     The Perkin-Elmer 68K boxes use VersaBUS.  The NCR Tower uses MultiBUS.
Many boxes have no bus at all or vestigial buses (low end Alpha Micro).
The New Frank Hogg QT-20X has a proprietary bus.  The SS-50 bus is used
by GIMIX.  The SS-64 bus was used by Helix.  I think Altos uses something
different, but I'm not sure what.

     Your close enough though.  Most good 68K boxes are VME.  Still, I'm
buying the Frank Hogg QT-20X.  The prices is *much* better.

I love when somebody makes a blanket statement like this :-)

Masscomp uses the multibus in their 68010 machines.  I think they also use 
it in their 68020 machines.  

Note: I'm not saying it's a good or a bad idea, 
      I just be relaten da facts, jack.

	I think most people know that we do a lot of 68XXX ports .... I would
make a rough guess that about half of the boxes we see these days are VMEbus,
(this is definitely an increasing trend) most of the rest are spread amoung
(in no particular order) multibus, S100 (yes there are still some of them out
there!), UniBus and proprietary buses (still quite common)

Who (or what organization) should I contact in order to obtain A VMEbus

The NCR Tower family (Tower 1632, Tower XP, MiniTower, MiniTower 32,
Tower 32) all use Motorola processors with Multibus I.

So do I - a single Spectrix XL machine has the following "buses": Multibus, 
Intel iLBX (actually, Multibus P2 connector), X-Bus (extension of 68020
pins), MX-bus (ribbon-cable), Intel iSBX bus and the FIFO.  Not a VMEbus in
the lot! :-)

They actually use Multibus II in the '010 machines, and a slightly
modified (?, maybe just more careful part selection and shorter
cabling) version in the '020 units, to bump the bus speed up to ~30mhz.

Most Sun 2's, I think, are still Multibus, as were the Callans and
countless other Unix boxen.  Strange how they ended up with
Intel-derived things, isn't it...

	And Masscomp is currently working on a VMEbus machine...all their newer
machines will be VMEbus...that is when they get it all working, including
a VME to Multibus card.

	In fact there are several 68000 machines on the Multibus because it
was out there and controlers were available before the VMEbus was accepted
here (it was originally called the Eurobus with some differences).
