|  Re: TED is dead? Strange plus/4 failure...
This is only my wild guessing, since I'm not an expert of the subject. Based on the fact that TED pulls down the IRQ line and there's no change I suspect that the CPU either faulty or somehow runs to a 'Crash' opcode. Could you get different ROM ICs from another machine? Or at least reseat the ones in the tested plus/4?
