Throttle type B

You can have max 2 Type-B throttles per game card. The Type B Throttle will use two throttle numbers. E.g. if you want to use a Type-b throttle as throttle number 1, it uses both the #1 and #2 lines on the screen. Throttle number 2 will be unavailable. If you use #4 as a Type-B throttle, #5 will be unavailable. The last throttle in your system, (#4 in a one game card system, and #8 in a two game card system), can not be used as a Type-b throttle.
