This is a file-sharing utility software planned and sold by Yano Denki Co., Ltd. that allowed file sharing between Macintosh and Windows. It was for older Macintoshes, and was a utility software that allowed easy network construction between Mac and Windows. "WIN MOUNTER" is a utility software that connects two or more Macintosh & Windows machines to easily share files. File sharing between Macintosh and Windows was possible with simple settings. It allowed access from Macintosh to shared folders and drives on Windows machines, enabling file copying and moving. Operating environment: Macintosh (68020 or higher, PowerPC equipped, KanjiTalk 7.5 or later), PC/AT compatible machines with Windows 98/95/NT 4.0. Currently discontinued and no longer supported. I purchased this used over 15 years ago to build a network with a mix of OldMac machines and Windows machines. I am selling it because I have lost my entire OldMac environment. As a bonus, I will include a complete set of Ver. 3.0 version-up software. I doubt its practicality now, but I think it's something you can't get again, so please take it if you need it. The outer box has minor tears and scratches due to aging. Please purchase only if you agree with the above. Immediate purchase is OK. Thank you for viewing.
