Some precisions since I get some questions by PM (don't be shy, share your questions here so everyone can get the answers!)
There is no software available for this board currentlyWhat you buy is only the hardware. You will have to write your own drivers for it or wait for someone to provide support (as a tool loadable from disk, a ROM, etc). While I have started some work on a ROM, I make no promises or guarantee that I will get that to work, and if I do, when it will be made available.
What will be possible with appropriate softwareSome people will want to use it to load games from it. Remember that it is not a floppy emulator. This means, anything accessing the floppy disk without going through the AMSDOS system ROM, will not load.
Anything that uses AMSDOS, but initializes only ROM 7 or ignores the current drive setting, will not work.
The ROM will also use some memory for itself, which can also create some issues. It's possible to keep the RAM use quite low, but still some bytes will be used at least to store the new RSXs from the ROM.
BASIC programs should not be a problem, more complex software may need some patching. To get an idea, the games with 1 or 2 blue dots listed here will most likely work:

What will be possible without a ROMIf you don't have a ROM expansion already (RamCard, Rom Board, MegaFlash, FlashGordon, X-Mem or similar), this board can still be used with software running in RAM. In that case, the software must be loaded from disk or tape - no autoboot support! The software will of course use some memory for itself, which possibly means even more compatibility problems if you want to use it as a game loader.
I don't plan to provide this kind of software, at all - because I don't need it myself. If someone else decides to attempt it, I can provide support, hints and technical documentation (writing the programming docs and examples is higher on my TODO list than writing the software).
