I was wandering around the internet and found a site in Germany where an 
Atari ST in FPGA is under development. One of the IP cores completed and 
tested with MFM floppies is a WD 1772. With a minor changes this could be 
a WD1773 or a s uper 1773 that could interface to HD floppies if one were 
so inclined.

is the link to the rtl files. Under Suska go to Configureware/2k7a/archives/ 
and either zip or targz and download rtl.*
