NOTES:
1. The +18v DC power supply runs OK on +12v.  It is not connected on SI part II boards.
2. The Power-On-Reset (top board pin 10) must be tied to earth or the game will not run!
This may result in the game making noises and a blank/garbage screen for up to 10 seconds.
A better way is to simulate the POR using the circuit shown to the right:*** Disclaimer ***  This document is supplied for information only and I cannot be held responsible for any damage
