CoreNET software PC-51 for IBM 5100/5150
There are references to a very old piece of software called PC51 from CoreNET - that allowed some cross-communication between the IBM 5100 and IBM 5150. But I can't find any reference to a manual or the media. The media may have been on a cassette tape (for both platforms), and no idea how the interconnection was made. But if anyone knows of a place repository where this might still exist, would be interested to learn more about it.
