  If the emulator starts with a garbled screen, none of
the roms are being loaded.

In XROAR, Go to the File Menu and Select Load.  Choose the KABOOM-10.BAS file.
This loads the file in the virtual cassette buffer.
In the emulator type CLOAD.  The screen should say 'BASIC F', pause for a bit,
and then give you back to an OK prompt.  Type RUN.  Note:  Sometime CLOAD will
give an IO error.  Try File/Load again, and then CLOAD again, and it will 
probably work.  I think XROAR has a bug!

Also, it assumed the machine running this is freshly powered on.  There are 
certain system settings (changing the size of string space and video ram) that
other programs may have done, and this program is too short to undo any of that.
