I have my doubts that it's a genuine ES chip, as the font used for the ES stamping is different from the rest of the chip. Look at the middle line of the E. You will see it's shorter than the other two horizontal lines, but it's the same length as the other lines on all the other Es on the chip. On other ES Am386 chips I've seen the E in ES matches all the other Es.

Date checks out, very early,, earlier then mine by a few weeks
Stepping is correct for the age too (C step came out week 30ish)
