This is microcontroller chip commonly found on clones till post
pentium packaged in 40 pin DIP. After that, non-legacy and embedded
8042's in chipsets in newer boards and later.

Right now I need the pin info where clock goes into that 8042 so I
could bypass current clock source. Motherboard's clock generator is
sick. Most of it is partially working, which is very common on one
brand chipmaker. !! Do it by injecting 8042 directly with crystal
xtal or use 4 pin oscillator ic. Need Mhz as well, 12Mhz?


Pin 2 is X1 (clockin) and Pin 3 is clock out.

Same pinout as 8041/8741/8742
