  Hm, interesting topic turn, as the first micro I learned to program was
the 1802.  Compared to the other micros of the day, it was a strange
beast.  But it could run on batteries, which made it great for remote
sensing applications.  I blame it for staying with working in 
microcontrollers as opposed to programming large processor models.

  Each Voyager has seven 1802s in it.  Just about all comm satellites 
launched between 1976 and the mid 1990s use them too.  In fact, the 
Voyager 2 officially passed outside the solar system boundary last 
October, making the venerable 1802 the first micro to go interstellar.  
Intel has some catching up to do. ;)

  I used the 1802 to do keyboard scanning, voice assigning, sequencing,
etc. in around 1980.  Oh, and to make a 2716 EPROM programmer.  Folks
today just don't understand the revelation that were ROMs that needed only
one voltage to work, as opposed to three.
