What won't a Sun 4/110 VME do?

[Chris Brown]

Some while ago my Sun salesperson told me that there was some way in which
the VME bus on a Sun 4/110 was not a complete implementation  -- something
to do with not having a bus arbiter, I believe.  I didn't take much notice
at the time because it didn't matter, but now it does!  Can anyone tell me
*exactly* what it is that the VME bus on a 4/110 won't do?

Also if anyone has experience of connecting a 4/110 to an external VME
rack using a VME/VME adaptor, I'd be interested to hear from you.
