Q0209 was added to the S-spec database.
Interesting that frequency was not a part of original markings. This is very unusual for Intel.

All references I can find for Q0209 list the part as only A80486DX
appears to be earliest for the die shrink from 1.0um CHMOS IV to 0.8um CHMOS V
EDIT >> SXE61 also is same die shrink week 13 1991
so Q0209 is likely a qualification sample for the new core rev
