 TODO: implement the RESET key on the front panel
       find a dump of the character ROM
       convert the drawing code to tilemap


 1. General
   SYSTEM
- Signetics 2650 CPU at 3.58/4 MHz(for NTSC) or at 4,433/5 (for PAL)
- 1k x 8 of RAM (physically present but only 512 byte available)
- 2 x 2 axis Analogue Joysticks
- 2 x 12 button Controllers
- 3 buttons on system unit and CPU Reset
   VIDEO
- 128 x 208 pixel resolution (alternate 128 x 104 mode available)
- 16 x 26 (can be 16x13) background display (2 colour 8 x 8 pixel characters)
- 4 x 8 x 8 Sprites (2 colour 8 x 8 pixels)
- total of 8 user defined characters available
   SOUND
- Single channel beeper


2. Memory map
The memory map of the 2001 is below.
0000 - 0FFF 4k ROM Block 1 (first 4k of a cartridge)
1000 - 13FF     mirror of $1800-$1BFF
1400 - 17FF     mirror of $1800-$1BFF
1800 - 1BFF     UVI2637 Area (detail description in video/arcadia.c)
    1800 - 18CF     Screen display , upper 13 lines, characters/palette high bits
    18D0 - 18EF Free for user programs.
    18F0 - 18F7     Sprite coordinates y0x0y1x1y2x2y3x3
    18F8 - 1908     registers of UVI
    1909 - 197F     Unmapped
    1980 - 19BF     User defined characters (8 possible, 8 bytes per character)
    19C0 - 19F7     Unmapped
    19F8 - 19FF     registers of UVI
    1A00 - 1ACF Screen display , lower 13 lines, characters/palette high bits
    1AD0 - 1AFF User memory
    1B00 - 1BFF     mirror of 1900-19FF
1C00 - 1FFF     mirror of 1800-1BFF
2000 - 2FFF 4k ROM Block 2 (for 8k carts such as Jungler)
3000 - 3FFF mirror of 1000-1FFF
4000 - 4FFF mirror of 0000-0FFF
5000 - 5FFF mirror of 1000-1FFF
6000 - 6FFF mirror of 0000-0FFF
7000 - 7FFF mirror of 1000-1FFF

The Palladium VCG memory map is as follows.
0000 - 0FFF 4k ROM Block 1 (first 4k of a cartridge)
1000 - 17FF     could be ROM or RAM but no Cartridge uses this
1800 - 1BFF     UVI2637 Area (detail description in video/arcadia.c)
    1800 - 18CF     Screen display , upper 13 lines, characters/palette high bits
    18D0 - 18EF Free for user programs.
    18F0 - 18F7     Sprite coordinates y0x0y1x1y2x2y3x3
    18F8 - 1908     registers of UVI
    1909 - 197F     Unmapped
    1980 - 19BF     User defined characters (8 possible, 8 bytes per character)
    19C0 - 19F7     Unmapped
    19F8 - 19FF     registers of UVI
    1A00 - 1ACF Screen display , lower 13 lines, characters/palette high bits
    1AD0 - 1AFF User memory
    1B00 - 1BFF     mirror of 1900-19FF
1C00 - 1FFF     could be ROM or RAM but no Cartridge uses this
2000 - 2FFF 4k ROM Block  (for 8k carts such as Jungler)
3000 - 3FFF could be ROM or RAM but no Cartridge uses this
4000 - 4FFF 4k ROM Block  (first 2K used by Golf)
5000 - 5FFF 4k ROM Block
6000 - 6FFF 4k ROM Block
7000 - 7FFF 4k ROM Block


3. ROM Images
ROM Images are loaded into 0000-0FFF. If the ROM is an 8k ROM the
second half of the Rom is located at 2000-2FFF. Except for the Golf cart
which is located from 0x0000-0x0FFF and a 2kbyte block from 0x4000 only on
Palladium VCG.


4. Controls
All key controls are indicated by a bit going to '1'. Unused bits at
the memory location are set to zero.

Keypads

1900-1902 (Player 1) 1904-1906 (Player 2)
The keypads are arranged as follows :-

        1       2       3
        4       5       6
        7       8       9
      Enter     0     Clear

Row 1/4/7 is 1900/4, Row 2/5/8/0 is 1901/5 and Row 3/6/9 is 1902/6
The topmost key is bit 3, the lowermost key is bit 0.

Location $1908 contains bit 0 Start,bit 1 Option,bit 2 Difficulty.
These keys are "latched" i.e. a press causes a logic 1 to appear
on the current frame.

The fire buttons are equivalent to Keypad #2 e.g. they are 1901 and
1905 bit 3.

Palladium has 4 additional key per keypad which are mapped at
1903 palladium player 1
1907 palladium player 2


5. Other information
Interrupts are not supported
The Read/Write 2650 CPU Port-Commands do not appear to be connected to
anything in hardware. No cartridge has been found which uses them.
