I do believe, that the first card is a Floppy Controller named : Universal Driver Controller (aka UDC) typically build by VTech
Second card (just my thoughts) could be a switchable ROM card... while I'm not sure what the content of the ROMs could be.
Thanks. Yes, I found a post about - it should be possible to connect 5 1/2 and 3 1/2.
Maybe someone knows more about the second card?
The second one is a card from the company later known as "memsoft"
You can find some of their cards here: http://mirrors.apple2.org.za/Apple%20II%20Documentation%20Project/Interface%20Cards/Other/MEMSOFT%20MEMDOS/Photos/
I'd guess that Antoine Vignau might be able to identify that card.
You will find detail information on Memsoft products on Antoine's web site.
