Here are the HDB-DOS 1.4 (DriveWire) ROM images and .WAV files, if anyone would like to try them. I have written an improved installer for the cassette versions. Enter EXEC a second time (after HDB-DOS has been installed) and the reset code will be patched on a CoCo 1/2 so it won't crash if the reset button is pressed.
EDIT: Archive updated on Jan 2nd. Further improved the installer for the cassette versions. Reset code is now automatically patched on CoCo 1/2 machines (no need to enter EXEC a second time). Installer now also supports installing HDB-DOS from floppy disk on CoCo1/2 machines.
EDIT: Archive updated on Jan 4th. This copy of HDB-DOS 1.4 is freshly compiled from the latest source code (The DriveWire R/W source code was updated on the 4th January).
EDIT: Archive updated on Jan 10th. I have further improved my HDB-DOS cassette installer. The Disk Extended Color BASIC 2.1 (DECB 2.1) patches are now applied when HDB-DOS 1.4 is installed on a CoCo 3.
EDIT: Archive updated on Feb 18th. Updated my HDB-DOS cassette installer (v1.2).
Changes for HDB-DOS Cassette Installer v1.2 (Released on the 18th February, 2013):
* Added support for Steve Woolham's CoCo BASIC Upgrade Patch v1.1
* Relocated the 64K reset code to avoid conflicts with HDB-DOS
