It's an 8-bit ISA I/O card, parallel and serial external connectors.
The chips are labeled "UMC UM82C11" [1] and "UMC UM82450" [2] (two of the latter).
The labels "STK" and "S/N 066095" are printed on the board.
No other labels could be found.

[2] Serial interface?

On the back is one serial and a parallel poort *aka printer)

The header on the top have a side for a joystick outpot.. (just need finding an Joystick bracket)

~ At least it can do black and white~

No, it's the second COM, needs a bracket with 25-pin connector.
There are two UARTs there, and two pairs of 1488+1489 buffers.

A com jumper header is never this wide. Iam certain that a DB25 header is a joystick port is DB25. Serial is DB-9

But it also could be that it is a Second LPT port (thats also is DB25) LPT2

uh, no there are plenty of old machines with DB25 serial ports.

though most of them still connected with 9pin cables to cards iirc.

See eg. this - http://www.uncreativelabs.de/th99/i/A-B/50704.htm

There are two 82450 UARTs, two 1488 buffers, two 1489 buffers - so two COM ports.
