      CN15       - Standard (PC-compatible) 40 pin IDE CDROM flat cable connector and 4 pin power plug connector,
                   connected to Panasonic CR-583 8-speed CDROM drive.
      LA4705     - LA4705 Power Amplifier
      DSW        - 8 position dip switch
      BOOTROM.8Q - 16MBit MASKROM. Location 8Q (DIP42)
                   Battle Tryst       - 636A01.8Q
                   Evil Night         -       .8Q
                   Heat Of Eleven '98 -       .8Q
                   Polystars          - 623B01.8Q
                   Total Vice         -       .8Q
      93C46.7K   - 128bytes x8bit Serial EEPROM. Location 7K (DIP8)
                   NOTE! There is very mild protection to stop game-swapping. It is based on the information in the EEPROM
                   being the same as the Time Keeper NVRAM.
                   For example, in Evil Night, the first line of the NVRAM in hex is 474E38313000000019984541410002A601FEFE01
                   Looking at it in ascii:  GN810.....EAA.......
                   Hex 474E383130 = GN810
                   1998 = the year of the game
                   Hex 454141 = EAA (the version = europe english)
                   The numbers after this appear to be unimportant (at least with regards to swapping games anyway).
                   All the other data after the first line is used for high scores tables etc.
                   The important part is that the data in the EEPROM should be the same as the NVRAM, but the EEPROM data
                   is byte-swapped! If the two don't match, the check on 7K or the NVRAM will fail and the PCB will reboot
                   forever.

Some lower boards have two connectors underneath for a protection sub-board or sound board. These are detailed below....
