At least knowing what to expect (off or on) is what's important. As I said, the 11/04 has specific wire jumper settings. Such as W8. These must be correct for the CPU, the UNIBUS must be in a non DC LO AC LO, etc. I went through all this with my 11/40 (not 04) and it was a great way to learn about and diagnose the machine function. b
