 The '''PDP-11/15''' is the [[Original Equipment Manufacturer|OEM]] version of the [[PDP-11/20]]. Its [[hardware]] is not completely identical to the -11/20, though; its [[KC11 CPU]] is slightly different from the [[KA11 CPU]] of the -11/20 (although the KC11 contains mostly the same boards as the KA11).
 The KC11 only supports a single [[interrupt]] priority level (and thus has only a single interrupt [[bus grant line]] on its [[UNIBUS]]). It could be upgraded to the 4-level of the KA11 by the optional [[KF11-A]]. The KC11 also does not have [[power fail/restart]]; this could be added with the [[KP11-A]].
-The [[Central Processing Unit|CPU]] manual ("pdp11/20-15-r20 processor handbook") claims (pg. 137) that the KC11's [[KY11-A Programmer's Console]] has only 16 address lights and switches, unlike the 18 of the KA11, but images of PDP-11/15 [[front panel]]s show 18 locations for address lights (although it is possible that there are no actual lights behind the two left-most locations).
