I've got a board that plugs into a 5150 (as a display adapter) and 
takes the MDA display and combines it with  RS-232 data coming in 
from an external system and formats the display as split-screen on a 
VT220 terminal (the board also plugs into the 5150's keyboard port).  
There's no software that comes with the board--all of the smarts are 
on the board in the form of a Z80 sharing display RAM with the 5150.  

Were there any good reason any of the coprocessor boards for the 
Apple ][ couldn't have been time-sliced with the main 6502?

Cheers,
