+The BA-11N expansion chassis arrived today. Managed to scrape my left thigh
+getting it out of the box, no permanent harm done. As promised, it looks
+brand newish. Figured out how to get the cover off, then powered it up with
+no cards and all looked ok. The +12V supply was more like +10V, but with no
+load it's hard to know what to really expect.
+
+Drilled out the rivets holding the s-box front panel hardware to the KDJ11
+board, and put it into the top slot. Extracted the little front panel board
+from the s-box hardware, snarfed an MMJ serial cable from the vax, and the
+board came up! Hitting ctrl/c on the console after the LED display started
+alternating between E and F gave me a console monitor interface. 9600N81

+So... once we have an ethernet card, it might be possible to bootload something
+using mopd into RAM? To what end?
+
+The backplane in this chassis should be set for 18-bit addresses. Will need
+to tear the chassis apart to get the backplane out and add jumpers to connect
+the other 4 address bits since the CPU should be emitting 22-bit addresses.
