No, the host system needs a USB connection--probably at least 2.0, but I haven't verified that. (I did build one and even added a stage of output buffering). My STM32F407 solution has proper buffers and termination between the drive and MCU, and records all data on an microSD drive, which can be uploaded or read directly. Comms is via USB or UART, depending on compilation option, so it can be used with a dumb terminal or a legacy S100 system capable of serial communication. The nice thing about the 407 is that it has a much higher clock rate, meaning finer sampling and 512KB of program flash along with 192KB of SRAM, so a whole track can be held in memory. I should probably mention the floppy reader I built years ago using a ATMega162 and 128K SRAM. It could also emulate floppies. For whatever it's worth. Chuck
