Replying to a message of Glen McNabb to Darryl Gregorash:
 SM>>> Apparently, on the NEC chips [V20/30]
  SM>>> supposedly the AAM and AAD instructions don't work
 SM>>> correctly for any operand other than 0x0A.
 DG>> ...they ignore that byte.. decimal values only.
 GM> That's been my experience with it. The only use I ever had
 GM> for using a data byte other than 0A was to unpack the
 GM> values into nibbles for dual BCD displays.
Also good for testing to see if you had a V20/30 or an Intel.. if AAD with 
any operand  gave you the result you expected for a decimal adjust, then you 
had a NEC chip.
