# Installation of the SimH pdp11 simulator
The w11 project uses the pdp11 simulator from the
[SimH](https://en.wikipedia.org/wiki/SIMH) project. The project was started
by Bob Supnik under [simh.trailing-edge.com](http://simh.trailing-edge.com).
This site contains the "classic" version of SimH, the 3.X stream, with v3.11-1
as the last release. Since about 2014 the project is continued by a team led by
Mark Pizzolato as GitHub project [simh/simh](https://github.com/simh/simh).
The new, functionally much enhanced, version is called V4.*. However, the
team decided not to provide releases anymore, just a stream of commits,
more than 4200 as of April 2022.
Debian and Ubuntu offer `simh` packages, but with the obsolete version V3.8.1,
released in February 2009. The main obstacle to the inclusion of newer
versions is, according to the Debian maintainer, the unclear license situation.
The only practical way to obtain the pdp11 simulator is by installation from
sources. The GitHub repository contains also the classical versions, nicely
marked with tags.
The `scmd` scripts provided in the w11 project were originally developed for
SimH 3.8, and worked for SimH 3.9 and later releases. The SimH 4.* development
over time became incompatible with the `scmd` scripts used for w11 verification.
See issue [#30](https://github.com/wfjm/w11/issues/30) for details.
The bottom line at the moment:
- install SimH from [simh/simh](https://github.com/simh/simh)
- checkout `v3.11-1`

### V0.79 {[issue #30](https://github.com/wfjm/w11/issues/30)} -- SimH scmd files fail on current 4.* version; only 3.* supported
The SimH scmd scripts were originally developed for SimH 3.8, and worked for
SimH 3.9 and later releases. The SimH 4.* development team decided not to
provide releases anymore, and over time this version became incompatible with
the scmd scripts used for w11. That is most pronounced for the RT11 V4.3 oskit.
A simple
```
cd $RETROBASE/tools/oskit/rt11-53_rl
console_starter -s -d DL0 &
pdp11 rt11-53_rl_boot.scmd
```
works fine for SimH V3.9, V3.10 and V3.11-1, but fails
- for pdp11-4.0-beta1 with core dump
- for pdp11-2016-12-26-5ced037b with signal SIGSEGV in pdp11_xu
- for pdp11-2019-07-28-2f707ffc with signal SIGSEGV in pdp11_xu
- for pdp11-2020-03-26-261abfc3 with signal SIGSEGV in pdp11_xu
- for pdp11-2021-08-22-64b12234 with signal SIGSEGV in pdp11_xu
- for pdp11-2022-04-17-d3f1ee09 with with errors like
- Device auto configuration is now disabled
- Command not allowed (for set rha enabled)
- container incompatible with the RL device
Bottom line:
- the provided scmd scripts work only with SimH V3.9, V3.10 or V3.11-1
- an update to the SimH V4.* has low priority
