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.
