thats a 92/93 explorer 4L auto ecu. I'm not going to have anything even remotely close for that.

Hopefully someone else sees this and has one thats legible.

Found, if any one happens to be doing some hardware hacking, and there is reference to this chip in tom clouds document.
For my hardware SD48b, this is the missing chip where the DOL output from CPU connects hi/lo 5v to, and drives output to pin #34 12v PWM.
