    MAGIC CARD - IMPERA
    -------------------

    Preliminary driver by Roberto Fresca, David Haywood & Angelo Salese


    Games running on this hardware:

    * Magic Card (set 1),  Impera, 199?
    * Magic Card (set 2),  Impera, 199?

*******************************************************************************


    *** Hardware Notes ***

    These are actually the specs of the Philips CD-i console.

    Identified:

    - CPU:  1x Philips SCC 68070 CCA84 (16 bits Microprocessor, PLCC) @ 15 MHz
    - VSC:  1x Philips SCC 66470 CAB (Video and System Controller, QFP)

    - Protection: 1x Dallas TimeKey DS1207-1 (for book-keeping protection)

    - Crystals:   1x 30.0000 MHz.
                  1x 19.6608 MHz.

    - PLDs:       1x PAL16L8ACN
                  1x PALCE18V8H-25


*******************************************************************************


    *** General Notes ***

    Impera released "Magic Card" in a custom 16-bits PCB.
    The hardware was so expensive and they never have reached the expected sales,
    so... they ported the game to Impera/Funworld 8bits boards, losing part of
    graphics and sound/music quality. The new product was named "Magic Card II".

*******************************************************************************

TODO:

-Proper handling of the 68070 (68k with 32 address lines instead of 24)
 & handle the extra features properly (UART,DMA,Timers etc.)

-Proper emulation of the 66470 Video Chip (still many unhandled features)

-Inputs;

-Unknown sound chip (it's an ADPCM with eight channels);

-Many unknown memory maps;
