2x SY2114L-3 ROMs PCB ic26,ic28

PLDs

QTY Type position status
0x

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)
