I use a STM32F4 MCU for my floppy work (and my tape work also). Half a meg of program flash and 192KB of SRAM on-chip, running at 168MHz. But my interface is strictly by image file. The USB connection is strictly for file transfer and terminal operation. One does a whole disk at a time, since the bulk storage interface is SD Card. Currently, I'm limited to 32GB there. I'm interested in recovering data, not running games. --Chuck
