Notes

FlashFloppy

FlashFloppy is a floppy-drive emulator firmware for the ubiquitous Gotek hardware. FlashFloppy is directly compatible with most Gotek devices with a 34-pin header. all of which share the SFR model prefix (eg SFR1M44-U100K, SFRM72-U100).

Configuration

IBM PC compatibles have a non-Shugart interface which must be explicitly configured in FlashFloppy:

  • IBM-PC interface mode must be configured
    • Strap jumper JC at the rear of the Gotek; or
    • Specify via FF.CFG: interface = ibmpc
  • Strap select-line jumper S1 at the rear of the Gotek
    • S0, S2, MO should all be left open

Gotek Models

Gotek SFRKC30.AT4.35 (AT32F435)

Gotek SFRKC30.AT3 (AT32F415)

SFRKC30AT3 (LQFP48): Missing the original rotary-encoder header, but features the new KC30 rotary header.

Gotek SFRKC30.AT2 (AT32F415)

SFRKC30.AT2 (QFN32): Missing the original rotary-encoder header, but features the new KC30 rotary header. The first revision of this board is also missing the JC jumper location: PC interface mode can be specified only via FF.CFG.
