I just wrote a brief article with pictures, taking a look at some Ending Man clones I have, particularly the S-500 series:

Fantastic finally a story about those mystic famiclones (we in ex Yugoslavia and Bulgaria had those clones in 90s but only NOACs so it is very interesting for me personally to know more about earlier versions Thanks man!  

Edit
I noticed that on several pictures there is no X-TALs on the early clones , strange , how they work without it?
Also did you know about RF Antenna (the hole on the back left side is for it) and headphone output on some joysticks And there is 3rd most popular clones of ending man with 3 separated boards much smaller then your examples NOAC based
interesting think is that the newest clones of endingman clone of a clone do not have even LED, eject leaver is fake and the console is little smaller and the plastic is brittle and the hole clone is total rubbish 
Those clones of a clones even have fake AV outs, and newer ones do not have RF at all
They have poor video and audio quality as well.
I posted a topic about this  you can see it here https://www.famicomworld.com/forum/index.php?topic=13660.0

Is there anything soldered under the board? My guess, this is "region select" - CPU and PPU are socketed, board wave soldered and XTAL added by hand for PAL or NTSC.
