README
Compile and run Joseph Weizenbaum's original 1965 code for
[ELIZA](https://sites.google.com/view/elizaarchaeology/home) on
[CTSS](https://en.wikipedia.org/wiki/Compatible_Time-Sharing_System),
using the s709 IBM 7094 emulator.
* [elizagen.org blog
post](https://sites.google.com/view/elizagen-org/blog/eliza-reanimated)
* [Video demo](https://youtu.be/j5Tw-XVcsRE)
## Prerequisites
You will need a Unix like environment that can compile C code and run
Python and shell scripts. This has been tested on
* Arch Linux
* Debian
* MacOS
but may work on other Unix/Linux flavours.
You will also need the `telnet` command line program or a GUI telnet
client. The command line program can be installed by `sudo apt install
telnet` on Debian/Ubuntu or `brew install telnet` on MacOS.
## Quickstart
If you just want to try ELIZA, follow the below steps to bring up CTSS
and get ELIZA compiled and running. If you'd like to find out more
about each step, see [`HACKING.md`](HACKING.md).
1. Fetch this repo and set up the environment.
```
$ git clone https://github.com/rupertl/eliza-ctss.git
$ cd eliza-ctss
$ source env.sh
$ make-binaries
$ make-disks
```
2. The next two commands will prompt you to press Enter a number of
times and then `q` to quit.
```
$ format-disks
$ install-disk-loader
```
3. Continue installing CTSS and the ELIZA source.
```
$ installctss
$ add-eliza-users
$ upload-all
```
4. Start CTSS by typing `runctss`
5. Start your telnet client and connect to localhost port 7094. For
the command line client you can type `telnet 0 7094`.
6. In the telnet session, type `login slip` and give the password `slip`
7. The screen should now look something like
```
$ telnet 0 7094
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.

```
8. Type `runcom make`
9. A long series of compile messages should follow, ending with
itprinting `MAKE HAS BEEN RUN `
10. Type `login eliza` and give the password `eliza`
11. Type `runcom make` again and wait for the `MAKE HAS BEEN RUN`
message.
12. Type `r eliza`
13. Give the answer `200` to the prompt of which script to use
14. ELIZA will print a greeting and you can now interact with her.
Keep your responses below 72 characters and press Enter twice to
submit. This is how your screen could look after a first response.
```
r eliza
W 1331.5
EXECUTION.
WHICH SCRIPT DO YOU WISH TO PLAY

HOW DO YOU DO . PLEASE TELL ME YOUR PROBLEM

INPUT
```
15. When you are finished, press `Control-\ ` (backslash) to interrupt and then
type `logout`.
16. Shut down CTSS cleanly. You will need to switch back to the
*main emulator window* you started earlier - this cannot be done
from the telnet session.
Execute the following, pressing Enter after each non Control-C line.
* Press Control-C
* Type `ek 40017`
* Type `st`
* Press Control-C
* Type `ek 0`
* Type `st`
* Press Control-C
* Type `ek 40032`
* Type `st`
* Type `q` and Enter to exit.
17. If you want to run ELIZA again, do `runctss` and then telnet in as
user `eliza` and `r eliza` like before. (You do not need to recompile it).
For more details on any of these steps, and to find out how to make
changes to the source code, see [`HACKING.md`](HACKING.md).
## The reconstruction process
[`RECONSTRUCTION-CARD.md`](RECONSTRUCTION-CARD.md) contains details on
how we got ELIZA into a running state.
## Known bugs and issues
The goal of this repository is to get ELIZA running in its original
form with as few modifications as possible. There are missing features
and bugs from the original code: see
[`KNOWN-ISSUES.md`](KNOWN-ISSUES.md) for details.
## Sources and licences
The ELIZA and SLIP library code under `eliza/` is from the source code
[printout](https://sites.google.com/view/elizagen-org/original-eliza)
which was found among Weizenbaum's papers at MIT by Jeff Shrager and
the MIT archivists, and
[transcribed](https://github.com/jeffshrager/elizagen.org/tree/master/1965_Weizenbaum_MAD-SLIP)
by Anthony Hay and Arthur Schwarz respectively. Weizenbaum's estate
has kindly agreed for this to be open sourced under a [Creative
Commons CC0 public domain
license](https://creativecommons.org/publicdomain/zero/1.0/). About 4%
of the SLIP library were missing in the original printout; these were
re-implemented by Anthony, Arthur and Rupert Lane and are found in
`eliza/src/SLIP/SLIP-reconstructed` with tests in `SLIP-tests`. This
newer work is also licenses as CC0.
The s709 emulator, ctss-kit and utilities under `ctss/` are from Dave
Pitts' [IBM 7090/7094 page](https://cozx.com/dpitts/ibm7090.html),
based on previous work on s709 by Paul Pierce, with minor
modifications by Rupert. This uses the MIT license, see
[LICENSE.txt](ctss/LICENSE.txt).
CTSS environment set up, upload and runcom scripts are by Rupert,
licensed as CC0.
The ELIZA script
[`eliza/src/ELIZA/tape.200`](eliza/src/ELIZA/tape.200) is adapted from
Weizenbaum's article for the _Communications of the ACM_ in 1966.
