Hi there. First of all thanks for the effort and well done.
I have ordered several of these :http://www.ebay.com/itm/301976968423
Which I believe this applies to standard gotek (not the new flash ones you mentioned recently)
Also I would like to know if your 3D files in this version are compatible with all A500 models as I have seen somewhere that certain models have different floppy eject slot design.
Thanks in advance and keep it up!
