The Namco System 11 system comprises 3 PCB's....
MOTHER PCB- This is the main PCB. It holds all sound circuitry, sound ROMs, program ROMs, shared RAM, bank-switching logic,
            controller/input logic (including sound CPU).
            There are two known revisions of this PCB. The differences are not known, though they're probably almost identical except
            for some minor component shuffling. The 2nd revision is used only by Kosodate Quiz My Angel 3 and Star Sweep.
CPU PCB   - There are two known revisions of this PCB. Any game can use either PCB. Contains main CPU/RAM and GPU/Video RAM
            The differences are only in the RAM type, one uses 4x 16MBit chips compared to the other that uses 2x 32MBit chips.
ROM PCB   - There are two known revisions of this PCB. They're mostly identical except one uses all 32MBit SOP44 MASKROMs and the other
            uses 64MBit SOP44 MASKROMs. The 64MBit ROM board also has space for a PAL and a KEYCUS.

Each game has a multi-letter code assigned to it which is printed on a small sticker and placed on the bottom side of the MOTHER PCB.
This code is then proceeded by a number (1, 2, 3 & 4 seen so far), then 'Ver.' then A/B/C/D/E which denotes the software
revision, and in some cases a sub-revision such as 1 or 2 (usually only listed in the test mode).
The first 1 denotes a Japanese version, other numbers denote a World version.
For World versions, only the main program changes (and sometimes only some of the program ROMs change), the rest of the (graphics) ROMs
use the Japanese version ROMs.
See the Main PCB and ROM Daughterboard PCB texts below for more details.

Notes:
      The 2nd revision CPU board (GP-13 COH-110) uses 2x 32MBit RAMs instead of
      the 4x D482445LGW-A70 RAMs and the 2 main SONY IC's are updated revisions,
      though the functionality of them is identical. The 2 types of CPU boards can be
      used with any System 11 motherboard, and any System 11 game.

Notes:
      S11MOT* = Standard System 11 PALs
      WAVE ROM is 42 pin DIP either 16MBit or if 32MBit it's Byte Mode.
      SPROG ROM type is Intel PA28F200BX 2MBit Flash
      PRG ROM type is Intel E28F008SA 8MBit Flash
      CONN1 is for connection of the ROM Board
      CONN2 is for connection of the CPU board
      There is a REV B Mother board (SYSTEM11 MOTHER(B) PCB) with slightly different
      component placings. It's not known if it has different components also.

Notes:
      This ROM board is wired to accept 8Bit x 32MBit SOP44 MASK ROMs.
      There is another ROM board (ROM8(64) PCB) which is wired to accept 64MBit SOP44 MASK ROMs
      and the IC locations are slightly different also.
