  format a:
does an endless loop.

Edit: oh, going back I got an JS popup:

  Unable to restore disk 'PC-DOS 2.00 (Disk 1): 
  sector (CHS=0:1:0) out of range (9 changes applied)
After pressing the reset button:

  Non-System disk or disk error
  Replace and strike any key when ready
I had to press load disk A button, to start fresh. Quite impressive.

And then I just found out to load Windows 1 with mouse support. Wow. Made my day. Epic!

It's a major point to make sure errors are properly emulated as well. Same issue was dealt with in VMware Workstation as well, which managed to behave accurately for devices such as floppy disks.
