Notes: (all ICs shown)

       VG230    - Vadem VG230 single-chip PC platform. Contains 16 MHz NEC uPD70116H V30HL CPU
                  (which is a high-speed low-power 8086 variation), IBM PC/XT-compatible core
                  logic, LCD controller (CGA/AT&T640x400), keyboard matrix scanner, dual PCMCIA
                  2.1 card controller, EMS 4.0 hardware support for up to 64MB, built-in timer
                  PIC/DMA/UART/RTC controllers. The clock input is 32.2200MHz. An internal divider
                  creates a 16.11MHz clock for the V30HL CPU.
       HM514800 - Hitachi HM514800 512k x8-bit DRAM
       MC14071  - Motorola MC14071 Quad 2-input OR gate
       74HC04   - 74HC04 Hex inverter
       LM2937   - Texas Instruments LM2937ES-5 voltage regulator (Max 26V input, 5V output at 500mA)
       CE-0702  - TDK CE-0702 DC-DC converter for LCD in SIP9 package (5V input, -24V output at 25mA)
       POWER    - 9V DC power input from AC/DC adapter
       VOL      - Volume pot
       CN5      - 5 pin connector for 4-way control pad (up/down/left/right/ground)
       CN4      - 5 pin connector for on/off switch and 2 buttons
       CN3      - 2 pin power input from 6x AA-battery compartment (input voltage is 9V DC)
       CN2      - Flat cable connector for video out to LCD panel. When the LCD is powered on the pixels
                  are blue. The LCD panel PCB has part number 97-44264-8 LMG6912RPFC LMG6910RPGR
                  and contains the following parts.....
                  Matsushita 53008HEB-8
                  Sanyo LA6324N quad operational amplifier
                  Hitachi BD66285BFC LCD controller IC (x3)
                  Hitachi BD66284BFC LCD controller IC (x4)
                  The LCD flat cable has several wires but 2 of them have frequencies which measure
                  69.9161Hz and 16.7798kHz. These are assumed to be VSync and HSync
       CN1      - Cart slot
       X1       - Marked 322. Measures 32.21732MHz so this is a common 32.22MHz OSC.
       X2       - No markings. Measures 32.768kHz and used for the RTC
       *        - These parts are on the other side of the PCB


Carts
-----
All of the carts are identical. Most have only one surface mounted mask ROM. Either a
MX23C8100 (8M) or YRM0442 (4M). Some are populated with additional parts including a 62256
32kx8 SRAM, a 3v coin battery and a MM1081N reset chip plus a few resistors/capacitors and
a transistor. All parts are surface mounted.

Notes:
      Carts containing just one mask ROM are KS-1002, KS-1003, KS1004 and KS-1009
      Carts containing RAM, battery and reset chip are KS-1001 and KS1010
      Carts KS-1005, KS-1006, KS-1007 and KS-1008 probably exist but are unknown.

 PeT mess@utanet.at march 2008

although it is very related to standard pc hardware, it is different enough
to make the standard pc driver one level more complex, so own driver

TODO:
- Make a separate device of the Vadem VG230 core (it is also used in the HP
  OmniGo 100 and 120).
