I was considering a Gotek emulator for the PWC8256 board (it has 512K RAM).
But I have Chrome Book converted to Linux and ran Joyce emulator on WINE. Except it only read / write the disc image it's booted with. I'll try the native Linux version of Joyce later.
I can only read/write MS DOS discs with the USB floppy drive. To read other formats I need my last working PC (which has Linux) with a real floppy port on the MoBo.
