Mega ST and exxos Decoder + dual tos problem

[gwinter38]

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.

I have done it here.

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 ?

I would suggest you do all the mandatory fixes to your mega. https://www.exxosforum.co.uk/forum/viewt ... =17&t=1585

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 ...
