Description of PDP-8 pape-tape loading video by Dave Gesswein, May 19th 2008. [Edits by Herb Johnson July 2008] This video shows a example session running the disk monitor system. First we start the editor and make a change to the program. We then we use the Fortran compiler to compile and execute the program. This program reads some data values from a paper tape and prints statistics. Lastly we assemble a program and punch a binary tape you can use to run the program. This program uses very little data: a real program would punch more tape since paper tape only stores 10 bytes per inch. [To load a paper-tape based operating system would require more steps than this example.] The first step in running a paper tape system is to load the "RIM" loader. You load those 16 instructions by using the front panel and execute it. The second step is to load the binary loader tape. After that you can load the program you desire to run, such as an editor. YOu would use an editor to enter your program then punch it to tape. If you wanted to assemble that file you edited, you would have to load a binary loader, then the assembler program, then the program to assemble. [The assembler] would punch a paper tape you could load to execute the program. The binary loader format uses less tape than RIM but is a much longer program so not desirable to manually enter. On a teletype the binary loader would take about 40 seconds to load, the editor 3 minutes and the assembler 5 minutes. The high speed paper tape reader is 30 times faster. The 11/20 has the controller card that would attach to a PC05 paper tape reader which is very similar to [my] PC04 used on my PDP-8.
