KY11 - ever debug one?

I could swear there was a discussion recently (like in the last week) about 11/34 consoles and KY11 documentation. Or maybe I dreamed that up. Anyway, it prompted me to try and figure out why my 11/34 console was blank. The serial monitor works fine, as does the cpu, but the "digits" in front are blank and only the run and dc-ok lights are on. (this is a symptom described in the ky11 documenation - thank you very much to whomever scanned that in) Has anyone debugged a dead KY11 ? Any hints? I looked at the docs and schematics and followed the wise words on page 8-2 titles "M7859 FAILURES" I have +5 and -9 on the 8008 as well as clock(s). But the "INTR" line (pin 18) is stuck high. I assume this is the problem. [aside - I plugged one of the cables (J3) in backward and got the display to show all zeros', but the scan rate was *very* slow, light 10hz; I found that interesting] STOP L and TS1 L are inactive, as are all the S0,S1 & S2 on the 8008. Interestingly ping 14 is wiggling. I don't have a databook with with an 8008 in it and that pin is not labeled. I have only just started, but I'd thought I'd ask if anyone has done this recently. It's fun debugging ttl. It's all so *slow* and manageable ;-) -brad
