Hi grobi,
Didn't you want the switcher for a CDTV?
In the first post, you'll find a link to an Installation manual in PDF.
For the Amiga 600, the wire must be soldered on one pad of R951B which is near PAULA IC.
There is the explanation of exactly where to solder the wire used to pick up the RESET signal and a picture to help you.
The ACA620 is plugged onto the 68000 and doesn't cover the Kickstart ROM socket. So, you have just to plug the socket of the switcher into the ROM socket of the A600 motherboard.
There is enough place to put the switcher near the back of the Amiga.
Best regards,
Franck
