It was news to me too! (And apparently to most others here too?) I was going to look at those confusing bus cycles, using an only slightly mis-addressed console, and wanted to first check that that console worked when properly configured; so I plugged in it and an LSI-11/2 CPU - nothing. Switched to a different CPU (maybe the first one died), _still_ nothing? So I tried an -11/23, ODT worked! So, the console worked; the chances of two CPUs that were working a week ago suddenly both dying seemed slim... what else could it be? And the /23 works with no memory! Odd. Will definitely have to make a note of that LSI-11 behaviour on the CHWiki. > I plugged in my 32kw module with my M8017-AA, and it fired right up to > ODT without a hassle. Yee-hah!!! EXCELLENT!!! Well, it took a while, but we finally got there! Do let us know how it goes with your next steps - and if you have an issue, let us know! (Hopefully, next time, we won'tbe so clueless! :-) Noel PS: Might be useful to check that the DLV11-J works; having a stock of known-good boards you can swap in is such a tool for QBUS debugging.
