Thank you.

Well, after I realized that the battery of the "CPU board" is dead, I tried to remove the CPU card. This was a small disaster, because I have to figure out how to dismantle the rest before I can pull the card itself. But I survived, so here is a picture of that 386SX ISA-Bus card, plugged in my Siemens PCD-2:


I have no clue what function that switch on right has. It is NOT a switch for CPU frequency (already test with LANDMARK Speedtest).
The card is not a typical industrial CPU card, because almost all of these cards are smaller/not full sized cards. May be someone knows the manufacturer of this card ?

Added later: I have also open questions about this Multi-I/O Floppy + IDE controller card, an Acer controller chip is visible...

I've figured out 4 of 7 jumper easily (located on the right side), enabling/disabling Parallel- and Serial interface. One of the more left located jumper is for Floppy enable/disable.
But two of them are a mystery for me. It seems the outer most left jumper disables the Game Port, but if I choose the lower position for this jumper, Floppy LED is always on, regardless of the fact, that Game Port is also disabled. Very strange...

Added again later:
It looks like this one: http://museum.ttrk.ee/th99/c/U-Z/20337.htm
That means, NO Game-Port DISABLING is possible :-(
