From the project

Floppy disk emulator for old computers and machines, Amiga, Atari ST, etc.

Emulátor disketové mechaniky starých počítačů a různých zařízení. Software se do počítače nahrává z obrazu originálního disku (např. ADF pro Amigu), který je uložen na USB flash disku. Tato verze hardwaru využívá firmware FlashFloppy, který přidává spoustu nových funkcí a vylepšení oproti standardnímu Goteku. Na uvedém odkazu tvůrce, najdete detailní popisy všech funkcí a nastavení a také nejnovější firmware.
