Here are some KU80486SX-20.
Marked with KRA0.
The corresponding logos of the same type I can find are all KU80486SX-16.
What does KRA0?
Is it sspec? |

I think they are not genuine.
KU486SX must be in QFP196, and (R) and tm marks are absent.
EDIT
Looking for this s-spec some were actually used (soldered on board), so there is a chance they are really 486 with unique pinout.
QFP132 was used for NG80386DX. |
