PiDP-8/I Software

Hacking on the PiDP-8/I Software
====

If you are going to make any changes to the PiDP-8/I software, here are
some rules and hints to keep in mind while you work.


<a id="gs-fossil"></a>
Getting Started with Fossil
----

The PiDP-8/I software project is hosted using the [Fossil][fossil]
[distributed version control system][dvcs].  Fossil provides most of the
features of GitHub without having to put up with all of the complexities
of Git. In a lot of ways, Fossil is even simpler to use than Subversion.
See [Fossil Versus Git][fvg] for a well-balanced comparison of the
user-facing differences.

This guide will introduce you to some of the basics, but you should also
at least read the [Fossil Quick Start Guide][fqsg]. For a more thorough
introduction, I recommend [the Schimpf book][fbook]. If you have
questions about Fossil, you can ask on [the Fossil forum][ffor], where
I, your humble project maintainer, am active.

If you started with one of our PiDP-8/I [binary OS images][bosi] made in
or after April 2017, Fossil is already installed.

If you're starting from some other OS, Fossil won’t be installed by
default, but if it’s Debian-based (e.g. Raspbian) you can easily install


Fossil with:


    $ sudo apt install fossil

That command assumes you’re running it on a derivative of Debian Buster,
released in June 2019, or newer. Older Debian-based OSes shipped Fossil
1.x, which is too old to work with our Fossil repository. (We need 2.1
or higher.) You could dig up an old version of this document to learn
our workaround for that problem, but it’s better to upgrade to an OS
that includes a compatible version of Fossil.

Fossil is also available for all common desktop platforms.  One of [the
official binaries][fbin] may work on your system.

While Fossil does allow offline operation and local independent clones,
its default mode of operation is to try and keep the clones in sync as
much as possible.  Git works the way it does because it was designed to
meet the needs of the Linux kernel development project, which is
inherently federated, so Git tries to operate in a federated model as
well.  Fossil is better for smaller, more coherent teams, where there is
a single, clear goal for the project and a single primary host for its
project repository.  Fossil helps remote developers cooperate, whereas Git
helps remote developers go off on their own tangents for extended
periods of time and optionally sync back up with each other
occasionally.

Fossil is a better match for the way the PiDP-8/I software project
works: we want you to cooperate closely with us, not go off on wild
tangents.

For more on this topic, see [Fossil Versus Git][fvg] in the Fossil
documentation.

*   We require several tools and libraries that aren't always installed:

    *   A working C compiler and other standard Linux build tools,
        such as `make(1)`.

    *   The Raspberry Pi development libraries

    *   Python's `pexpect` library

        $ sudo pip install pexpect

<a id="preparing"></a>
## Preparing Your Pi

If you have a working Raspberry Pi setup, you can probably just skip
ahead.

If you’ve just barely unpacked Raspbian onto an SD card and are now
trying to get the PiDP-8/I software distribution working on it, stop and
go through the [Rasbperry Pi documentation][rpd] first. At the absolute
minimum, run `raspi-config` and make sure the Localization settings are
correct. The defaults are for the United Kingdom, home of the Raspberry
Pi Foundation, so unless you live there, the defaults are probably not
correct out of the box.

[rpd]: https://www.raspberrypi.org/documentation/


<a id="unpacking"></a>
## Getting the Software onto Your Pi

If you're reading this file within an unpacked distribution of the
PiDP-8/I software, you may skip this section, because you have
already achieved its aim.

    above, so you can use Fossil to update your software to the current
    version at any time, as long as the Pi is connected to the Internet.


<a id="unpacking"></a>
### Unpacking the Software on Your Pi

Having transferred the distribution file onto your Pi, unpack it with a

command roughly like:


    $ tar xvf /path/to/pidp8i-VERSION.tar.gz

The final argument to that command will vary depending on what you
downloaded, [how you transferred it to the Pi](#transferring), and where

you put it. If you used the `wget` command above, the path is simply

`pidp8i.tar.gz`, for example. After unpacking the tarball, you will have
a new directory beginning with `pidp8i`.  `cd` into that directory, then
proceed with the [configuration](#configuring) steps below.


<a id="help"></a>
### If You Need More Help

If the above material is not sufficient to get you started, you might

This software distribution builds and installs in the same way as most
other Linux/Unix software these days.  The short-and-sweet is:

    $ ./configure && make && sudo make install

The `configure` step is generally needed only the first time you build
the software in a new directory.  You may want to add options, described
[below](#options).

Subsequent software updates and rebuilds should not require that you
re-run the `configure` step, even if you gave custom options. The build
system detects when the configuration is outdated and re-runs the
`configure` script with the same options. If for some reason that
automatic re-configuration fails, you can kick it off manually:

    $ make reconfig

The “`make`” step above will take quite a while to run, especially on
the slower Pi boards. The longest single step is building the OS/8 disk
packs from source media. Be patient; the build process almost certainly
isn’t frozen.

If you’re on a multi-core Pi, You can speed the build process up some by
running “`tools/mmake`” instead of directly calling “`make`”. It runs
Make in a mode that lets it do a lot of work in parallel, making better
use of your multiple CPU cores.  That OS/8 media rebuild step is choked
down to a single thread, though, so this won’t help with that.  (This is
a generic, portable script, so if you’re a software developer, feel free
to reuse `mmake` and `corecount` on your own systems.)

Only the `make install` step needs to be done via “`sudo`”.  For the
most part, we’ve tried very hard to minimize the places where you need
to use root privileges to get something done within the PiDP-8/I
software distribution.


<a id="using"></a>
## Using the Software

After running “`sudo make install`” the first time, you will have to log
out and back in to get the installation’s “bin” directory into your
`PATH`.

For the most part, this software distribution works like the [old stable
2015.12.15 distribution][osd]. Its [documentation][oprj] therefore
describes this software too, for the most part. Beyond that, you might
find our [Learning More](/#learning) links helpful.

The largest user-visible difference between the two software
distributions is that many of the shell commands are different:

1.  To start the simulator running in the background:

        $ pidp8i start

    This will happen automatically on reboot unless you disable the
    service, such as in order to run one of the various [forks of Deeper
    Thought][dt2].

2.  To attach the terminal you're working on to the simulator:

        $ pidp8i

    (Yes, it's the same base command as above.  The `pidp8i` script uses
    its first argument to determine what you want it to do.  Without
    arguments, this is what it does.)

3.  To detach from the simulator's terminal interface while leaving the
    PiDP-8/I simulator running, type <kbd>Ctrl-A d</kbd>.  You can
    re-attach to it later with a `pidp8i` command.

4.  To shut the simulator down while attached to its terminal interface,
    type <kbd>Ctrl-E</kbd> to pause the simulator, then at the `simh>`
    prompt type `quit`.  Type `help` at that prompt to get some idea of
    what else you can do with the simulator command language, or read
    the [SIMH Users' Guide][sdoc].

5.  To shut the simulator down from the Raspbian command line:

        $ pidp8i stop

There are [other significant differences][mdif] between the old stable
distribution and this one. You’ll want to be familiar with that
documentation’s content before reading Oscar Vermeulen’s documentation,
as it still refers to his last release in December 2015.


<a id="systemd" name="unit"></a>
## The systemd Unit File

Starting with release 2019.04.25, the PiDP-8/I software distribution is
based on [systemd][systemd], since Raspbian is now on its third
systemd-based release.

One of the features systemd gives us is the ability to set the unit to
run as user-level service rather than as a system-wide service, which
means you no longer need the `sudo` prefix on commands to start, stop,
restart, and query the service. The only time you now need root
privileges when working with the PiDP-8/I software is when installing
it. After that, the software runs under your normal user account, as do
all of the commands you use to manipulate the background simulator
service.

As a result of these changes, none of these commands work any longer:

    $ sudo /etc/init.d/pidp8i start
    $ sudo service pidp8i stop
    $ sudo systemctl restart pidp8i

The correct forms, respectively, are:

    $ systemctl --user start pidp8i
    $ systemctl --user stop pidp8i
    $ systemctl --user restart pidp8i

These commands are long, so we have extended the `pidp8i` command to
build and run `systemctl` commands for you when you pass it arguments:

    $ pidp8i start
    $ pidp8i stop
    $ pidp8i restart
    $ pidp8i status -l

If you run it without arguments, it attaches to the GNU screen(1)
session, just as it always has.

The last command above shows that *all* arguments are passed to
`systemctl`, not just the first, so you can pass any flags that
`systemctl` accepts.

Our systemd service starts at boot by default after you install the
software. To disable the service so you can run something else against
the PiDP-8/I front panel hardware instead, such as Deeper Thought 2:

    $ pidp8i stop
    $ pidp8i disable

If you install this release on a system that has the old SysV init
script on it, that service will be disabled and removed before we
install and enable the replacement systemd user service.

<a id="options"></a>
### Configure Script Options

You can change many things about the way the software is built and
installed by giving options to the `configure` script:

    right thing." The simulator is configured to send lowercase input to
    the PDP-8 software running on it. Where we have the skill, will,
    need, and time for it, we have [patched][tty] some of the software
    we distribute that otherwise would not do the right thing with
    lowercase input to make it do so.

    This is *not* the option you want if you are a purist.

*   **pass** — This passes keyboard input through to the simulator
    unchanged, and no patches are applied to the PDP-8 software we
    distribute.

    This is the option for historical purists. If you run into trouble
    getting the software to work as you expect when built in this mode,
    try enabling CAPS LOCK.

*   **upper** — This option tells the PDP-8 simulator to turn lowercase
    input into upper case. This is the behavior we used for all versions
    of the PiDP-8/I software up through v2017.04.04.  Essentially, it
    tells the software that you want it to behave as through you've got
    it connected to an uppercase-only terminal like the Teletype Model 33 ASR.

    The advantage of this mode is that you will have no problems running
    PDP-8 software that does not understand lowercase ASCII text.

    The disadvantage is obvious: you won't be able to input lowercase
    ASCII text.

    The SIMH option we enable in this mode is bidirectional, so that if
    you run a program that does emit lowercase ASCII text — such as Rick
    Murphy's version of Adventure — it will be uppercased, just like an
    ASR-33 would do.

    Another trap here is that the C programming language requires
    lowercase text, so you will get a warning if you leave the default
    option **--enable-os8-cc8** set. Pass **--disable-os8-cc8** when
    enabling **upper** mode.

<a id="nls"></a>
#### --no-lamp-simulator

    That having been said, people don't go to a ren fair and expect to
    experience the historical ubiquity of typhoid fever, so do not feel
    guilty if you choose to try this option.

[uvte]: https://tangentsoft.com/pidp8i/wiki?name=Using+VTEDIT

*   **--enable-os8-focal69** — Because the default installation includes
    U/W FOCAL, we have chosen to leave [FOCAL,1969][f69] out by default
    to save space on the O/S 8 system disk. You can give this option to
    install this implementation alongside U/W FOCAL, or you can couple
    this option with `--disable-os8-uwfocal` to reverse our choice of
    which FOCAL implementation to install by default.

    You should know that the reason we made this choice is that the
    version of FOCAL,1969 we are currently shipping is fairly minimal: we
    believe we are shipping the original DEC version of FOCAL,1969 plus a
    few carefully-selected overlays. There are many more overlays and
    patches available on the Internet for FOCAL,1969, but we have not had
    time to sort through these and make choices of which ones to ship or
    how to manage which ones get installed. Thus our choice: we want to
    provide the most functional version of FOCAL by default, and within
    the limitations of the time we have chosen to spend on this, that is
    U/W FOCAL today.

    (See our [U/W FOCAL manual supplement][suppd] for a list of
    differences between these versions of FOCAL, which implicitly
    explains why we chose it.)

    It is possible that we will eventually add enough patches and
    overlays to FOCAL,1969 that it will become more powerful than U/W
    FOCAL, so we might then choose to switch the defaults, but that is
    just speculation at the time of this writing.

[suppd]: https://tangentsoft.com/pidp8i/doc/trunk/doc/uwfocal-manual-supp.md#diffs


#### --os8-minimal

If you set this flag, it sets all `--enable-os8-*` flags to false and
all `--disable-os8-*` flags to true.  If you give this along with any

switches on the front panel.  After you are done testing, you can start
the PiDP-8/I simulator back up with:

    $ pidp8i start

See [its documentation][test] for more details.

## Enabling the SSH Server on the Binary OS Images

The OpenSSH server is enabled and running by default on the PiDP-8/I
binary OS images, but for security reasons, the build process we use
to create these OS images wipes out the SSH host keys generated here

You may be wondering why we don’t do this automatically, somehow. It’s
because, over time, we’ve removed all dependence on root access in our
software in the name of security, so that we no longer have permission
to make system-wide changes like this in our startup scripts.  We now
rely on you, the system’s administrator, to do it interactively with
`sudo` permissions.
