The defeater circuit in the Honeybee adapter was tested on five revisions of the CIC chip. CIC REV | DATE CODE --------+--------- 3193 | 8641 AC 3193A | 8718 A 6113 | 8741 A 6113A | 8914 7 BA 6113B1 | 9002 5 BA The defeater circuit will not work if the NES motherboard has a diode tied to the CIC data line coming from the cartridge. Mymotherboard is NES-CPU-07 and has this diode installed at C2. I lifted this diode out of circuit and was able to defeat onlythe earlier revision CICs 3193 and 3193A.The resistors appear to do absolutely nothing. I tested with them in circuit and removed completely and saw no functional difference.There was no measurable change in noise on either VCC or GND lines with the resistors in or out of circuit. No resistance couldbe measured between any of the resistors and the capacitor with my Pinball cartridge installed.3193 Will start almost every time on start-up. 3193A Will start almost every time on start-up. 6113 Could not boot game. One long and one short period between console resets. 6113A Will boot game but only after several attempts. Many times it will not boot. One long and one short period between console resets. 6113B1 Will boot game but only after several attempts. If it doesn't boot within a few seconds it seems like it never will. Occasionally it will hang in a reset state and the power LED will be off.
