I have a couple of mega128 boards here, and I cant read their sig using AS4 and a JTAGMKII or AS7 and a JTAGICE3. I can see the TDI only goes down from 5V to 3V for an instant when reading the sig. I guess I'll have our expert suface mount technician swap 128s tomorrow, unless someone can update the tricks n tips n things to try list here. I don't need a legacy device pack to program an old 128? Standing by.
