I used a Toshiba 4030CDT as a test platform for the floppy drive simulator which is available from my website:
http://amiga.krishnasoft.com.
I started this project when my floppy disks getting read/write errors. Now I can boot up the ADFs directly from my Toshiba laptop. It's currently works in read-only mode and for all parallel ports capable of 1 megabyte/second throughput.
I previously did this for Atari disk drives which were much simpler to deal with and did not require a fast throughput so the read and write modes both work.
For desktops, you can easily get a PCI parallel port that does 1 megabyte/second so I can use the same machine for simulating both Atari disk drives and Amiga disk drives.
Now I have a whole bunch of amiga image disks on my Toshiba laptop and I can boot from any of them or make them come up as an external disk (DF1..DF3).
