==Notes==
main PCB is marked "CS217" and "20520/1L" and is labeled "09900278"<br>
sub PCB is marked "CS218" and is labeled "10901903"<br>
From Piero Andreini:
<pre>
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</pre>
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: <s>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.</s><br>
added schematics
-----
update 20210601: from Alessio: there is a fully working original cabinet in Alessio's arcade collection.<br>Confimed that there is a difference between schematics and real hardware.<br>On schematics there are:<br>
2x [[2636|2636]] main PCB N5 - Programmable Video Interface<br>
8x [[SRAM 256 x 4|2112-2]] main PCB G8,G9,H8,H9,L8,L9,M8,M9<br>
which are not present on the real working PCB.<br>
