its a mix out of a big old analog switch and some LSD

sometimes you will see colors and other cool effects  :D



...
the switch is electronic, it needs a signal (low/high) to select one of the both sources
the second part is "switchcontrol", this tool detects every change of the monitorid/screenmode
switchcontrol is providing the electronic with the correct low or high signal, depending on the used screenmode
signal will be given by the 8520-ic

Ahh ok, so the tool monitors the screenmode and sends the signal through the parallel/serial port to the hardware to tell it to switch. Is that right? How does it work with system unfriendly software which turns off the OS?

Just like every other amiga graphiccard (with inbuild switch like cv64, piv, .. ).
There is no difference.

If you use heavy unfriendly software on a rtg-system you can notice sound, but sometimes you can still see your frozen workbenchscreen (rtg).
This is on cv64, piv and all gfxcards with inbuild switches the same effect.

Add a tool like RunAGA to c: and the tooltypes of this demo.
It helps a lot ... (the tool is opening a pal-screen before executing the code).

But if the OS gets switched off, e.g. by WHDLoad, how is your tool able to monitor the screen mode changes?

WHDLoad opens a ECS/AGA screen by OS-functions before giving control to the "game".
Same with demos that uses the example standard demo startup-code (from how to code 7).

If you want to feel better ... I had the chance to talk with Frank Mariak (CGFX) about my solution.
And it turns out, that i used the same way like CGFX did it internaly. SwitchControl is "snooping" the same functions and tables.

Great stuff - sounds like an awesome solution. I assume that quitting WHDLoad triggers a standard OS function when the RTG screen mode returns?

With quiting, WHDLoad switch back to Workbench (depending on your setting, this could be RTG).

Did they give a reason as to why they were not interested?

Odd that the dealers won't produce them, as they are a great addon to a graphics cards without a build in monitor switcher.

Does this mean that if one was in the need of one or two of these switchers, they have to live without or take up one of the DIY jobs?
