<p>As good as I can get with the limited docs online</p> <p><b>New page</b></p><div>[[Image:PDP-1160FrontConsole.jpg|250px|right|thumb|KY11-P front panel]]<br /> <br /> The '''KY11-P Programmer's Console''' is the [[front panel]] for the [[KD11-K CPU]] used in the [[PDP-11/60]]. It allows a programmer to display and deposit data in [[main memory]], and start, [[halt]] and [[single-step]] the [[Central Processing Unit|CPU]]. If the CPU has the DCS (Diagnostic Control Store), it can be activated.<br /> <br /> It consists of a large sub-assembly containing two [[printed circuit board|PCBs]], 6 digits of 7-segment displays, and a keypad. It is connected to the CPU by a [[flat cable]] which plugs into a [[Berg connector|Berg header]] in the console, and in the CPU. The sub-assembly also includes a printed plastic inlay, and a metal bezel which holds the inlay in position<br /> <br /> ==Displays and controls==<br /> <br /> The display shows memory [[address]]es and data. The 'Run' light indicates that the CPU is [[execute|executing]] [[instruction]]s.<br /> <br /> The keypad is used to enter both addresses and data. The 'L(Adrs)' (Load Address), 'Exam' (Examine), 'Dep' (Deposit), 'Start' and 'Continue' keys perform the named function. If the CPU is running, depressing the 'Halt/SI' key stops it; if halted, pressing it performs a single instruction.<br /> <br /> ==Implementation==<br /> <br /> Most front panel operations are implemented by [[microcode]] in the CPU. Therefore, the CPU must be basically fully functional for the front panel to work.<br /> <br /> {{semi-stub}}<br /> <br /> ==Further reading==<br /> <br /> * ''KY11-P Console Illustrated Parts Breakdown'' (EK-KY11P-IP) - not online<br /> <br /> ==External links==<br /> <br /> * [http://www.bitsavers.org/pdf/dec/pdp11/1160/EK-11060-OP-003_PDP-1160_installation_and_operation_manual_Feb78.pdf PDP-11/60 installation and operation manual] (EK-11060-OP-003) - the KY11-P is covered in Sections 1.2.3 and 3.2 (pp. 13-14 and 72-209 of the PDF)<br /> * [http://www.bitsavers.org/pdf/dec/pdp11/1160/MP00409_1160cpu_KD11-K.pdf 11/60 Basic Field Maintenance Print Set] (MP00409) - the KY11-P is covered on pp. 105-118 of the PDF<br /> <br /> [[Category: UNIBUS PDP-11s]]</div>
