PST518B in a CD1 system.

The Mitsumi PST518B is a reset generator, it holds the NeoGeo in reset as long as the power supply is below 4.4V.

It has an open-collector output tied to RST (not RESET !), which is shared with the reset button on the AES. The signal goes to NEO-B1.

Datasheet: File:PST518B.pdf.

Not to be confused with the watchdog reset.
