'''UNIBUS Device Address''' table; ranges given are inclusive, i.e. a block listed as xxxx00-04 contains three words: 00, 02 and 04.

Generally, [[QBUS#Variable_address_size|Q18]] [[QBUS]] versions of devices (where they exist) use the same addresses as the [[UNIBUS]] version; [[QBUS#Variable_address_size|Q22]] versions use the [[address]] as given here, with a "17" prepended. A few QBUS [[device controller|devices]] do not exist in UNIBUS form, and are listed in their own right: such cases can be detected by the device name, which is of the form 'xxV11'.

All devices which use exactly the same block of [[address space]] as another device are listed on a single line, separated by " - ". Some blocks overlap, but are not congruent. These are indicated thusly: "*" (on each of the two); "**" indicates a double overlap, etc (but these are not entirely correct).

"Reserved" means the block is specifically called out that way in a [[Digital Equipment Corporation|DEC]] document (source indicated).

[[Central Processing Unit|CPU]] [[register]]s marked as "[[PDP-11/73|11/73]]" also appear in the [[PDP-11/83|11/83]] and [[PDP-11/84|11/84]]. CPU registers marked as "11/83" also appear in the 11/84.

CPU [[memory management]] registers marked with "%" do not exist in CPUs with the [[PDP-11 Memory Management#Simplified subset|'11/40' type memory management]] ([[PDP-11/23|11/23]], [[PDP-11/24|11/24]], [[PDP-11/34|11/34]], [[PDP-11/40|11/40]], [[PDP-11/60|11/60]]).

Notes:

#0 - Per the appendix in the '76 11/70 and, '79-'80 PDP-11 Proc H'bks, the UNIBUS map is in 770200-366, not 200-372, but the '76 11/70 Proc H'bks say in the text (pg. 6-21) that it's 200-372.
