CPUs
| QTY | Type | clock | position | function |
|---|---|---|---|---|
| 1x | HD68A09P | main PCB | 8-bit Microprocessor - main | |
| 1x | HD6809EP | main PCB | 8-bit Microprocessor - main | |
| 1x | YM2203C | main PCB | FM Operator Type-N (OPM) - sound | |

| 1x | oscillator | 12.000MHz | ROMs PCB |
ROMs
| QTY | Type | position | status |
|---|---|---|---|
| 1x | TMS2764JL | ROMs PCB 12 | dumped |
| 1x | M27128 | main PCB 4 | dumped |
| 7x | IP27256 | main PCB 1,2,3,5,6,7,8 | dumped |
| 3x | IP27256 | ROMs PCB 9,10,11 | dumped |

PLDs
| QTY | Type | position | status |
|---|---|---|---|
| 3x | AMPAL16R4PC | ROMs PCB A,B,C | dumped |
Others
1x 22x2 edge connector
2x flat cable connector from main PCB to ROMs PCB
1x trimmer (volume)
2x 8 DIP switches banks
Notes
main PCB is marked: "3002A" on component side
ROMs PCB is marked: "3002B" on component side
ROMs are identical to "Darwin 4078" already in MAME, PROMs are not!
update 20181207 from Osso: The PROM has bitrot problem on 1 bit. For the rest it is identical to what's already in MAME.
