I've read this in the "TSS8 Monitor Manual": "In those TSS/8 systems having a local connection to a PDP-10 Time-Sharing System or a Synchronous Data Communication System (Type 637), the input to the user's input buffer and program output is scanned for the character sequences CTRL/B CTRL/X and CTRL/B CTRL/Y, resèctively. All characters up to the next CTRL/B are diverted to the PDP-10 or 637 System, whichever the case may be. Characters from the PDP-10 and 637 System are directed into the user's input buffer." Interesting. I have some questions about it: * How can be emulated one "Local Connection" in both PDP-8 and PDP-10 simulators (I think in SIMH) ? * Anybody saw anytime one of these ? * What it could requires to do in TSS/8 and TOPS-10, by example ? I think this could be a funny thing, and even could open other possibilities. I've heard one time that some PDP-10 systems used one PDP-11 like main console or so. Right ?

I'm not sure what this blurb is talking about. Which user input buffer? The job on the -8 or the job on the -10? Other people may have ignored your post because it's a tad confusing. > >Interesting.

You might try to read up on ANF-10. Another key to use in your google search would be DC72, 680/I. Those were PDP-8s that were used as a comm device for terminals. There may have been a printer off the DC72. >I've heard one time that some PDP-10 systems used >one PDP-11 like main console or so. Right ? There was an -11 tightly coupled to all KLs. There was also comm gear that could be hooked up (lookup DC76). With the advent of DECnet Phase II, there was the MCB which was an -11 dressed in Bliss clothing. /BAH Subtract a hundred and four for e-mail. ###### Newsgroups: alt.sys.pdp10,alt.sys.pdp8 Subject: Re: Local Connection Between one PDP-8 and one PDP-10 and TSS/8 From: jeverett@wwa.DEFEAT.UCE.BOTS.com (John Everett) Organization: Everett Associates X-Newsreader: WinVN 0.99.8 (x86 32bit) References: <9rbjpb$1p5$2@bob.news.rcn.net> MIME-Version: 1.0 Content-Type: Text/Plain; charset=ISO-8859-1 Lines: 37 Message-ID: Date: Fri, 26 Oct 2001 14:19:15 GMT NNTP-Posting-Host: 206.133.124.29 X-Complaints-To: abuse@verio.net X-Trace: ord-read.news.verio.net 1004105955 206.133.124.29 (Fri, 26 Oct 2001 14:19:15 GMT) NNTP-Posting-Date: Fri, 26 Oct 2001 14:19:15 GMT Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!newsfeed-zh.ip-plus.net!news.ip-plus.net!Amsterdam.Infonet!News.Amsterdam.UnisourceCS!news.telia-iberia.com!out.nntp.be!propagator-SanJose!in.nntp.be!news-spur1.maxwell.syr.edu!news.maxwell.syr.edu!newsfeed.cwix.com!sjc-peer.news.verio.net!news.verio.net!ord-read.news.verio.net.POSTED!not-for-mail Xref: chonsp.franklin.ch alt.sys.pdp10:7292 In article <9rbjpb$1p5$2@bob.news.rcn.net>, jmfbahciv@aol.com says... > >In article , > spedraja@ono.com (Sergio Pedraja) wrote: >>Hello.

TSS/8 used CTRL/B as a break character in character streams to divert the next character to the operating system's command interpreter. When we (Don Witcraft and I) designed TSS/8 we wanted to be able to pass character streams to the PDP-10 Monitor (it hadn't yet been named TOPS-10 at that point), thus didn't use CTRL/C as the primary break character. One by-product of the design was that the TSS/8 equivalent of CTRL/C on the -10 was CTRL/B,S; "S" telling the operating system to STOP the running job. The first time we demonstrated TSS/8 to KO, SO, and some of the other senior execs, they were typing CTRL/C to it. We told the to use CTRL/B,S instead. KO replied that they'd been trying to control BS for years and was happy to see we'd implemented a way to do so. -- jeverettwwacom (John Everett) http://www.wwa.com/~jeverett ###### From: Arthur Krewat Newsgroups: alt.sys.pdp10 Subject: Re: Local Connection Between one PDP-8 and one PDP-10 and TSS/8 Organization: Kilonet.net Lines: 16 Message-ID: <3BD97644.DE715C2E@bartek.dontspamme.net> References: <9rbjpb$1p5$2@bob.news.rcn.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Mailer: Mozilla 4.78 [en] (X11; U; SunOS 5.8 i86pc) X-Accept-Language: en Date: Fri, 26 Oct 2001 14:47:51 GMT NNTP-Posting-Host: 24.186.100.134 X-Trace: news02.optonline.net 1004107671 24.186.100.134 (Fri, 26 Oct 2001 10:47:51 EDT) NNTP-Posting-Date: Fri, 26 Oct 2001 10:47:51 EDT Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!newscore.univie.ac.at!newsfeed.online.be!64.154.60.72.MISMATCH!cyclone2.usenetserver.com!usenetserver.com!news01.optonline.net!news02.optonline.net.POSTED!not-for-mail Xref: chonsp.franklin.ch alt.sys.pdp10:7283 jmfbahciv@aol.com wrote: > > You might try to read up on ANF-10.

In high school, BOCES LIRICS had a KA10 with a special PDP-8/i front-end from DCA - their own serial boards for terminals. Fastest front-end I ever saw on a PDP... My friend who worked there when I did still has the PDP-8/i in his basement.

I don't know you was one of the persons that designed this OS. Good job, mostly thinking about the size of the memory of one PDP/8. I have some matters related with the emulated hardware environment where I am running actually TSS/8. I'll explain it with the hope somebody can answer me: 1) The machine emulates four KL8JA (or at least four serial ports; I suppose this board has only one serial port and then we have four boards) like additional terminals. 2) It's emulated too one KL8E like main console. 3) Both terminals and console appears to have attached one KSR-33 teletype. That is, it appears that you can't select another terminal type, like one VT05 or VT52. 4) In the TSS/8 manual appears a reference to PT08's. That is the interface for the ASR33 teletype. Right ? 5) The manual says that can support up to 32 "teletype controls" (PT08's or 680/I). It speak too about support for one DA10 Interface, and one Bit Synchronous Communication Unit (Type 637). About the 680/I, the manual says it's divided in one DL8/I Data Line Interface and one Serial Line Multiplexer Unit 685. This is the description of the Hardware that could be used by the TSS/8. With independence of the additional emulation possibilities that it offers, here comes my question itself. 6) In case of PT08's... How works this board ? How much boards could be plugged in one PDP/8 ? What manner ? Must the boards plugged in one additional cabinet with nothing special ? Are they only used to manage the ASR33's ? Where can be located documentation about these units ? 7) About the 680/I and its components... Is there a photo of this unit ? What was the DL8/I ? A board plugged in the PDP8 itself ? What was the aspect of one Multiplexer 685 ? Can be sufficient to emulate one DL8/I to make "think" the TSS/8 that he has one 680/I connected ? Where can be located documentation about these units ? 8) Where can be located documentation about the DA10 interface ? What was this unit ? A board plugged in the PDP8 ? 9) FInally, it's the Sync.Comm.Unit 637. What do exactly this unit ? How treat it the TSS/8 ? Where can be located documentation ?

I have in mind the SIMH emulation of the PDP-8/E. It emulates one KL8E and four KL8JA, with KSR-33 everyone. If I understand good, don't worry to have for my purposes KL8JA's or PT08's. The unique difference appears to be that one supports KSR33, and the PT08 the ASR33. Right ? Could be needed to emulate the PT08, KL8JA, KSR33 and ASR33 in different ways ?
