I'm running into issues with hard-coding some devices (see recent post 
titled 'device.hints isn't setting what I want').

Associated with this issue is confusion over whether I want to use ch0 
or pass1.  I have these devices:

<DEC TL800    (C) DEC 0326>        at scbus1 target 0 lun 0 (ch0,pass1)
<DEC TZ89     (C) DEC 1837>        at scbus1 target 5 lun 0 (sa1,pass2)

My understanding: chio(1) will with ch0, whereas mtx(1) will work with 
pass1.  Is this correct?  More information/elaboration will help I'm sure.

Why do I ask? I can get the tape changer and tape drive hardwired to ch0 
and sa1 respectively.  I cannot [yet] do the same with pass1.

Thanks folks.
