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.
[1] Printer related
[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
~ At least it can do black and white~
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.
