JANDER is an XP1000, the other two are PWS.

I'm not sure if they are original DEC or not.  68-pin, of course, wide 
ones on the controllers and on the personality module in the BA356s, 
except for MINNIM, which has a VHDCI.  There is only cable between the 
connectors.  (In the past, I tried connecting cables together to get the 
right plugs at both ends, but even if the length was not too much I got 
errors.

Not sure of the exact number and whether they are all the same, but it 
is definitely a 16-bit personality module.

But in that case shouldn't I be seeing many more errors?  Also, I'm 
pretty sure I checked the positions of the jumpers in the boxes before 
filling them up with disks.
