Which 80186? These came in a lot of flavors. Every
letter
following meant a change in pinouts or some feature inside.
All of the 80186's had some amount of select line decoding.
This along made them completely incompatible, pin wise, with
any of the more standard '86 family parts.
Also, V20 and V30 are replacements for 8088/86, not 80188/186 !
