    Tropical Angel

    driver by Phil Stroffolino

    IREM M57 board stack with a M52-SOUND-E sound PCB.

    M57-A-A:
     TA-A-xx roms and proms
     NEC D780C (Z80) CPU
     NANAO KNA6032601 custom chip
     NANAO KNA6032701 custom chip
     8-way dipswitch (x2)
     M58725P RAM (x3)
     CN1 - Ribbon cable connector
     CN2 - Ribbon cable connector
     Ribbon cable connector to sound PCB

    M57-B-A:
     TA-B-xx roms and proms
     18.432 MHz OSC
     CN1 - Ribbon cable connector
     CN2 - Ribbon cable connector

    M52:
     HD6803 CPU
     AY-3-9810 (x2) sound chips
     MSM5205 OKI sound chip (and an unpopulated socket for a second MSM5202)
     3.579545 MHz OSC
     2764 Program rom labeled "TA S-1A-"
     Ribbon cable connector to M57-A-A PCB

    New Tropical Angel:
     Roms were found on an official IREM board with genuine IREM Tropical Angel
     license seal and genuine IREM serial number sticker.
     The "new" roms have hand written labels, while those that match the current
     Tropical Angel set look to be factory labeled chips.
