101 Key, IBM Keyboard Decoder for 68HC705J1A. 2nd April 1999 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.
