ADTPro transfers disks to and from Apple II and Apple /// computers and the modern world using any of these communications methods: serial/USB, UDP via the Uthernet or LANceGS Ethernet cards, or audio via the Apple's cassette ports. ADTPro has comprehensive bootstrapping support for otherwise diskless Apple IIs. The home page includes extensive tutorials for getting started.
GSport is an Apple IIgs emulator based on Kent Dickey's excellent KEGS emulator. It features updated support for the Uthernet Ethernet board, as well as virtual printer support. Code from several KEGS variants over the years was merged together to form this codebase. GSport's name comes from the merging of "GS" (as in the Apple IIgs) and portability - in the programming sense - since it can be built and run on many different computer platforms.
