Processor-Controller ConsoleThe processor-controller (P-C) console (Figure 22)provides the means for manual control of the P-Cduring debugging or operating phases.The basic operating features and controls providethe facility to:1. Start or stop instruction execution.2. Address core storage.3. Set up and store data or instructions.4. Communicate with the program via sense orprogram select switches.5. Control the cycling rate in the run, single storagecycle, single instruction, or single stepmodes.6. Interrupt the program manually.7. Trace each instruction.8. Reset all control circuitry and storage.9. Turn power on and off.10. Indicate basic machine conditions and status.11. Display storage words and register data.12. Write or clear storage protect bits.13. Clear core storage.PUSHBUTTON SWITCHES AND LIGHTSThere are two rows of pushbutton switches andlights. One row is at the top of the console (Figure23); another is at the bottom (Figure 24). The followingparagraphs describe the functions of theseswitches and lights.Clear StorageThis switch (CLEAR STOR) has four functions, describedin Figure 25. As the figure indicates, thedesired function is selected by setting the modeswitch and the write storage protect bits (WSPB)switch to the appropriate positions. The functionthus selected can then be executed by holding downCLEAR STOR while pressing START.The P-C cycles completely through all corestorage addresses during the execution of each clearstorage function.Program LoadThe program load switch (PROG LOAD) is used toload the first 1442 card or 1054 tape record into corestorage. This first card or tape record must containinstructions that initiate the loading of the remainingcards or tape records. (The P-C must be inrun mode for program operation.) It should be notedthat a program load operation does not alter thestatus of the interrupt mask register.The first card or tape record is read into corestorage, beginning at the location specified by the I-register.. Normally, RESET is pressed beforepressing PROG LOAD. This resets the I-register to/0000. After RESET is pressed, the I-register maybe manually altered to some address other than/0000. This allows the first card or tape record tobe placed at any location in core storage.In any case, upon completion of the transfer ofthe first card or tape record to core storage, theP-C automatically branches to location /0000 tobegin instruction execution. Therefore, location/0000 should contain a valid instruction.Only one input device can be used for initialprogram load (IPL). The first 1442 on the system isused for IPL. The 1054 is used for IPL when thereis no 1442 on the system.When the 1442 is used for IPL, it operates inpacked mode. The first card is read into 40 ascendingcore storage addresses beginning with the addressspecified by the I-register. The binary datafrom two card columns is stored in each core storagelocation. For example, binary data from cardcolumn 1 (rows 12 through 5) is read into core storagelocation /0000 (bit positions 8 through 15), andbinary data from card column 2 (rows 12 through 5)is read into the same core storage location (bitpositions 0 through 7). Card rows 6 through 9are not read into core storage. The remainderof the first card is read in the same manner,entering all odd numbered card columns in bitpositions 8 through 15 of their respective corestorage locations, and even numbered card columnsin bit positions 0 through 7 or their respectivecore storage locations.80
