Re: Get info when QL is ready with screen redrawing?

Maybe to state it clearly and I need your opinion if the whole story is possible. I wrote some demos for Amiga in 90' but the QL... I'm just in love in this machine. My plan is to write a simple scroller (as I did for Amiga) but using just pure QL (68008) with 640k memory. Possible, without flickeri...

Re: Get info when QL is ready with screen redrawing?

Another method, which is horribly inefficient, is, synchronize your screen updates with the 50Hz interrupt (polling interrupt) Tobias Wow, many thanks for your ideas. The 50Hz interrupt (7) was also my idea but this interrupt I just want to use to play "music" in background. So switching ...

Switch off Pointer Toolkit

I just got completely new "Sinclair QL Tetroid disk interface with Compact flash card" and setup my QL. However it always starts with the Pointer Toolkit. How can I switch it off and go back to my plain vanilla command line?

Re: Get info when QL is ready with screen redrawing?

It's also an option to turn the video display off while the screen is being redrawn, so the redraw happens during the dark spell, if that is the effect you're trying to achieve? Yes, exactly. I know it from Amiga where you can query if the redrawing of the screen is ready, allowing making some chan...

Get info when QL is ready with screen redrawing?

Is there any possibility to get an info that QL is ready with redrawing of the screen so I can update the screen memory (using some cycles) without the effect of flickering?
