I agree, that's why I tipped toed through that mine field and said "Most
VAX are mini's". I think the medium sized VAX's were the big sellers,
weren't they? I would guess that the VAX 3100's and 4000's would be called
workstations even though they were more powerful that their predacessors.
It's the Unix boxen that confuse me the most, I supported the 3B2 line
of AT&T computers and they had the 3B1 (desktop/workstation/micro computer)
the 3B2 (micro/mini's), the 3B5/3B15 (mini), 3B20 Simplex/Duplex (main
frame?), and the 3b2/4000 (main frame? [4 3B2/1000's in parallel]).

Now to even throw a smaller wrench into the works, I worked with OS9 and
a Gimix Ghost. It had 2 meg of RAM, an 80 M MFM drive, 12 serial ports,
2 printer ports and a video interface (which we didn't use). This box
used a 6809 as it core processor, although every 4 serial ports had
a 6809 to handle buffering and skid (flow) control. I loved that box
and wish I had it now.
