This is an OS/9 X68000 40MB SASI hard disk image configured with the PWIN window system. It is known to run under XM6 (http://www.jcec.co.uk/X68emu.htm or http://yohkai.no-ip.info/x680x0/XM6.htm) as well as WinX68KHighSpeed (however, the floppy does not work under WinX68K). The C compiler as well as a few other applications are installed. Most of the system messages are in Japanese by default (the Japanese prompt displayed at startup is a login prompt; to log in as the super-user, press enter). The shell command "unsetenv COUNTRY" switches most of the system messages to English.
