Others

1x 18x2 edge connector (top PCB)
1x 50 pins flat cable connector from top PCB to bottom PCB
1x trimmer (volume)(top PCB VR1.4a)
2x 8 DIP switches banks (top PCB DPSW1.7b DPSW2.7c)

Notes

top PCB is marked: "MADE IN JAPAN" and "M-31-A" on component side
bottom PCB is marked: "CVG-48C" and "1984" and "M-31-B" on component side
This is not a dumping error, the only different EPROM is really a 2764 with 2 identical halves.

update 20180409: better description, OSSO support for 97.4a
