I noticed the Schematic on tab2 has several bits of info missing or incorrect. the caps behind the motor doesn't have any details and the pins on the IC 89C2051 don't match up with the description. Can you please confirm what is correct. 

Also please don't is P3.1 type indicators as they are confusing. P1 p2 is fine.
