While not part of the license terms, I would like to ask that any commercial or institutional users who derive benefit from this software consider arranging for a modest support agreement. Without the income from a handful of commercial licensees, it would have been completely impossible to justify the time that went into developing and testing this product. Of course, this software comes "as is" with no guarantees whatsoever, and with ABSOLUTELY NO WARRANTY. This is particularly true for this Distribution, which is NOT the same as the V1.x commercial version; I took the opportunity to make several substantial cleanups and additions which have yet to be thoroughly verified and tested. There are still some known issues with certain platforms, but I've decided to proceed with this release now rather than postpone it indefinitely in the perpetual pursuit of perfection. --------------------------------- Now, if you're the impatient type who wants to get on with it, go straight to: doc/install.txt But if you're the rarity who likes to read everything first, I recommend starting with: doc/Intro.txt Please send me any bug fixes (preferably conditionalized for clarity), as well as any ideas for improving the distribution itself. Undoubtedly there will be many. I can't promise I will be able to incorporate all of them in a timely fashion since my clients and family will always have first priority, but will do my best.

While I am responsible for all of the KLH10 software and documentation as of this distribution, there were many people along the way who, whether they knew it or not, helped make it happen. Everyone who uses this software owes them a debt of gratitude! First, the list from the original KS10 version: Stu Grossman, for convincing me that a C version was feasible. Alan Bawden & Dave Moon, who (apart from their already legendary roles in ITS) helped as much as they could without actually being there. Jay Verkler, who provided a MIT-AI lab environment within Oracle. And everyone else on the ITS-LOVERS and TOPS-20 lists whose messages and actions have helped keep PDP-10s alive. Plus: Mark Crispin, without whom it would never have run TOPS-20. Rob Austein, for lots of network and porting help; the "tun" IMP code is based on his work. Now, for the KL10 version: Andy Riebs and Maurice Marks, who championed the KL project at DEC. Larry Sendlosky, who more than anyone else is responsible for the success of the KL10 version. While at DEC he dug up whatever was needed, built and tested innumerable configurations, and went into the field to pitch and support the emulator. Doug and Christina Engelbart, and the rest of the Bootstrap group, for preserving the SRI-NIC DEC-2065 just long enough. Without a working KL and filesystem it would have been much harder. Duane Winkler, for taking a chance. Bill Parsons, David Alspaugh, Dennis Horn, Holly Sue White, Jim Saleh, Mary Coppernoll, Raylene Pak, Tom Jenkins, Tom Saleh, and many unknown others for using it and shaking the bugs out. And finally: Doug Humphrey, who supported the merge and Public ITS work. Bob Supnik, who made it possible to release the sources. Lars Brinkhoff, for inspiration and release testing. Tim Shoppa, for his preservation efforts and release hosting. If I've inadvertently left anyone off, please let me know. Thanks again! --------------2C9EB37D69F0B2726806E6C3 Content-Type: text/plain; charset=iso-8859-1; name="license..1" Content-Transfer-Encoding: 8bit Content-Disposition: inline; filename="license..1" /* LICENSE - KLH10 License Terms */ /* $Id: klh10.lic,v 2.2 2001/11/10 10:41:40 klh Exp $ */ /* Copyright © 2001 Kenneth L.

The most important thing to know is that this is a MACHINE emulator. It emulates a specific PDP-10 CPU and all necessary I/O devices, running a site's existing operating system (monitor) binary without change -- which then runs user-mode application programs just as if they were on a real PDP-10. Even floating-point results are bit-identical. This means sites must continue to manage the virtual system in the same way as a real one, without the old hardware. However, the emulator doesn't monopolize the actual platform, and runs as a set of simple user processes that co-exist with other software on the native system. It is possible to configure it so that no actual CPU time is used while the virtual system is idle. The KLH10 emulator is extremely portable and flexible -- it is written in ANSI C so that it can be ported to new platforms quickly, and new "virtual hardware" can readily be added. The following describes the currently supported versions: Emulation Target: KL CPU: KL10B with extended addressing Memory: 4MW MF20 (22 bits - 8192 pages of 512 words) Microcode: v.442 (supports final versions of TOPS-10 or TOPS-20) Devices available: DTE - one CTY RH20 - up to 8 (7 if using a NI20) Disk - 8 RP06 or RP07 drives per RH20 Tape - 8 TM02/3 formatters per RH20, with one TU45/TU77 each Network - one NI20 (KLNI/NIA20) ethernet interface Emulation Target: KS CPU: KS10 Memory: 512KW (19 bits - 1024 pages of 512 words) Microcode: ITS v.262 (supports final version of KS10 ITS) DEC v.130 (supports final versions of KS TOPS-10/20) Devices available: FE - one CTY RH11 - up to 2 Disk - 8 RP06 or RP07 drives per RH11 Tape - 8 TM02/3 formatters per RH11, with one TU45/TU77 each Network - one "ACC LH-DH" IMP interface (ITS only) Supported Host Platforms: Compaq/DEC Alpha with Tru64 (formerly Digital Unix, formerly OSF/1) SUN Sparc with Solaris Any x86 with FreeBSD, NetBSD, or Linux Plus: Any system providing equivalents to basic Unix system calls. WNT/W2K ports are possible. Requirements: Memory: KL: 35MB (3MB program, 32MB emulated PDP-10 memory) KS: 6MB (2MB program, 4MB emulated PDP-10 memory) Disk: .2-.3 GB per RP06, .5-.9 GB per RP07, 50+GB per dynamic RPxx Tape: optional, can use any variable-record-length drive Network: optional, LAN interface advised (can share single interface with native OS, but a second may be desirable) Performance: Varies with job mix and platform architecture, but general observations suggest the following ratios relative to a real PDP-10 (where 1.0 = KL10 speed): SPARC: (MHz / 200) Alpha: (MHz / 250) x86: (MHz / 200) Thus, a 450MHz x86 would provide slightly over 2x KL speed. IMPLEMENTATION ============== The KLH10 internals are organized in a fashion roughly similar to that of actual hardware. There is a "KN10" process equivalent to a KS10 or KL10 processor that carries out all CPU operations and is continuously running, except when the KLH10 user-interface command parser has control. Most importantly, each hardware device is implemented as a separate subprocess, with optional direct access to main PDP-10 memory for data transfers. This architecture has several advantages: - It can take advantage of multi-processor host platforms. - The emulated CPU never needs to wait for I/O. This considerably speeds up operation, compared to a non-threaded emulator which must block on disk I/O. - It can directly use very slow physical devices such as magtape drives (half-inch, 8mm, 4mm, DLT, etc). Virtual tapes (i.e. tape images on disk) are also supported. - The sub-process implementation is more portable and robust than a threaded implementation. - Device failures need not be fatal. The NIA20 network device for example can be reloaded and restarted without stopping the KN10 or the TOPS monitor. TERMINOLOGY =========== There are two terms used in the documentation and source that may cause confusion: KLH10 and KN10. "KLH10" refers to the entire software product covered by the license. This is theoretically a proper name ("KLH10 has") but is often used as an object name ("the KLH10 has"). "KN10" refers to the virtual PDP-10 created at runtime by the "kn10" executable image. It is specifically intended to serve as an object name alongside the physical PDP-10s KA10, KI10, KL10, and KS10. Nearly all software products are referred to like people (ITS, Emacs, Oracle, Solaris, etc) and the same can be done with "KLH10". However, to emphasize that it emulates a hardware device, it is often still referred to as an object -- "the KLH10". In fact this objectification urge is so strong that it is actually difficult to avoid using the articles "the" and "a". The term "KN10" was invented to help maintain the distinction between the product and the virtual machine/object. I will let others speculate on why English is this way. --------------2C9EB37D69F0B2726806E6C3-- ###### Sender: phr2001-nospam@ruckus.brouhaha.com From: Paul Rubin Newsgroups: alt.sys.pdp10 Subject: Re: Announcing KLH10 References: <3BED98B8.312D35D4@trailing-edge.com> Date: 11 Nov 2001 04:53:26 -0800 Message-ID: <7x3d3leaex.fsf@ruckus.brouhaha.com> Organization: Nightsong/Fort GNOX Lines: 30 User-Agent: Gnus/5.0807 (Gnus v5.8.7) Emacs/20.7 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii NNTP-Posting-Host: ruckus.brouhaha.com X-Trace: 11 Nov 2001 04:53:29 -0800, ruckus.brouhaha.com Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!enews.sgi.com!news.spies.com!ruckus.brouhaha.com Xref: chonsp.franklin.ch alt.sys.pdp10:7474 Tim Shoppa writes: > While I am responsible for all of the KLH10 software and documentation > as of this distribution, there were many people along the way who, > whether they knew it or not, helped make it happen. Everyone who uses > this software owes them a debt of gratitude! I'm really happy to see KLH10 finally released. Congratulations and thanks to Ken for releasing it. I'd also like thank Tim Stark for releasing TS10, and suggest that new KLH10 users do the same. While there have been several PDP-10 simulators developed over the years, TS10 was the first free one released to the public on a wide scale. The others existed earlier, but stayed unreleased or circulated quietly, maybe because of incomplete development, or perhaps in the hopes of getting some commercial gain from an ever-shrinking market of legacy PDP-10 users, or possibly for some other reason. I think Tim's releasing TS10 opened the way for both Bob Supnik's simulator and KLH10 to be released. The days of the PDP-10 as a commercially viable platform are long gone. It's great that those of us who remember using real PDP-10's can now share and enjoy the simulators. There was no point in holding them back any longer once TS10 was out there. Bob and Ken (and Stu Grossman, author of the mostly unreleased KX10), like Tim, did excellent work programming their simulators, and they all deserve our admiration and thanks. But Tim took the lead in releasing his results to the world and deserves special gratitude. Thanks Tim! ###### Message-ID: <3BEE9CD9.B9C40C6B@bellatlantic.net> From: bad bob X-Mailer: Mozilla 4.75 [en]C-CCK-MCD BA45DSL (WinNT; U) X-Accept-Language: en MIME-Version: 1.0 Newsgroups: alt.sys.pdp10 Subject: Re: Announcing KLH10 References: <3BED98B8.312D35D4@trailing-edge.com> <7x3d3leaex.fsf@ruckus.brouhaha.com> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Lines: 19 Date: Sun, 11 Nov 2001 15:41:09 GMT NNTP-Posting-Host: 138.88.75.218 X-Complaints-To: business-support@verizon.com X-Trace: typhoon2.gnilink.net 1005493269 138.88.75.218 (Sun, 11 Nov 2001 10:41:09 EST) NNTP-Posting-Date: Sun, 11 Nov 2001 10:41:09 EST Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!newscore.univie.ac.at!howland.erols.net!netnews.com!xfer02.netnews.com!newsfeed1.cidera.com!Cidera!cyclone1.gnilink.net!spamfinder.gnilink.net!typhoon2.gnilink.net.POSTED!not-for-mail Xref: chonsp.franklin.ch alt.sys.pdp10:7470 Thanks Tim Shoppa for hosting all this more than an anachronistic interest in PDP10s and data on other PDPs.
