What to expect with a 9406-170?

Hello all,

First off, I'd like to say that this group seems like a great bunch of smart folks; I've been watching the list for a while now and would like to say thanks for all the handy information that I've gotten already. I'm almost somewhat embarrassed to ask for assistance here with such an old machine, as well as being very new to these systems as well. I suppose you could say I'm a hobbyist, however I am hoping to learn what I can and hopefully take that to a job someday.

I found an old 9406-170 locally and have been collecting what I need to access the machine at home. I'm waiting for some baluns to finally connect my 3476 terminal to the machine to see what it's complaining about.

Currently, when power is applied, the code displayed on the panel seems to tell me that the battery has died. I don't recall the code at the moment. Powering on the system takes a few moments with many codes displayed, but it finally settles on 675a3200, with no processor activity, and the attention light on. I believe this code relates to a disk failure; but I'm curious; if no O/S is found, will it display the same code? Will the system battery being dead cause IPL issues?

Many thanks in advance,
Clay Carley
