+*   CoCo XT Hard Disk Driver  07/26/87
+*   (with formatting capability)
+*
+*
+*   For Western Digital WD1002-WX2 (or WX1) Controller.
+*
+*   This is a general purpose driver.  It can handle
+*   1-2 hard drives, the parameters of which are described
+*   in the device descriptors.  The drives may be of different
+*   sizes.  This version is optimized for the CoCo 2 under
+*   level 1, version 1 OS9.  It does not mess with the clock 
+*   speed -- the native speed is used.  It also verifies disk 
+*   writes, and uses read caching.
+*
+*   THIS VERSION CAN FORMAT THE HARD DISK!  IT ALSO
+*   SUPPORTS WRITE PROTECTION.
