   The 80186 is a very popular (and current) chip in the "deeply 
embedded" (my term) world...things like hard drives and such.  It's 
little more than an 8086 with a DMA controller, interrupt controller, 
and a few other things on the same die.

   Take pretty much any SCSI drive from the 2GB-9GB (or so) range and 
flip it over...chances are you'll see an 80186 on the board, probably 
from AMD.
