Floppy Emulator

There is now support for FLEX and  OS9 with the GoTek floppy emulator with flash floppy firmware update,  The GoTek uses USB sticks to store floppy images and could contain thousands of floppy images on a single USB stick. This allows users to download DSK image files from the FLEX users group and with a newly released utility convert these image files to  .IMA format used by the modified GoTek unit.  The firmware is free and the software to reflash the GoTek is also free.  You will however need a USB to TTL serial cable and a PC to reflash the firmware in the GoTek.  Once modified, future firmware upgrades can be installed from a USB stick.  For those not wishing to modify the GoTek, we will provide modified GoTek's ready to use, but these will be ordered and modified after your order and of course are not warranted since reflashing the firmware on the GoTek will void it's warranty. You should consider the OLED modification mandatory, since it is almost impossible to tell which image file you have selected without it.

The instructions for flashing the firmware and adding the OLED can be found here -
