ULTRIX-11 System Disk Load Program

This program loads the ULTRIX-11 ROOT and USR file systems
from the distribution media to the system disk.

Enter your answer to each question in lowercase, then
press the key.

To correct typing mistakes press the key to erase
a single character or to erase the entire line.

You will be asked a series of questions. If you need help
with the answer to any question, type the word `help’ or
a `?’ then press the key.

ULTRIX-11 Initial Setup Program

The ULTRIX-11 system is now up and running in SINGLE-USER mode.
This program performs the following initialization steps:

o Determines the system disk and processor types.

o Selects one of the preconfigured ULTRIX-11 kernels.

o Installs alternate versions of several commands.

o Initializes the error log file.

o Creates the special files for the system disk.

o Removes all unnecessary files.

SIMH is a suite of emulators. Of the emulated systems, the most widely used are probably the Vax (3900 and 780), PDP-11, PDP-10.

While a number of operating systems past to contemporary can be installed on the Vax 3900 (KA655) emulator, including OpenVMS, NetBSD, OpenBSD, and 4.3BSD Quasijarus, not so much is available for the relatively new Vax 780 emulator. Of interest are early versions of VMS, 32V Unix, and 4.2BSD.

My personal interest in the PDP-11 emulator is limited to V7 Unix.

The PDP-10 emulator will run ITS, TOPS-10, and TOPS-20. Sadly, the latter doesn’t support the late-stage versions of TOPS-20 sporting TCP/IP - which means that for the time being, KLH10 is the only choice.

NetBSD 3.0 (Vax)

This image has an empty root password; the network is unconfigured. The unpacked !NetBSD 3.0 sources are on a disk image of their own; it can be mounted using “mount /dev/ra3a /usr/src”.

Ultrix 11 v2.16 (pdp11)

You can install Ultrix in a pdp11 emulator from simh. You can get the tape image from Bitsavers: BB-X302B-BC_ULTRIX-11_V2_16USR_BIN_1984.tap.gz.
This is the config file for simh:

SET CLK 50HZ
SET CPU 11/24
SET CPU 256K

SET CR DISABLED
SET DZ DISABLED
SET HK DISABLED
SET LPT DISABLED
SET PTP DISABLED
SET PTR DISABLED
SET RHA DISABLED
SET RK DISABLED
SET RP DISABLED
SET RQ DISABLED
SET RX DISABLED
SET TQ DISABLED
SET VH DISABLED
SET XQ DISABLED

SET RL ENABLED
SET RL0 RL02
ATT RL0 ULT20.RL2

SET RHB ENABLED
SET TU ENABLED
SET TU TM03
SET TU0 TU77
ATT TU0 BB-X302B-BC_ULTRIX-11_V2_16USR_BIN_1984.tap

and here install pdp11 ultrix you can get a detailed boot/configuration. Documents are located in Bitsavers too.

The purpose of this project is to provide an emulation of the onboard Apollo guidance computers, along with some ancillary items needed to make the emulation do something interesting.

KLH-10 is probably the most accurate PDP-10 emulator and supports TOPS-20 7.x, something that simh currently does not.

KLH-10 will run the usual PDP-10 mainframe operating systems like

* TOPS-10
* TOPS-20
* ITS
