Up for auction are the complete set of floppy disks for MS Windows OS v.1.0 and MS Windows SDK v.1.0. These were given out at a Microsoft developer's conference in Santa Clara, 1986. During this conference, Steve Ballmer and Charles Simonyi were just two of the speakers extolling the coming revolution of MS Windows.

This software has never been used, however it did not come sealed in envelopes, but was part of a "developer's kit" given to attendees of this conference.

Please ask any questions prior to bidding.
