I found this Juko graphics card in my collection:
I found the jumper settings of a similar one here: http://arvutimuuseum.ee/th99/v/I-L/50442.htm
Unfortunately, this one is not the same as my card (mine also has a couple of switches at the top (9 in total) that I have no idea what their function is).
Does someone perhaps have the manual or jumper settings for this particular model?
Just a follow up - I managed to track down the manual for this card.

Thanks for posting the manual for this card!
I just found one of these in a recently-acquired "Logi 88-XT".
Did you ever find the driver diskette for this card? I'm interested in the ability to switch between the MDA mode and CGA emulation [16 shades of grey, such wow!]. Sadly the graphics chipset on this card is one of those weird "UDL" ones which have zero information available.
It has RTC and WINCHESTER, IO ports and VIDEO, but no FLOPPY if i understand it correctly? COM2 UART socket is emty?
I am aroused about any X86 motherboard that has full functional ISA slot. I think i have problem. Not really into that original (Turbo) XT,286,386 and CGA/EGA stuff. So just a DOS nut.

Unfortunately not.
You mentioned that you found one in a PC? Did it have a hard drive? If so, it might be on there?

Sadly the HDD (a Fuji FK309-26 MFM drive hooked up to an Adaptec RLL controller) doesn't spin up when power is applied, so it's going into the "maybe fix it later" bin for now.
I would like to eventually recover data from the drive and see what this Logi 88-XT got up to in its previous life.

Floppy connector is the 34-pin header at the extreme end of the card.
My card also has an empty spot for the second UART chip.
I'm excited to try the CGA emulation (using the jumpers to 'force' that mode) and see how it looks on my MDA monitors. And check how accurate it is: what will 8088 MPH do to the poor thing?
CN10 and CN9 are winchester data connectors, and this means that this ONLY 34pin header IS winchester control port, and not floppy port. Because if there were 2 34pin connectors, then yes you have winchester ST506/ST412 connector, and a floppy connector. they both have the same pin count, but not the same pinout.
Just saying, that be careful inserting a floppy there.

CN9/CN10 are the RS232 serial port headers.
OK. Then they are with some kind of strange pinout. Because usually com ports are only 9 pin connector. like that MOUSE connector in the right upper corner.
