Second-generation auto-adjust eddy sensors (1996-1998)

Games from 1996 to 1998 such as Scared Stiff, Cirqus Voltaire and Monster Bash use auto-adjusting eddy boards with no trim pot. They do not drift out of adjustment but carry more logic parts that can fail. They generally plug in where the older manual boards went, though R1 may need changing.
