1 | How to build the mandelbrot-demo program |
2 | |
3 | 1. Needed |
4 | |
5 | - source files (found in mandelbrot-demo.tar.gz): |
6 | apfel.f |
7 | pchar.asm |
8 | |
9 | - compiler, assembler, loader, punch program (found in tape-images.new.tar.gz): |
10 | SLST-FRTN.img |
11 | SLST-LDR-APM.img |
12 | OBJECT-PAL-AP.img |
13 | SLST-DAP-16.img |
14 | |
15 | - fortran library, 3 files (found in tape-images.new.tar.gz): |
16 | LIBRARY-FORT_LIB_1.img |
17 | LIBRARY-FOR_LIB_2S.img |
18 | LIBRARY-FORT_LIB_3.img |
19 | |
20 | |
21 | 1. Prepare source files. |
22 | - You have to change the source files to <CR><LF> line termination (MS-DOS style) |
23 | - Then you have to set the 8th bit on all data - yes, you can't it read anymore... |
24 | There are also some tricks with an & in the emulator... |
25 | |
26 | - Remove my header from the SLST files. In library files no problem. |
27 | |
28 | - If you use the Emulator: go to step 2. |
29 | - If you use the original machine: punch out the source tapes :-) |
30 | |
31 | 2. Build pchar routine |
32 | PCHAR is a little assembler routine allowing simplest unformatted io. |
33 | |
34 | - Boot SLST-DAP-16.img |
35 | - MSTCLR |
36 | - A reg: Set bits: |
37 | -1 Two-pass assembly |
38 | -3 Input from high-speed paper tape |
39 | -11 NO object output |
40 | -12 Listing on teletype |
41 | - P reg: '1000 |
42 | |
43 | |
44 | Real machine: |
45 | |
46 | - Mount the source tape into the high speed reader, turn on ASR |
47 | - press START and wait..... |
48 | - Assembly should stop at the end of text on the tape. Tape should not |
49 | run out. |
50 | - Reposition tape to the beginning. |
51 | - Press start again. |
52 | - After completion the assembler says "AC". With or without errors!! |
53 | |
54 | Now you have a listing. Let's build the object file: |
55 | |
56 | - Mount the source tape into the high speed reader, turn on ASR punch |
57 | - A-reg bits 1-3-7-16 (no listing, object to asr, no listing) |
58 | - P-REG 1000 |
59 | - Reposition tape to the beginning. |
60 | - Press start again. |
61 | - After completion the assembler says "AC". With or without errors!! |
62 | |
63 | Now you have the pchar object. Need it later. |
64 | |
65 | Emulator: |
66 | - Same register settings as on real machine. |
67 | - Press START, emulator will ask for "ptr" file. |
68 | - enter "pchar.par" or whatever you have chosen for the converted file. |
69 | - The assembler will stop. |
70 | - Press START again. |
71 | - Will say EOF and ask for more paper. give source file again. |
72 | - Should print listing and say "AC" |
73 | |
74 | Make the object: |
75 | - A-reg 1-3-8-16, P-reg '1000 |
76 | - Same procedure but answer the questions "ptp" with your new |
77 | object's filename, "pchar.obj" for example. |
78 | - Notice: look closely if you're asked for PTP or PTR. If you enter your |
79 | source file name at PTP it will be erased instantly!! |
80 | - Leave emulator program. Important to really close. |
81 | |
82 | Now you have the pchar object. Need it later. |
83 | |
84 | NOTICE: Sometimes the emulator asks for a file |
85 | and does not echo your keystrokes. |
86 | BUT IT WORKS!!!! |
87 | |
88 | |
89 | 3. Build mail object file |
90 | - That's easier than using the two-pass assembler....! |
91 | - Boot SLST-FRTN.img |
92 | - MSTRCLR |
93 | - A-reg settings: |
94 | -'000310: Listing on ASR, suppress verbosity by setting sense switch 2 |
95 | -'000302: Object output to ASR |
96 | - Operation: |
97 | -Start at '1000 like with the assembler. But only one pass. |
98 | -Will type "end of job".... |
99 | - Now you should have two different object tapes or files. |
100 | - Leave emulator!!!! |
101 | |
102 | 4. Putting all together |
103 | - Boot SLST-LDR-APM.img |
104 | - MSTRCLR |
105 | - Change contents of memory address '15000 to '17777 or '37777 |
106 | - MSTRCLR |
107 | - A-reg '17000, P-reg '16000 |
108 | - OBJECT-PAL-AP.img needed. Mount tape now if using real hardware |
109 | - Press START TWICE |
110 | - if using emulator, enter "OBJECT-PAL-AP.img" at the PTR prompt |
111 | - LDR-APM now loads PAL-AP. Should say LC when ready. If it says CK you |
112 | have a checksum error on the tape. If tape runs out you have a problem |
113 | |
114 | Now load apfel.obj: |
115 | - MSTRCLR |
116 | - P-reg '16000 A-reg '1000 |
117 | - now the usual sequence "tape and start" for real machine, and "start and tape" |
118 | for emulator. using apfel.obj |
119 | - Will say MR. Means that you have unresolved symbols. |
120 | - If you like to you can set P-reg to '16002' and start. You'll get a memory map. |
121 | |
122 | - Go on loading with pchar.obj. Loading continues if START is pressed |
123 | - Now process the library files the same way. The order is important. 1,2,3 |
124 | - If you have managed this you will get LC (loading complete). |
125 | |
126 | Now the application is ready to run. But wait! Don't you want to generate a |
127 | self loading system tape (SLST) with PAL-AP? Sure! So you can always restore the |
128 | actual state without doing all the patching stuff. |
129 | |
130 | - Punch on ASR on. |
131 | - P-reg '17000', A-reg set only bit 1. |
132 | - Press START. Computer will halt. |
133 | - Enter '100 to A-reg and press START. Will halt again. |
134 | - Enter '6700 to A-reg and press START. Will begin to punch |
135 | self loading tape. (or ask for file etc... ASRPTP) |
136 | |
137 | Now you have the SLST and can easily load the program by booting the tape. |
138 | |
139 | 5. Start the program |
140 | - When the program is loaded start the computer at '1000. That's all. |
141 | - When program is ready PA will be printed and CP halts. If you press START |
142 | it will start a new run. |
143 | |
144 | 6. Good luck. I hope I have described enough... |
