It's closer to the JTM 16K Static RAM, which must somehow have been related to CCS.

Note that while the OP's board has two LEDs, and the board in the maben JTM photo shows only one LED, the pads for a second LED are present on the maben board.

I have one too and went through this awhile ago - unidentified board, looking for manual, found the CCS info and then the JTM info.
