Hello. Last year I picked up a brand new Magitronic PC/XT system on eBay. About a month ago I finally got around to tinkering with it.
The original full length FDC, dual COM, LPT, Game, and RTC card has extensive Varta battery damage but still works. It's this card:

I'll need to replace and repair many of the components on the card. In the mean time I picked up this I/O card on eBay:
https://www.ebay.com/itm/NEW-8-Bit-...-XT-PC/233934700478?ssPageName=STRK:MEBIDX:IT
My question: Does anyone have the correct documentation for this card? The seller's pictures of documentation are incorrect. The only markings on the card that help in identification are JCC and IOS-2. The card appears to be a variant of these two cards I found:

If you would like to read further here is the problem(s) I am facing:
This is the motherboard (sorry could only find a pdf):

I removed the original Magitronic MGA/parallel video card and installed an 8bit Oak VGA card:

I removed the original ST412 MFM controller and 10MB ST412 full height HDD and installed a lo-tech XTIDE attached to a CF card reader:

I installed an 8bit Media Vision Thunderboard:

Everything works just fine with this setup and the original FDC I/O controller installed. When I replaced the I/O controller with the one I purchased on eBay the CF card failed to boot, "Missing Operating System". I pulled the Lo-Tech XTIDE card and then the new FDC card came up with a menu asking to identify the drives attached. I set the card up for two 360KB 5¼" drives. Putting the Lo-Tech back in yields the same results as before, "Missing Operating System"
Pulling the lo-tech XTIDE back out I realized the new I/O card will not boot from floppy either. The A: drive clicks a few times and then "Non system disk or disk error, replace and press enter to try again". I tried playing the binary shuffle with the jumpers on the I/O card but more often than not was greeted with 601 errors on system startup.
The seller is sending me another card to eliminate the possibility of a bad card. Any ideas/suggestions at this point would be greatly appreciated.
