DEC PDP-11 Tape Images
----------------------
We have archived the following DEC PDP-11 Tapes:
To load any of the DEC PDP-11 tapes listed below, you will need to use a [PDPjs Machine](/devices/pdp11/machine/)
with a [PC11 High-Speed Paper Tape Reader/Punch](/devices/pdp11/pc11/), such as this
[PDP-11/20](/devices/pdp11/machine/1120/basic/debugger), and then follow this three-step process:
- [Absolute Loader](absloader/)
- [BASIC (Single User)](basic/)
- Load the [DEC PDP-11 Bootstrap Loader](/apps/pdp11/boot/bootstrap/)
- Attach the [Absolute Loader](absloader/) tape image, and load it with the Bootstrap Loader
- Attach one of the "Absolute Format" tape images below, and load it with the Absolute Loader
along with a copy of the [DEC PDP-11 Bootstrap Loader](/apps/pdp11/boot/bootstrap/), which is required if you actually want
to load any of the above tapes into memory using the [PC11 High-Speed Paper Tape Reader/Punch](/devices/pdp11/pc11/).
This was the real-world process. Fortunately, PDPjs machines include features that simplify the process.
For the most part, the tapes we have archived are in the DEC "Absolute Format". More information about that format
is on the [Absolute Loader](absloader/) page.
For starters, any "Absolute Format" tape (which should include all the tapes listed below) can be loaded directly
into RAM using the machine's "Load" button instead of "Attach". In most cases, this eliminates the first two steps.

As documented in the [PDP-11/20 Handbook (1971)](http://archive.pcjs.org/pubs/dec/pdp11/1120/PDP1120_Handbook_1971.pdf),
p. 155, "PAPER TAPE SOFTWARE", the following software was available on paper tape:
- PAL-11A ASSEMBLER
- [PAL-11A ASSEMBLER](pal11a/)
- PAL-11S ASSEMBLER (Program Assembly Language for the PDP-11, Relocatable Version)
- ED-11 (Text Editor program)
- DUMPTT (Dump Octal)
- DUMPAB (Dump Absolute Binary Code)
- FPP-11 (Floating-Point and Math Package for the PDP-11)
- ODT-11 (On-line Debugging Technique for the PDP-11)
- IOX (PDP-11 Input/Output eXecutive)
- PDP-11 BASIC (Beginners All-purpose Symbolic Instruction Code)
- [ED-11](ed11/) (Text Editor program)
- [DUMPTT](dumptt/) (Dump Octal)
- [DUMPAB](dumpab/) (Dump Absolute Binary Code)

There was a separate DEC publication, [PDP-11 Paper Tape Software Handbook](http://archive.pcjs.org/pubs/dec/pdp11/other/DEC-11-XPTSA-B-D_PDP-11_Paper_Tape_Software_Handbook.pdf),
that described all of the above software in greater detail, and it included some programs that the 1971 Handbook listed under
