Classic Mac software for the Mac Plus uses the vertical flyback interval of the 
cathode ray tube display for a lot of things. It's an interrupt that makes a 
whole lot of things happen, mouse, keyboard and other goodies.  If you want the 
original motherboard and OS you'll have  to simulate that or rewrite some 
software.

The "video" from the Plus is nothing like interlaced NTSC video for a 
now-deprecated TV set.
