  About
  --------------------------------------------------------------------------

    This archive includes source code for decoding an IBM compatible
    AT keyboard into ASCII which is sent at 9600 BPS using a 4MHz
    crystal.
    
    Included in this archive should be the following 3 files,

    KEY05R2.TXT - This File.
    KEY05R2.ASM - Assembly Source Code for HC705J1A
    KEY05R2.LST - List file.
    KEY05R2.S19 - .S19 file.

    During development, the KEYBRD05.ASM file was assembled using CASM5J1A,
    a dedicated 68HC05J1A assembler. This assembler has equates for the
    HC705J1A's ports built in. If using other assemblers, you may be
    required to specify the port addresses.

    Should you have trouble assembling the code, a .S19 File is also
    included.
