That maybe true. I also maybe confusing the HC05 and the HC11. After some thought and a 
bit of research I found that the M6805 was ofered in both MC6805 and MC68HC05. Now 
almost totally replaced by the MC68HC08 and its variants. I may have been thinking of the 
HC05 migration and associated it to the HC11. With the advent of numeric and data paging 
the MC146805E was the processor then in the early 80's. Also I remember that the 
MC146805E was used early in numeric paging. I think it was around the mid to late 80's that 
the HC11 took off in paging. I know for the alpha line of pageers and for Flex Protocol we 
used an HC05WJ as a DSP processor and then a HC11PH8 as a backend processor.
