Honeywell 440

Jim and Sherman (?), I checked and I don't have anything on the Honeywell 440 or anything like a re-branded Honeywell sold by GE. I think that the name "General Electric" printed on the back was due to the fact that they owned the Honeywell 440 and used it internally. It's not a GE PAC or

OK. I must be missing something here Does anyone have a M7800 (DL11) set for 9600 b N71 or N81 jumper'd with the default address for use as a serial terminal interface? I understand the other jumpers on the card, but the address and vector jumpers confuse me. I can't seem to find a table or a
