A bit late, but here's what I think this board is, at least according to UH19 filters
ECS 386SX -> http://www.win3x.org/uh19/motherboard/show/2097
There's indeed not much information about this board, but at least you get the original MTL jumper manual.

This is really Awesome! I really appreciate your effort into helping me.
Nice work!
I'm looking forward into fully restoring and repairing my Highscreen Model LCD-386 Portable Computer.
I'll probably start with the built-in LCD screen.
Maybe you guys know where I can reorder a compatible replacement.
It's a 640x200 pixel monochrome (probably) passive matrix display.
It's about 10.6 inches in diameter.
On the PCB behind the LCD panel it reads Japan Citizen CG-640200CG W-7894V-0.
Should I start a new thread regarding the LCD screen?
