Notes

main PCB is marked "CS217" and "20520/1L" and is labeled "09900278"
sub PCB is marked "CS218" and is labeled "10901903"
From Piero Andreini: 

Memory map is:
Address		Name	Pos	Fluke CRC
0000-03FF	MR21	6F	3620
0400-07FF	MR22	6H	017D
0800-0BFF	MR25	6L	8464
0C00-0FFF	MR24	6N	FD3D

RAM should be from 1C00 to 1FFF

All components are dated "1979", it's a color game (as opposed to B/W Taito's "Depthcharge" or Gremlin's "Sub Hunter"), so we can assume release year to be 1979.

update 20210426: from Cuavas and Tafoid: the Model Racing Sub Hunter PCB has been stripped for parts, it's missing the main RAM (only text layer RAM present which the CPU can't read back), and one PVI.
added schematics

update 20210601: from Alessio: there is a fully working original cabinet in Alessio's arcade collection.
Confimed that there is a difference between schematics and real hardware.
On schematics there are:
2x 2636 main PCB N5 - Programmable Video Interface
8x 2112-2 main PCB G8,G9,H8,H9,L8,L9,M8,M9
which are not present on the real working PCB.
