[Identity?] got MB with a Socket7 and Slot 1

[Patrick.B (TTR)]

I have this board below and it seems to have a slot 1 and a socket 7, I am assuming it is a 486/586 Motherboard based on the Bios alone.
I have searched visually on Total Hardware 1999 website https://th99.infania.net/ and could not identify the board from its characteristics
4xPCI, 4x ISA 32bits. 2 IDE, 1 FDD, 2 Serial, 1 LPT, 1 PS/2 and an odd "power connector next to the CPU (for a fan ?)
The only marking on the board is " RT-512K " I would love to have a manual to see if I can revive this board.
Any help is appreciated.

That's a pretty standard Socket 7 board. Supports non-MMX (single-voltage) Pentiums only, as the VRM is not installed. The molex power connector is for CPUs that are very power-hungry (probably only used when the VRM is installed).

The slot next to the CPU socket is not a Slot 1. It's for a COAST module (to get pipeline-burst cache instead of slower SRAM cache).

The brand of the board is "Rectron"

thank you Timo for the great suggestion and manufacturer's name, Il have to find a pentium to try with it...
