Others
1x 18x2 edge connector (main PCB)
2x 50 pins flat cable connectors from main PCB to ROMs PCB (CN1,CN2)
1x trimmer (volume)(main PCB VR1)
1x 8 DIP switches bank (main PCB ic11)
Notes
main PCB is marked: "assa 811" and "PL-01" on component side
ROMs PCB is marked: "PL-02" on component side
main PCB is labelled: "N.208" on component side
partially working
label format is: ------------ | 09 - 811 | -> ROM number - game number ------------
The background music is "Greensleeves" (google it). The only difference I can see from a "normal" Phoenix PCB is the MN6221AB instead of the MN6221AA.
Same music as Phoenix (Amstar, different music)
