Dears, Did anyone around had anything with these? Since FDD is commonly not used anymore and since there is still around a lot of equipment using it some fine people come with the idea of building a replacement for FDD that would emulate its functioning while the data would be stored on USB pen drive. It is indeed a good idea: I guess that a mass production of the device should be no more than around 20-50 $ while these units are sold for up to 500 US$ (in Poland up to 500 PLN, which is 4 times less). Where that is used? Very often still, in programmable musical instruments and, first of all, in machines used in industry. I am landed now at the National Center for Nuclear Research near Warsaw, Poland. And I was given such a toy, a FDD/USB emulator (EMUF-720F), for installing it in Robofill 200 machine which is used for wire-cutting metal. I am fine with that. After some Internet searching I know already, mostly, how to use it. With one exception: I do not know how to boot the machine from that emulator. Help is to be sincerely appreciated. zb. -- Zbigniew KozioĊ http://nanophysics.pl mobile: +48 507 330 216
