*
*   CoCo XT Hard Disk Driver  07/25/87
*
*   For Western Digital WD1002-WX2 (or WX1) Controller.
*
*   This version is optimized for 1 4x32 hard disk
*   on the CoCo 2, under level 1, version 1 OS9.
*   It does not mess with the clock speed -- it uses 
*   the native speed.  It does not verify disk writes, 
*   and does not use read caching.
