Stun Runner ----------- In order to use existing coin software: 1. The Coin Switches will be connected to the MultiSync Board instead of to the SA II. 2. One end of the Coin Counter will be connected to the Coin Counter driver on the MultiSync Board. The other end will be connected the CC1+ on SA II to pick up +14V through a resistor. Carole will find out if the Counter Counter has an internal protection diode. If it doesn't, she will put one at the Coin Counter Connector. Carole will add a power ground from SA II to the MultiSync Board to augment the ground in the SCUM Cable. The Stun Runner current requirement from the +5 Volt supply is 7.5 Amps. Rick Meyette assures me that tne +5 Volt 10 Amp supply is rated to supply 10 Amps up to 50 degrees Celsius. Therefore, Stun Runner can use the +5 Volt 10 Amp supply. I have obtained a series number for Stun Runner Programmed Parts. I have received a memo on diagnostic test results from RPM. I need to know: 1. What is the protocol for communicating to SA II? 2. How do I call S_STAT? 3. Is there a period after which, with no reponse, I can assume the SA II is broken? 4. The Status bits indicate three ROMs (at 4000, 8000, and C000). The SA II schematic shows only one program ROM. If this ROM is good will all three ROM status bits be set or just one? If one, then which one? 5. The situation for RAMs is similar. 6. Does the SA II program deliver ROM checksums? 7. Does the SA II test the ROMs connected to the MSM6295? Jed

Jed, I want to let you know that the coin counter on the STUN cabinet is connected the way you want it, and it seems to work fine. I didn't look at the signals yet to see if any noise is injected into the MSYNC bd from the grounding method we use. I haven't noticed anything strange happen to the game when the coin counter is activated, like resets that you were worried about. We have another monitor now. This one seems to be much better than the last monitor, which was too dark. We also connected the development system to the game to look at the pot values, and were able to zero the vertical aim pot with this data. The game seems to be working fine at this time. Thanks, Glenn.
