Terryc,
make sure you unzipped the downloaded file to your hard disk, then ran the executable [pa80_305.exe] to create 5 - yes FIVE !! -floppies.....

PS: A great source of PA80 inof is available at the 'unofficial' Korg Suport site http://www.irishacts.com or thru the Yahoo groups http://groups.yahoo.com/group/KorgPA80 and http://groups.yahoo.com/group/don48splace

You'll need membership to get access to any of them.

PS: Latest PA80 OS - unless I've been sleeping lately - is 3.05 !!

Hope this helped..
Regards,
Steve
