<p>Notnmuch to say</p> <p><b>New page</b></p><div>The '''KC11 CPU''' was the [[Central Processing Unit|CPU]] of the [[PDP-11/15]], the [[Original Equipment Manufacturer|OEM]] version of the [[PDP-11/20]]. It was essentially the [[KA11 CPU]] of the PDP-11/20, with several minor emendations to justify a lower price:<br /> <br /> * Only one [[interrupt]] priority level on the [[UNIBUS]]<br /> * No power fail/restart support<br /> <br /> Both the 4-level priority support and power fail/restart were available as options: the '''KF11-A''' ('''M7218''') and '''KP11-A''' ('''M7217''').<br /> <br /> The 'basic' [[front panel]] of the PDP-11/15 was the KY11-B; it had only 'power' and 'run' lights, and 'start', 'halt' and 'continue' switches. It could be upgraded to the KY11-C, which was basically identical to the [[KY11-A Programmer's Console]] of the KA11, except that it had only 16 [[address]] switches, instead of 18.<br /> <br /> {{semi-stub}}<br /> <br /> ==External links==<br /> <br /> * [http://www.bitsavers.org/pdf/dec/pdp11/1120/PDP11_15_KC11_Block_Diagram.pdf KC11 Block Diagram]<br /> * [http://www.bitsavers.org/pdf/dec/pdp11/1120/PDP-11_15FP_KY11-C.pdf KY11-C programmer's console engineering drawings] (DEC-11-HYCA-D)<br /> * [http://www.bitsavers.org/pdf/dec/pdp11/1120/M7218_PDP11_15_Bus_Requests.pdf M7218 Bus Requests]<br /> * [http://www.bitsavers.org/pdf/dec/pdp11/1120/M7217_PDP11_15_PWRFAIL_RESTART.pdf M7217 Power Fail &amp; Restart]<br /> <br /> [[Category: PDP-11 UNIBUS Processors]]</div>
