  Well no, while you can have a complete system in one rack, most 11/70 systems
are several racks. I was pointing out that the processor *alone* is half a
rack.

  Both the pdp11 and vax families have very large and very small members. A
MicroVAX 2000, for example, is about the size of a lunchbox. Look for a BA23
or BA123 chassis...they're small deskside (though the BA23 can be tabletop or
rack-mounted easily) cabinets that can hold either a qbus pdp11 or a qbus
MicroVAX/VAXstation. pdp11 systems to look for would be pdp11/23, /53, /73,
or /83, while the VAXstation systems in those chassis could be anything from a
MicroVAX-II to a VAX4000/200.

  If you need more specific info, mail the list or me personally...we can help
you out. Most of us here are running systems like those nowadays, I'd guess.
