the 68HC11 seems to be everywhere--and the 6502 has
been pretty
much relegated to obscurity.
The reason you don't see it is that the part number oftem bears no
similarity to 65x02. All the Mitsubishi 740 series and ITT CCU3000
series ucontrollers were 6502 cored as are a lot of Rockwell modem
chips. Every BSB D2MAC receiver had two 6502 chips, one in the CAM
badged GEC, Sharp TVs and Videos used them.
In non computing equipment the most popular CPU core seems to be the
8031/51, 6502 and Z8,

...and the 68HC11 and its kin are still in use in modern designs. While
there undoubetdly (due to the sheer volume of CBM, and Apple systems) far
more applications of 6502s in PC's, the 6800-based embedded applications
far outnumer 6502-based ones. My point was that on the basis of
instruction set alone, one would have expected the reverse to be true.

The TEWS in the F-15 is based on a 1Mhz 6800B.

I'll make the strong arguement that in non-computing equipment,
it is Japanese 4-bit CPU cores that still dominate. They did up
until recently and are still VERY strong. Things like the NEC
75000 series. Every cheap little novelty that plays awful music
or sound effects, or blinks lights has one in it. And the control
panel on every consumer device is driven by one, i.e. microwave
ovens, etc.
There is still a market for low cost 4-bit processors. If you
want to order one, though, you'd better want to order quantities
in six or seven figures. (And have your code ready for the
masking.)
