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.
