Version 0.65 of the Visopsys operating system was released today. A lot of work has been done on the USB subsystem and underlying UHCI driver - though it's still not 'there' yet it has been re-enabled for the time being. New features were added to the Disk Manager (a.k.a. Partition Logic) including partition copy/paste (same disk or disk-to-disk). And finally, as with the last few releases there's been a focus on improving the GUI code. You can demo Visopsys on a floppy or live CD. Downloads and change log.
