KLH10

Kay Dekker: Added more detail.

KLH10 is a [[PDP-10]] emulator written by Ken Harrenstein. Unlike [[SIMH]], which emulates the KS10 (microprocessor-based) processor model, KLH10 emulates the slightly earlier KL10 processor, allowing large memory systems to run. It was originally considered for a [[NetBSD]] port.

Kay Dekker: General cleanup: typos, layout, etc.

[http://sourceforge.net/projects/simh/ SIMH] ([http://simh.trailing-edge.com/ home page]) consists of simulators for about 20 different machines, and as such, is a very important emulator for anyone interested in computer history, in particular, that of [[DEC]] systems, as the PDPs and even the [[VAX]] are well emulated by it. It can even emulate network interfaces for the [[PDP-10]], [[PDP-11]] and VAX, so the emulated systems can network directly onto the Internet, if the emulated operating system supports it, like BSD or [[VMS]].

SIMH was primary written by Bob Supnik of Zork porting fame, and is now widely contributed to by others as well.

== Emulated Systems ==
=== Altair 8800 ===
This is the Altair 8800 emulator which can run both AltairDOS and CP/M 2.2

=== Altair Z80 ===

SIMH emulates the [[Altair]] architecture with your choice of either a [[Z80]] or [[Intel 8080]] processor. It can run [[CP/M]].

=== HP2100 ===

I really don't know much about this machine, but I included a way to run the basic1 program I found online. It kind of reminds me of the ROMBASIC back 'in the day'... It's basic with line numbers so I know it's kind of old.. I really don't know much otherwise about this machine.

=== Interdata 8/32 ===

The interdata 8/32 micro was the first non [[PDP-11]] to run UNIX. SIMH can run both v6 & v7 research editions for the Interdata.

=== Nova ===

SIMH can run [[RDOS]] 7.5 for the [[Nova]].

=== DEC PDP-1 ===

The original [[PDP-1]] is emulated although most of the software is expected to be toggled from the console, or loaded from paper tape. SIMH does not emulate the display needed for [[spacewar]].

=== DEC PDP-8 ===

The [[PDP-8]] was the first 'affordable' microcomputer... [[OS/8]] runs under SIMH.

=== DEC PDP-10 ===

The [[PDP-10]] model KS processor is emulated and will run all but the latest versions of the [[TOPS-10]] and [[TOPS-20]] operating systems.

=== DEC PDP-11 ===

The [[PDP-11]] is emulated enough to run most PDP-11 operating systems including the early Unixes (v1,4,5,6,7 are known to run).

=== MicroVAX II ===

SIMH can run the [[MicroVAX II]] with as much as 256mb of emulated ram. Both VMS, NetBSD, OpenBSD and original BSD can run on this emulator. Additionally, the network adapter functions correctly under this emulator, unlike the [[VAX-11/780]].

=== VAX 11/780 ===

SIMH can also emulate the first model of the VAX, the [[VAX-11/780]]. This is appropriate for older operating systems like VMS release 1.x and the original 32v, 3BSD and all 4BSD releases.

== Usage ==

SIMH can either take in configuration parameters interactively, or you can store them in a file. If the file is the name of the emulator+.ini it will load them automatically (eg vax.exe loads vax.ini automatically). The CONTROL+E key will break the emulation and bring you back to the SIMH console where you can alter the running state.

Networking is covered in the [[Networking with SIMH]] guide.

While not immediately obvious, there is a mailing list here [http://mailman.trailing-edge.com/pipermail/simh/ http://mailman.trailing-edge.com/pipermail/simh/]. I would recommend searching the thing, and you'll be amazed how much good information there is in there. Likewise, I'd recommend joining the list if you are interested in running SIMH.
