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)
