Instead of going with an indivision device for now I decided to use the plain old Video connector.
For this I bought the VGA Converter from Axel81l as unbuffered version (disappointed that no screws are included).
I tested a bit and I found out that the stars basically have to be aligned right:
If I use the Amiga 1200 with a "cheap cable" then I get nothing.
If I use an expensive cable directly with the Retrotink4k I get a proper signal.
If I use a setup with an Extron SW VGA ARS Switch (its a powered switch but set to non-auto), it will not work. (Doesn't matter if the Port in question is currently active or not, the Amiga 1200 will not boot)
If I use a setup using a cheap passive VGA Switch, connect this to the Extron SW VGA ARS Switch, then switch it to a channel with no connection, the Amiga 1200 will boot. Now I can switch it to the right channel (going to the Extron VGA Switch) it will work. But it must be set to a different vga channel when the amiga is booting. So this basically equals to pluggin in the VGA connection only after boot.
This now results in a couple of questions:
1. Will this cause any damage? Like actively switching the VGA connection. Possibly sending some "bad" stuff to the Amiga it cant handle via booting.
2. Why does this happen in the first place? I guess one of the channel is used for communication and the Amiga 1200 only does something if it either gets an "ok" or nothing at all, but wont boot on a "err..dont know"?
3. Is there any way to avoid that? I do want to use that without putting another switch into that switch or something crazy like that. My setup is already wild as it is. Would a different adapter help? E.g. a buffered one?
If you have any other comments which could be helpful, let me know!
