I know this  is a long shot but does anybody know anything about 86Box? Someone asked me to  see if my RPItalk hardware synth (a LiteTalk/DECtalk  emulator made  from a Raspberry Pi) would work with Jaws for DOS. But apparently,  Jaws for DOS needs  an old AT keyboard. A USB or even a PS/2 keyboard doesn't work. So I found this virtualization package, 86Box that supports very old hardware. But I cannot get the GUI interface to work with Orca. Specifically, I cannot configure a 3.5" floppy  so I cannot install FreeDOS. The interface  is simply not lettimg me change the default configuration of dual 5.225" floppies. Nothing I click on does anything. I can  change everything else -- mobo, RAM, serial ports, etc. Just not the  floppy  drives.
