DEC M9312 Configs for a 11/40

I can take some pictures of the M9312 I have running in my 11/40 tonight if need be. The manual at http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/unibus/M9312_TechRef.p… (page A-2) suggests that W8 should be IN. Can you describe how your system is configured (i.e. what's on the bus, what's in the CPU, etc?). Have you double-checked that the interrupt vectors for your SLUs are correctly configured? The console (and BASIC, IIRC) does not use interrupts for serial I/O and will work if the vector is misconfigured (I discovered this the hard way in my 11/05) but other things will not and will behave badly. I'd also suggest using PDP11GUI to load in diagnostics directly, this avoids needing to be able to boot XXDP... - Josh On Sat, Nov 26, 2016 at 9:58 AM, william degnan <billdegnan at gmail.com> wrote:
