It was quite common to have a decimal adjust instruction in the early 8 
bit microprocessors. The add was done in binary and then the decimal 
adjust instruction was used to "adjust" to valid BCD.

It started with the INTEL 4004 and continued onward 8051/52, 8080, 
8086... The PIC processors had a similar DAW (decimal adjust W reg). 
Also variants in the Motorola 6800 family and the MOS Technology 6502.
