AAM:       OPCODE: d4,0a     OPCODE VARIANT


       This instruction regularly performs the following action:
       - binary number in AL
       - AH = AL / 10d
       - AL = AL MOD 10d

       Thus creating an unpacked BCD in AX.
       The normal opcode decodes as follows: d4,0a
       The instruction itself is an instruction plus operand. By
       replacing the second byte with any number in the range 00 -
       ff we can build our own instruction AAM for various number
       systems in that range. For example by coding d4,07 we
       achieve an instruction that performs: AH = AL / 07d, AL = AL
       MOD 07d

       The AAD and AAM opcode variants have been found in Future
       Domain SCSI controller ROMS.
