Unfortunately the data sheets for that series say that said chips come

Last time that I tried to research it, I found

some spoilsport has removed the numbers from them. One (14 pins)
is probably a TTL buffer to drive the disk drive signals. The other

of the other chip) is presumably a USB floppy controller. When I have
time I'll probe things and see if I can figure it out.
