Hmmmm... I am at this moment using a Leading Edge model 
D with  a direct serial line running at 9600 baud, with
a Sytek box at the other end and I don't have any trouble
when the switch on the back is set at 4.77 MHz. If your
screen scrolls too slowly, try running something like 
FansiConsole to speed it up (I do).
