FYI - they posted a PDF on the website selling the floppy drive adapter.

After reading though it, it seems it will be compatible with the Haas. A few notes:
1. A usb drive or a folder on a usb drive can be "mapped" to the floppy drive adapter.
2. The total size of the files in the mapping cannot exceed 1.44mb
3. The network port on the adapter is actually a RS485 port, not ethernet.
4. There is a delay between read and write that could cause an error in the host machine.
Because the size of the files in the mapping must not exceed the size of files that can fit on a floppy, I'm fairly confident that this will be compatible with the Haas controller. I was expecting to be able to load files larger than 1.44mb (3d toolpaths can get quite large).
I asked them if they would send me a sample or discounted test item, but no response. I don't think its worth $300 for me to discard my usb floppy just yet. In fact, I usually transfer files and DNC wirelessly via my ConnectBlue bluetooth to RS232 adapter I purchased on ebay for $50.
