That is exactly what I mean. Maybe someone has a circuit of how to change these TOS jumpers? I burned 2 eprom's with Tos 206 and made adapter for 28 pin. Unfortunately they do not work, probably because of the jumpers.

It is a strange thing. After inserting ct'ide + tos 2.06 , the mega st works properly, boots from a floppy disk and ultrasatan. Also TF536 works (does not showing altram).... @exxos could be a problem with Your decoder ?

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Okay , I burned the eprom tos 2.06 , I put the decoder in 520St and it looks like the computer is working. So probably the problem is my MegaST. Thanks for Your help @exxos , I'm getting to do the fixes ...
