MIDI & power Fatar TP100LR 88 keys

I have gotten a completely naked Fatar TP100LR keyboard, 88 keys.
No case, no electronic boards, no power.

I want to add power & MIDI to this.

Attaching/linking pinout diagrams.

Is there a MIDIbox product, that would help me realize this?
And how do i go about powering everyting?

Any help is appreciated, including links to other product than here. I’d prefer to do it all by myself, though. Thank you!
