I found this 1503968XM floppy controller card in my collection but wasn't able to find any reference to that number. It appears almost identical to the 6181682 floppy controller except the appearance of RP-1 in the top-right corner (and the fact that 4 chips are now socketed). I don't know how much of an oddity this card is, so I thought I would ask here and find out,
