Notes

main PCB is marked: "CVS MAIN LOGIC", "500-36 ISS 3" and "PCP" on solder side
sound PCB is marked: "CENTURY SPEECH/SOUND", "500-38 Iss 2" and "(C) 1981 ALL RIGHTS RESERVED" on component side
sound PCB is marked: "CVS SPEECH SOUND 500-38 Iss 2" and "PCP" on solder side
ROMs PCB is marked: "CVS MEMORY", "500-40" and "(C) 1981 Al Rights Reserved" on component side
ROMs PCB is marked: "PCP", "500-40" and "CVS MEMORY" on solder side
main PCB is labelled: "Serial No. 0690" on component side
On ROMs PCB position SP2 is empty
This PCB has the name "SPACE FORTRESS" on the ROMs module, and came with a "SPACE FORTRESS" marquee. Despite all of those, the game is clearly "Cosmos".
The marquee is marked by Tuni Electro Service Inc. which was the US dealer for Century Electronics.

---

label format (on ROMs PCB) is:
----------------
|Century Elect.| -> manufacturer
|Ltd. (C) 1981 | -> copyright and year
| 1B-9         | -> rom number
----------------

update 20190616: better description and correct identification as "Cosmos" (it was "Space Fortress" previously)
