It was a hybrid port in that many of the low-level operations were passed on to QuickDraw instead of using the internal bitmap code. The application did not conform to the Macintosh user interface guidelines as it took over the entire screen. The initial version used either available serial port as the communications channel. A later update of the port could use either ethernet or serial communications. [No reference to how this was obtained] MGR reference manual (from Stephen A. Uhler's home page): https://sau.homeip.net/papers/mgrman.pdf Architecture and Design of the MGR Window System: https://sau.homeip.net/papers/arch.pdf Here it says a port to Macintosh-Plus was done in two weeks.
