- Parker Brothers Split Second
- * TMS1400NLL MP7314-N2 (die labeled MP7314)
-
- This is an electronic handheld reflex gaming device, it's straightforward
- to use. The included mini-games are:
- 1, 2, 3: Mad Maze*
- 4, 5: Space Attack*
- 6: Auto Cross
- 7: Stomp
- 8: Speedball
-
- *: higher number indicates higher difficulty

- Parker Brothers Bank Shot (known as Cue Ball in the UK), by Garry Kitchen
- * TMS1400NLL MP7313-N2 (die labeled MP7313)
-
- Bank Shot is an electronic pool game. To select a game, repeatedly press
- the [SELECT] button, then press [CUE UP] to start. Refer to the official
- manual for more information. The game selections are:
- 1: Straight Pool (1 player)
- 2: Straight Pool (2 players)
- 3: Poison Pool
- 4: Trick Shots
-
-
- TODO:
- - bankshot: the cue ball led is strobed more often than other leds,
- making it look brighter. We need more accurate led decay simulation
- for this to work.
- - MCU clock is unknown
