Hmmm... you for shure won't be able to use busy-flag checking. But 
without, at may work.

Maybe there's a problem of too much electrical load on the parport with 
two displays in parallel. I can't tell, you'd have to try this.

But I could think of another idea: if the two displays have only one 
controller each (and therefore only one ENABLE line), you could use tham 
as one bit display by using "Controllers 2" and "Wire.ENABLE2 
<anything>". Just use different lines for the enable signals.

This way It would be even possible to display different things on both 
displays.


bye, Michael

btw, if you succeed, could you please describe this geek idea in the 
wiki? Thanks!
