In an effort to understand more about the TF 1230, what method does this accelerator design use to take over control from the A1200's
on-board 68ec020 processor? Companion question: is control permanent until system is reset?
Thanks so much

Re: TF 1230 boot method?
There is an 030 enabled jumper. the clue is there. When one CPU is active the other is disabled.

Thanks so much for that clue - a 030 enable jumper - just what I needed.
Also just found a document on github.com with many details:
Search for: "https://github.com/lvd2/A1200_trapdoor_docs"
The folder: ext_docs contains the kind of document that was hard to find, hope it is helpful to others
who are looking for how-things-work on the A1200 and expansion cards for the 150-pin trapdoor.
