The V30 was not an "upgrade" in the traditional sense--it was a pin-
for-pin CMOS replacement for the 8086.  Because of some internal 
architectural features, it ran somewhat faster than an 8086 of the 
same clock speed and implemented many of the 186 instruction set 
additions.  It also had an emulation mode for running 8080 code.

There were more 8086 mobos than you might imagine.  Consider, for 
example, the Stearns PC.  Since there was a CMOS 80C86 available 
before the 80C88, the 8086 also found its way into several laptops.

There were also a few NEC V40 machines.
