Ok, just 2 let you know, 'cause this is beyond explanation. As I said earlier, I was gonna try the Zydec board on my second Amiga (was waiting for an internal FDD which it lacked to arrive) with no KS switcher (rom sharer) board, with a plain, standalone KS 1.3, so i did. And the board works !! (wait, let me add a few more of these !!!!!!) WB 1.3 was succesfully loaded reporting 1935776 free memory. GOD DAMN IT ! It works on my 2nd, nickoteen yellow Amiga and it won't work on my 1st, heavenly white one ! But ... hope is not lost. Just wanted to tell you, there's no need for any addmem or utilites alike. The board is fully functional as is. It just needs to be plugged in.

Are you using the same power suppy?

Other than that, it could be anything. You could try swapping chips.

I'd probably swap the cases, so the one that works is in the nice case.

Yes, I'm using the same psu. I just disconnected my 1st Amiga and connected the 2nd one. The only difference between the two is that in the 1st one I'm using the ks switcher board and in the 2nd one I'm not. Other than that, the Amigas are exactly the same (well, they differ in colour offcourse ).
