From scratch, I'd pefer the 2793.
There is another option, get a FDC card from an
old XT level PC. I did this for may NC4000 machine.
It is not anything like a x86 machine.
Of course, I could only do 360K disk without modifications
to the clock speeds. I don't recall which chip it used
but it seem like I remember it being one of the 179X parts.
I did all the interface as direct CPU controlled without
DMA but then, the NC4000 is one fast processor.
