What's preventing me from trying that out (at the moment) is cabling.

I think I know what the problem is: I'm using an internal 68-pin cable 
with an active negation terminator crimped on the end - so far, so good. 
However, the 68-to-50 pin adapter I'm using (apparently) is terminating 
the high bits, so the high bits are terminated twice.

I'd like to try it on a narrow-only bus (like the VAXstation's) but I 
don't have any way to terminate the bus.

The manual recommends attaching a pass-through (inline) terminator on 
the DDS3 when the DDS3 is the last device on the bus. I don't understand 
how an inline terminator can work when it is before the device (I 
thought the terminator had to be physically at the end of the bus), but 
I guess it's wired that way internally.

I found a supplier for such an inline terminator, so it's just a matter 
of ordering it and shelling out the dough.

Another idea I had was to buy a cheap narrow drive and put that on the 
bus after the DDS3. That way the VAXstation could have its own disk 
instead of being a satellite (which raises all kinds of configuration 
issues I'm not ready for yet - see my other message).
