After long research i could obtain a 8 Bit I/O Card with two internal serial ports and one inter parallel port.
I had the hope to find the Jumper Config on Stason, but without luck.
Maybe someone can help out with some hints.

Big IRQ Jumperblock in the middle is clear (from top to bottom): internal printer; external printer; COM2; COM1
Block on left side, JP 1-4: maybe activation (pos 2/3)/ deactivation (pos 1/2) of COM1-2 & parallel 1-2
Small Block in the middle, JP5/6/9: hmmmmm

Would be glad, if someone can support.

Thanks and best regards
Lutz

Does it have ANY markings at all on the backside that may be a type number?

Without that, educated guesswork starts here:
The ASYNC1/ASYNC2 connectors top left are the serial ports, the PTR is the second printer port.
The four row jumper blocks low right (with 3,4,5,7,9 below) are for selecting the IRQ of whatever is mentioned in the side (async1, async2, ptr1, ptr2)
The 4 jumpers lower left (JP1-4) are most likely for the address setting of ASYNC1/ASYNC2 normally 2E8/2F8/3E8/3F8 and then the other three jumpers would be for the PTR1/PTR2 address setting 278/378/3BC (JP5 and JP6) and the third one for enabling disabling the game port.
