Hello,

    I agree that some emulators like AppleWin do not do flash feature 
correctly in 80-column.  KEGS has flash feature in 80-column, but it has 
wrong flash counter (such as speed of inverse/normal switch in 40/80 
column).
    Some programmers are doing their best job to write emulator projects, 
but they lack understanding or acknowledge of Apple II hardware and design. 
It is why I have to emulate hardware by following the logic process rather 
than to have some guesses without knowledge of hardware.  I would make any 
correction on some emulator projects for some times.
