No, there's no QBus involved here. The M7452 "UNIBUS Window Module"
connects the VS100 to the VAX via a fiber-optic link.
(DEC did make a Unibus to Qbus adapter, the DW11-B, but it was unrelated to
the VS100)

How the hell did I miss *that*? Cool beans
device, I've never heard of a
VS100. Was it in a Rainbow sized box or a Pro/350 box?
If old memories serve, you'd also need the Unibus-to-Qbus converter. I
recall a discussion between someone from, I think DEC UK Reading, asking
about a DEC Unibus-to-Qbus converteer. The other person said DEC didn't
have such a device. then Vaxstation-100 was mentinoed. I expect you could
get it to work as a Qbus device with 18-bit addresssing.
