   Well, along with, traditionally, 6502 and Z80, and MSP430.   
      
   The Atmel AVR was also pretty popular for a while, though AFAIK more in   
   the hobbyist space (say, more popularity due to Arduino than due to its   
   use in consumer electronics). Whereas the MSP430 was fairly widespread   
   in the latter (and a fairly common chip for running things like mice and   
   keyboards).   
      
   There were more advanced versions of the MSP430, with a 20 bit address   
   space, etc. But the most readily available versions typically used a   
   16-bit address space (with typically between 0.25K and 2K of RAM; and 1K   
   to 48K of ROM).   
      
      
   In most cases, one got C with a similar programming model; namely 'int'   
   being 16 bit. Though, the Arduino platform used C++.   
      
   I was left thinking that I had still seen a lot of K&R style C in the   
   6502 and Z80 spaces, but can't seem to confirm.
