Hi all,


I didn't have time to follow the community for a long time, but I refer speaking with someone about the idea of Switcher board that would allow you to boot Amiga either from stock 68k or TF board. Is it possible?

Thanks and stay safe

Mine was for the ST, but without the ROM logic should work equally well in the Amiga, assuming the space is correct.

I can send to you the full KiCad files so that you can design a simplified version for the Amiga.

This is perhaps getting a bit too far from the original source. @stephen_usher's board is based on my board, which is based on an Amiga board called "garlic". Might be best for @bartekmalysz to go all the way back to the original, which came from a1k.org. Looks like maybe a login is required to read the thread over there, but 8 Bit Dreams posted a link to the garlic schematics over here. In fact, that whole thread is probably worth a read.

I ended up having to switch a bit more to make the Atari happy, but apparently the simpler garlic setup is fine for Amigas.

@derkom the O.P. has been in contact with me. He doesn't have soldering skills at all so would need someone else to build the board for his CD32.

CDTV to be precise, and yes, I'm on the edge when it comes to space there:

CDTV with TF536 and SD2IDE it also uses Go0se's relocator for CDTV
