TOS for STF with 2 chips

[exxos]

But did you change the CE SELECT to AUX ?

Sorry, I understood that AUX was for boosters.
Modification done, and something is happening. The decoder now turns on even with BK2. I see this, and I don't know what it means

and after that the decoder's LED turns off

It normally means the floppy drive is not connected. Standard for TOS206 to do that.

Great, the bombs scared me. I must have a gotek. I will try to figure out how to make it work on the STF.
So I assume that all is fine now.
Thank you SO MUCH for your precious help.
