The DECmate II, DEC Professional and the DEC Rainbow all used the
same style case. The DECmate III, and III+ use the same style as the
VAXstation 2000, and some external RZ5* SCSI drives, and the external
TK50 drives.

But when you're like me and have 3 different sets of RT-11 doc's, 1
1/2 sets of RSX-11M doc's, an Ultrix-11 set, a RSTS/E doc set, as
well as a lot of hardware doc's, and a few VMS Doc sets... All this
takes the more space than a few racks!

Of course then there are my 3 racks, various chassis, and boxes of
spare boards.

I'm pretty much to the point I agree that Emulation is the best way
to go. It generates less heat and noise, and takes less electricity
and room. In the hobbyist arena, very few people need specialized
