: : IDEWTIFICATIOK PRODUCT CODE: DEC-14-MWZB -D PRODUCT NAME: run-14 DATE CREATED: JUNE 18, 1970 MAINTAINED DIAGNOSTIC GROUP AUTHOR EDUARD P. STEINBERGER 1 1 . ABSTRACT RUN-14 is a program, written in PDP-8 language, which allows a PDP-8-type computer connected to a POP- 14 to act as the memory of the PDP-14 and allow the PDP-14 to execute the PDP-14 program contained in the PDP-8 memory. 2. LOADING PROCEDURE RUN- 14 is loaded into PDP-8 memory using the "standard" binary loader technique. 3. USING THE PROGRAM 3.1 Load RUN-14 into 8 memory using the Binary Loader program (Note: Load into memory bank 1 if a 4K PDP-14 program is to be run, otherwise, load into memory bank 0). 3.2 Load LOAD- 14 into 8 memory using the Binary Loader program (See Note in 3.1) 3.3 Use LOAD- 14 to read into 8 memory the binary image(s) of the PDP-14 program to be run, into memory bank 0. 3.4 Power down the PDP-8 l/L, connect the PDP-14 to the PD P —8 l/L using the appropriate cables and revision of the M745 interface module. Install INPUT and OUTPUT Register modules (M746's). Power up the PDP-8 l/L. (Ignore this paragraph is PDP-14 is already connected to the 8 and the modules plugged in). 3.5 Power up the PDP-14 computer while depressing PDP-14 "STOP" 3.6.1 If a 4K PDP-14 program is to be executed, set IF switches to 1, DF switches to 0, Switch Register (SR) to 6000, depress "LOAD ADDRESS". 3.6.2 PDP-14 program is to be executed, set IF switches to 0, DF switches to 0, SR to 6001, depress "LOAD If a IK ADDRESS". 3.7 Set SR to starting address (4K)of PDP-14 program (usually 0000), depress PDP-8 l/L "START". 3.8 Depress PDP-14 "START", . 2 3.9 PDP-14 program will be executed by the PDP-14 using PDP-8 l/L memory for instructions and memory source data. 3.10 If the PDP-14 loaded its OUTPUT Register because of an instruction in the PDP-14 program, the number in the OUTPUT Register will be typed out on the teleprinter in the form: OUTPUT =XXXX 3.11 If the PDP-14 stops, RUN-14 will type out a message in the form: PDP-14 STOPPED AT XXXX RUN-14 will then wait for the operator to depress PDP-14 "CONTINUE". 3.14 if for some unknown reason the PDP-14 hangs (does not complete an instruction), RUN- 14 will type out: PDP-14 HUNG 4. DETAILS OF OPERATION 4.1 Upon starting, the program decides whether a IK or 4K program to be executed and sets up an address mask accordingly (The decision is made by the address at which the program is is started) 4.2 The program then obtains the starting address of the PDP-14 program from the SR and saves it. 4.3 Upon de-cection of the PDP-14 running, the 14 is interrupted and placed in the external mode. PCI is then loaded uaiiig a 6164 lOT to load and execute a PDP-14 JliP iJIJIM Instruction. 4.4. The PDP-14 is checked to see if it is still running. contents of PCI is If so, the read into the 8 AC to determine the location of the next instruction to be executed by the 14. If the 14 not running, RUN-14 waits for 14 "CONTINUE" to be depressed, and "PDP-14 STOPPED AT c(PCl)" is displayed. is 4.5 The next 14 instruction is then obtained from memory and sent to the 14 for execution. 4.6 The instruction obtained by 4.5 (above) is checked to see if it is a 2-word instruction. If it is, the program goes to 4.7. If it is not, the program goes to 4.8. 4.7 The second word of the 2-word instruction is obtained from 8 memory and sent to the 14. 3 4.8 If the OUTPUT Register flag is set, the contents of the OUTPUT Register is typed out on the teleprinter. then goes back to 4.4. In any case, the program PAL10 / Vl81 18-JUN-70 21108 PACE 1 1 2 3 /BUN 14 4 / 5 6 /COPYRIGHT 1970, DIGITAL E8UIPMENT COHP, MAYNAPD, MASS, 7 / 8 /PROGRAM TO execute A PROGRAM |N ThE MEMORY OF A PDP-B /ON A PDP"14, THE P0P"l4 IS RUN IN EXTERNAL MODE, /the pdp-14 pci register is accessed after each /INSTRUCTION TRANSFER OF THE PDP-8 TO SEE FROM /where the NEXT MEMORY REFERENCE SHOUI.D BE OBTAINED /THE PDP-14 PROGRAM OCCUPIES PDPi.8 MEMORY FROM LOCATION 00000 /THIS PROGRAM SHOULD BE LOADED INTO MEMORY BANK 1 IF /A 4K POP-14 PROGRAM HAS BEEN LOADED INTO MEMORY BANK 0 /START RUN14 AT LOCATION 6000 IF A 4K POP-14 /program is being RUN /START RUN14 AT 6001 IF A IK POP-14 PROGRAM /starting address of PPp-14 program is In SWITCH REGISTER /IF the pop-14 STOPS, This program will loop at location "loop" /UNTIL PdP»14 "CONTINUE" IS OEPRESSEOi /IF A load output register instruction is GIVENi the /PROGRAM WILL TYPE OUT THE /contents of the output register / on The pop-8 teletype and continue the program / 9 10 11 12 li 14 15 14 17 1§ 19 20 21 22 23 24 25 26 27 28 29 30 3i 32 33 34 35 36 37 38 3« 40 4i 42 43 44 45 46 47 48 49 50 51 52 53 5^ 55 ' 6000 6001 6002 6003 6004 6005 6006 6007 6010 6011 6012 6013 6014 6015 6016 6017 6020 6021 6022 6023 6024 6025 6026 6027 6030 6031 6032 6000 • 6000 1315 1313 3316 7604 3307 6175 5205 RUN14, 1^2 4777' 1307 4776' 6175 5213 7200 1310 6165 4221 0000 6175 5317 6161 7410 5232 2221 5222 4327 6171 LOOP, tad K6000 TAD K1777 OCA MASK LAS OCA PCI SCRF JMP ,-l TAD K0600 jMs inter TAD PCI JMS SETPCl SCRF JMP ,-1 CLA TAD K0246 ILEX JMS ,*1 0 /set up pci mask for IK or 4K /set pci to starting address /wait for some one to depress pdp-14 start /interrupt pdp-14 to execute an EEM /SET PCI to starting ADDRESS OF POP-14 PROCRAM, /IS the pdp-14 still running /NO /YES /interrupt POP-14 /TO EXECUTE /TRR PI, OT SCRF JMP NORUN sidf SKP JMP ,*4 IS2 ,-6 JMP ,-6 JMS TYMOUT SOTF /OUTPUT flag set? / 56 57 58 59 60 61 62 63 6A 65 66 67 68 65 70 7i 72 73 7A 75 76 PAL10 VIA! 6033 6034 6035 6036 6037 6040 6041 6042 6043 6044 6045 6046 6047 6050 6051 6052 6053 6054 6055 6056 6057 7402 6176 0316 3307 1707 6164 4242 0000 6175 5317 6161 7410 5253 2242 5243 4327 0260 1314 7640 5275 2307 21108 18"JUN»70 HWT ROTR ANO mask DCA PCI TAD I PCI LOCK JHS i*i PACE a=<i /NO /YCSi READ BACK NEW PCI /GET NEXT INSTRUCTION /EXECUTE IT 0 SCRP JMP NORUN SIOF SKP JMP ,*4 IS2 JMP JMS AND TAO sza JMP ,"6 ,^6 TYMOUT K7000 K<4000 cua /two WORDT PROCED /NO ISZ PCI /YESiBUMP PCI PAtl0 t 77 78 7V 88 8i 88 8A 88 86 87 88 8» 9i 9i 92 93 94 95 96 97 98 99 180 101 10Z 103 104 105 106 107 108 109 118 111 IIZ ii3 ii! 115 116 117 iiS ll9 120 i2i 122 123 124 6060 6061 6062 6063 6064 6065 6066 6067 6070 6071 6072 6073 6074 6075 6076 6077 6100 6101 6102 6103 6104 6105 6106 6107 6110 61ll 6112 6113 6114 6115 6116 6117 6120 6121 6122 6123 6124 6125 6126 6127 6130 6131 6132 6133 6134 6135 6136 Vl41 18"JUN^>70 7000 1707 6164 4264 0000 6175 5317 6161 7410 5275 2264 5265 4327 6171 5213 7280 A775' 17741 4773' 6176 4772' 4775' 5213 0000 0246 0264 0600 1777 4800 6000 0000 7200 4775' 1771' 4773' 1307 4772' 4775' 5213 0000 7208 4775' 17701 4773' 47751 7402 5727 K7000I 21188 NOP TAO 1 PCI ldex JMS ,*1 page 2 /GET SECOND WORD /TRANSFER IT TO POP’l^ 0 SCRF JMP NORUN SIDF SKP jMP ,*4 ISZ PROCEO , PCI, K0246I K8264i K0600, K1777» K4000I K6000, mask, NQRUNt TVMOUT • ,"6 JMP ,=>6 JMS TVMOUT SOTF JMP LOOP cla JMS CRLF TAO OUTPUT JMS MESAG ROTR JMS PRINT JMS CRLF JMP LOOP 0 246 264 600 1777 4808 6808 0 CLA JMS TAO JMS TAO JMS JMS JMP CRLF PNORUN MESAG pci PRINT CRLF LOOP 8 CLA JMS TAD JRS JMS HLT JMP CRLF PHUNG MESAG CRLF I TTMOUT /OUTPUT register LOADED? /NO /READ OUTPUT REGISTER PAI.10 129 126 12? 128 12? 138 131 132 133 134 139 136 137 13B 13» 140 141 142 143 144 149 14i 147 146 14V 150 isi 152 153 194 155 156 157 156 155 160 6170 6l7i 6172 6173 6174 6175 6176 6177 V141 l|»JUN-'70 6336 6312 6254 6353 6301 6242 6221 6015 6200 •6200 PARE 3 / /check PDP«14 running / 6200 6201 6202 6203 6204 6209 6206 6207 6210 6211 6212 6213 6214 0000 4202 0000 6175 5777* 6161 7410 5213 2202 5203 4776* 7200 5600 HAITI 0 JNS i6l 0 SCflF JNP NORUN SIOF SKP JMP ,*4 192 ,«6 JMP ,"6 JMS TTMoUT CUA JMP I HAIT / /INTERRUPT THE P0P"14 / 6219 6216 6217 6220 0000 6165 4200 5615 inter* 0 ILEX JMS HAIT JMP I INTER / /SET PCI TO NNNN USIN / 7-61 162 163 164 169 166 167 166 165 170 17i 172 173 174 175 376 177 178 SyOB 6221 6222 6223 6224 6225 6226 6227 6230 6231 6232 6233 0000 3232 1233 6164 4200 1232 6164 4200 5621 0000 4224 SETPCl. 0 OCA SETTEM TAO K4224 loex JMS HAIT TAO SETTEM UOEX JMS WAIT JMP I SETPCl SETTEM, 0 4224 K4224r / / /type subroutine 6234 6235 0000 6046 TYPE, 0 tls /SAyE NNNNi /EXECUTE POP-AA JHPi /WAIT FOR DONE FUACi /SET PCI TO NNNN, /WAIT FOR done FUAO, /EXIT. /CODE FOR PSP-aiA JMP INST.
