Strange qbus board

by roeapeterson＠gmail.com

I received a qbus board with a small pdp11/23 system recently, and I can't find any info about it with my best googling. It's made by data systems design, copyright 1980, appears to be model 804120-01. Dual-width qbus board, with a 34-pin ribbon cable connector on the top board edge, maybe floppy controller? The only real non-ttl non-rom chip is a AM2901BPC. This seems to be a four-bit bit slice micro... Anyone ever seen this beastie? Thanks.

HP LaserJet Font cartridges needed by anyone?

by mattislind＠gmail.com

With a nice HP85 computer I just got there were two HP 92286K MATH TMS font cartridges included. I have no idea why. Myself I have no compatible printer. Does anyone want the font cartridges? Free for cost of shipping from Sweden. I save them for a couple of months then I toss them if there is no interest.

22-bit ECO for REV11 [AKA TEV11] (M9400)

(On > the BDV11, there's a resistor pack with 4 unused pull-up/down pairs So I located a set of prints for the TEV11 (which I must scan and get to Al, they don't appear to be available online), and on the M9400 there are four spare pull-up/down pairs, although not all in one package. They are: E6-1 E17-1 E17-12 E27-15 I have verified that these are free (looked at a board, no traces to those pins). (And yes, the 1 pin is usable - it's used in E27.) Not all in the same package, so the ECO will be a bit messy, but it can be done. Guess I should read out the ROMs, too (assuming they haven't already suffered bit rot). Noel

C, please die, and take Go with you - Re: Fwd: is there any word processing software for the pdp11?

> From: Al Kossow <aek at bitsavers.org> > People traded safety for speed, and thanks to the net and cowboy > programming, that has turned out to be a bad decision. Pshaw. C is only as unsafe as you make it. It's not the language that has caused, for example, Internet security issues - it's programmers who refuse to learn well-known lessons like "always, always, *always* bounds-check network-facing buffers *no matter what*" that give us things like Heartbleed and any number of other overrun/underrun/etc. vulnerabilities. Blaming the language for the badness of bad programmers is like blaming the chainsaw for the actions of some nitwit who decapitated himself playing with one.

RUNOFF was Fwd: is there any word processing software for the pdp11?

by tshoppa＠wmata.com

DEC sold WPS-8 which ran on PDP-8's, which was kinda WYSIWYG (rulers etc), but I don't know of anything quite up the WYSIWYG alley for the -11's. Most common on an -11 was a basic text editor plus DECUS runoff (which most often just formatted for a line or dot matrix printer). DECUS runoff for the PDP-11 (at least in late 70's was under the DECUS text processing SIG) is obviously a reimplementation of most common features of PDP-10-ish DSR . I don't know if DEC ever officially had DSR for the PDP-11. DSR = "Digital Standard Runoff". DECUS runoff has a lot in common with DSR and the other "classic" runoffs but I've never done an actual entymology to see what is unique and what is common between them for a lineage. I myself have re-implemented runoff in Perl a couple of times. It is completely trivial in Perl. Tim.

36bit still in use ?

by rhirst＠xkl.com

I'm Roy Hirst, a hobbyist new to the list - today is my day 1 - and I currently work for XKL LLC. I'd like to contribute where I can to this and other conversations on cctalk. XKL makes a line of optical networking systems, think 10x10GE in 1RU. A system has two planes, a (1) traffic plane where client equipment (e.g. "server") traffic gets aggregated to DWDM channels on a single optical fiber, and (2) a management plane that, er, manages remote config, real-time failover, OS field upgrades, etc. The planes are independent and you can reboot the OS after an upgrade without affecting packet traffic. The emphasis is on reliability, resilience, configurability,. We have had DWDM systems running 5 years without incident using these backplanes. The TOAD-2 is looked back on here with affection, some of the original architects and engineers are still around, and memory systems and interfaces have been under continuous development and extension since TOAD-2 days. I am not sure if you used to work here you would recognize it now. Is still 36-bit,? Yes.

I used that PDP-1 at MIT in 1972 or so for the 6.273 programming course. Still have my class notebook, with all my programs printed out on the Flexowriter terminals. That PDP-1 was not a 'virgin' PDP-1 any more even then, it had features added by eager grad students. As indicated above the second / backup that CHM has would be a better choice to restore.

Random DEC Questions

by robert.jarratt＠ntlworld.com

I just collected a nice little "haul" of DEC gear yesterday and have some questions: One of the things I got was an RA60 drive. But it doesn't have any packs. Does anyone in the UK have any RA60 packs they would be willing to part with? I also got a VT320, but it looks to be a 100-120V model. Is it possible to convert these easily to 220-240V? I discovered that there is a little MMJ to RJ45 adapter called a H8584. I know I can make cables that would remove the need for these, but they look quite handy. Anyone in the UK have any of these spare? I got a DECserver 900TM (see earlier thread about WWEN2.SYS). Manx has an installation manual on it, but not a detailed operations manual. I don't have the Flash RAM card which I guess is needed to persist the boot image without having to boot off the network. Does anyone know what kind of card it needs? I am told it is a CF card, but it looks like it needs some kind of holder to hold the card, and I don't know how the image would get onto the CF card, unless it does that itself after loading from the network.

No such thing as "the PDP" [was RE: Typesafety versus Worse is Better - was Re: Fwd: is there any word processing software for the pdp11?]

by RichA＠LivingComputerMuseum.org

From: Mark Wickens Sent: Thursday, December 04, 2014 12:47 AM > Has anyone considered whether it would be possible to port lua to the > PDP? You know, there never was (or only for a very short time) such a thing as "the PDP". DEC produced systems with 5 different architectures (or 4.5, if you lump the two 18-bit architectures together; I usually do) under the rubric "PDP-<small integer>": The PDP-1, the PDP-4/7/9/15, the PDP-5/8 family, the PDP-6/10 family, and the PDP-11 family. I would argue that only the original PDP-1 could rightly be called "the PDP", but even then, DEC had designed the 24-bit PDP-2 and the 36-bit PDP-3 which they did not build themselves, for a total of 7 architectures designated "PDP". Back when I was doing sales support for XKL, a lovely lady who did consulting in the oil industry advised me that we should be selling the Toad-1 in that market "because there are PDPs *everywhere* in the fields!"

Wanted: Twinax 5250 Style Terminal

by Kevin＠RawFedDogs.net

Classic Computer Enthusiasts, I should have an IBM 9406-270 arriving today or tomorrow. I think I've gathered everything I need to attempt an OS install except a console. I do have a second NIC that I've been told could be used for console access. But I suspect special console software would be required to do so, and all my PCs at home run Linux which would probably complicate things. I've also been told that when using a NIC for console access there are several gotchas to watch out for, such as a specific slot requirement for the NIC, etc. This being my first attempt at installing an OS on a 9406 anything that can be done to simplify the process and avoid having to worry about gotchas is probably a good thing. Plus, I like twinax terminals, especially the keyboards. So, does anyone have a suitable terminal in need of a good home? There are a few available from eBay, but I hate to pay more for a terminal than I did for the 270. I'll probably also need the multi-port twinax connector block that connects to the twinax card in the 270 if anyone has one to spare. There wasn't one listed in the eBay list for the 270, but I might get lucky and have it arrive with one included. -- Kevin http://www.RawFedDogs.net http://www.Lassie.xyz http://www.WacoAgilityGroup.org Bruceville, TX What's the definition of a legacy system?

Scanning MACRO-11 Manual

by jnc＠mercury.lcs.mit.edu

> From: Johnny Billquist >> a copy of the "PDP-11 MACRO-11 Assembler Program Manual" >> (DEC-11-OMACA-A-D). > What do that manual contain? The PDP-11 MACRO-11 Language Reference > Manual is certainly online. (AA-KX10A-TC) That and a host of predecessors, going back to the "MACRO-11 Language Reference Manual", AA-5075A-TC, 1977-08: http://manx.classiccmp.org/details.php/1,5565 This one is fairly older; the date on it is April, 1972. Compared to the one above, this one is missing that one's Chapter 1 ("MACRO-11 Features"), this one has a different Chapter 1, "Fundamentals of Programming the PDP-11", covering topics like "Modular Programming", "Commenting PDP-11 Assembler Programs", "Localized Register Usage", "Conditional Assemblies", etc, etc. Past that, they seem to be pretty much the same, until you get to Chapter 8, "Operating Procedures", which is missing in the later one. This one has an Appendix D, "Listing of SYSMAC.SML" which is missing in the later one, which has an Appendix E, "Sample Coding Standard", which this one lacks. So not too many differences. Whether this is worth having online also, given that there are numerous later versions ... dunno. Opinions? Noel

Can you ID / document this RS-232 to Current Loop converter?

by drlegendre＠gmail.com

Hey gents, I tried the greenkeys list, but to no avail. So let's see who knows what around here... I recently acquired a pair of these RS-232 -to- CL converters. They are branded "ED&M" or possibly "EDeM" - but they seem to have been made by an outfit called Camiacs. They are marked Model V or Model 5. The circuit boards are marked "CAM 25-116A" in one corner. Photos can be seen here: https://nerp.net/~legendre/greenkeys/rs232_cl_converter_01.jpg https://nerp.net/~legendre/greenkeys/rs232_cl_converter_02.jpg Does anyone have documents for these units? They have several sets of internal jumpers, to configure various RS-232 parameters as well as passive / active states for the current loop side - Rx+ / Rx- Tx+ / Tx- etc. Any ideas? Any documents? Thanks in advance!

Fwd: is there any word processing software for the pdp11?

by jnc＠mercury.lcs.mit.edu

> From: Rich Alderson > The first non-PDP-10 port was written in MACLISP for Multics--a 36-bit > architecture!--by Bernie Greenberg Depends on what you define as 'EMACS'... :-) The PDP-11 TECO with real-time display mode which I was talking about earlier had, when in real-time mode, a command on every single control character, most of them the same as EMACS. (E.g. typing ^U^K would kill 4 lines, from the point onward.) And you could write custom code for it. (In TECO, no less!) But it didn't have the rich command set of EMACS (although as of that date, EMACS was still in a bit of flux - many people still had their own private macros/command sets - MOON's was famously different). According to: http://www.multicians.org/mepap.html (which is a very nice, complete, history of Multics Emacs, BTW), Multics Emacs didn't run until March, 1978; the PDP-11 real-time display TECO was running well before that. (We all used ITS some, for ARPANET email, etc, so we wanted the same kind of powerful editing tool.) Not that it really matters any more - just trying to be historically accurate! > From: Jerome H. Fine > Since the "Subject" specified "word processing software", I assumed > that would exclude TECO which I regard as a "text editor" Two words: 'topic drift'! :-) Hey, just responding to other messages (e.g. above). > From: Chuck Guzis > DIBOL. :) Hey, if you're running one of the later 11's, the ones with CIS, reputedly DIBOL runs _really fast_ on them!

Yay, now I need some Osborne boot media!

by drlegendre＠gmail.com

Thanks to the efforts of several members, my Osborne Vixen is up & running with a working display. But now the dang thing is begging me for a disc that I don't have.. =/ Could someone possibly send me some boot-media for this machine? As things sit, I don't even have a PC with a 5-1/4" drive installed, if (and that's +if+) it were capable of writing discs for the Osborne format. I've tried feeding it media for Epson & Kaypro CP/M machines, but no dice - it rejects them without a second seek. Anyone know how to handle this?

36bit still in use ?

by jacob＠dahl-pind.dk

Given the certain overlap of interests some of you might have seen this, please bare over with me. On the talk of copyright status on TOPS-10/20 on the hecnet maillist, it was hinted at tops-20 where used embedded for routers from XKL, running on reimplemnted pdp10 hardware. <qoute> Unfortunately I do not have much details. I was at the Living Computer Museum and talked with RIch Alderson, who used to work at XKL. And he showed me a newer generation router from XKL, opened up, at LCM. And they use a PDP-10 on a chip, and it was actually running TOPS-20, and I could play around at the EXEC level in there. </quote> Findes it somewhat hard to imagine anyone would take 36bit architectur and build a router around it. But it does seem posible they really do, I visisted ftp://xkl.com/pub/download/ tar xvf DarkStar_v3.0.0.tgz and looking in upgrade-example.txt I sees things as System Processor (XKL-2) 2. XMH-1 (256MW), Testing: SDdAa, on line at LPN o0 Reading 0704 pages 0704000 words read in 36 bit mode .. Its alive! who would have though that -- Jacob Dahl Pind | telefisk.org | fidonet 2:230/38.8

Defeated by a Commodore 1950 Monitor

by nf6x＠nf6x.net

I have a Commodore 1950 monitor that came along with an Amiga 3000, and I think it has defeated me. Its failure mode is that there's no vertical scan; just a single, horizontal line. Vertical drive is still working, because I can shift the line up and down a bit using the vertical centering control, but whatever circuitry generates the vertical scan doesn't appear to be doing it. Trying to debug it has been challenging, even though I found a service manual online. The monitor appears to have been designed to be slapped together without much consideration of service accessibility, and the service manual does't describe the circuitry in much detail. It includes a block diagram, with no indication of which actual circuitry corresponds to which blocks. The schematic diagrams show connectivity between the parts, but don't identify the functionality of most of the ICs. I think I've narrowed down to one IC that's a likely candidate for the failed component, but it's still just an educated guess that it's even the IC responsible for generating the vertical scan. And it's a no-name IC with the monitor manufacturer's internal part number (IC401, with part number 56A326-1), so I don't think I'm likely to find a replacement for it unless I find another model 1950 with a different failure. I have an LCD monitor that I can use with the A3000, but the A3000 just doesn't look right with a flat panel on top of it. Now I wish I hadn't gotten rid of my old Viewsonic 17" CRT monitor all those years ago! I was sure happy to see it go at the time, but I failed to predict that I'd get interested in retrocomputing a decade later. So, I guess I'll just keep my eyes open for a suitable CRT monitor that I like for the A3000. Maybe some older Viewsonic monitor in the 13"-17" range? If anybody near southern California might be able to use my failed 1950 for parts, or has a 1950 with a different failure that they'd like to dump on me, please let me know! Even though I don't anticipate being able to fix it, I don't want to throw it away, in case parts appear or some other collector can make use of it. So, I'll stash its carcass away for the time being. -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

Weird 8-inch floppy disk

It's clear that they're hard-sectored, but the index and sector holes are along the outer edge. There's also a notch cut into the corner. Both of these appear to be done in an attempt to restrict users to a single vendor of floppies.

Whitechapel Computer Works MG-1

3M "WhisperPrinter" (Trendcom 100) docs?

by derschjo＠gmail.com

Picked this up for nearly nothing at a local recycler, it was too cute to pass up. It's a 3M "WhisperPrinter" (model 1904AA), and it's a small (40 column, 4.5" wide) thermal printer with a serial interface. It appears to work (runs a self-test if you hold the line feed button while powering on) but I don't know what the pinout for the interface on the rear is (it's a 20-pin header). This looks to be a rebadged Trendcom 100 (which I can also find very little technical info about) used on a number of early home computers (Atari, TRS-80, PET). Anyone happen to have a manual for this? Thanks, Josh

Summary: is there any word processing software for the pdp11?

by jacob.ritorto＠gmail.com

I was seeking the "best" pdp11 prose text editing experience for typing in manuscripts, composing, letter writing, etc. (not programming language - that was just a side effect of some editors actually being programming languages in and of themselves). Since this is such a highly relative subject, I expected a slew of answers and got them (thanks, all!). While not part of the originally-intended scope, the conversation has inspired me to at least try composing in TeX, which I've sort of meant to do for years, but never got a round tuit. Sounds like it'll stay out of my way and allow me to just flow ideas and not even address layout until the end, which is, in essence, what I'm after. That said, I think the most convincing answer to my original question so far, not having actually reviewed them yet, is some kind of emacs, most likely Jove since it's already there in 2.xBSD and keeps me from having to mess with/re-learn other operating systems (oh, shoot!). As a side note, I used teco and edt back when pdp11s running DEC operating systems were still being phased out and found them to be unsatisfying; however, I do admit that I was an amateur at them. My other point here was to get the Diablo 630 going and have it type nice, letter-quality copy for me. Since my kid had a report due this morning, I caved and temporarily connected it to an old Sun machine and just threw lpd at it. Pretty straightforward: lpadmin -p diablo -v /dev/cua/b -o stty=300 -o banner=never enable diablo accept diablo So the thing's up and accepting jobs. Prints like a war zone :) !!! Once one of the '11s is up, on the net and stabilized, I'd like to have it take over this role as well. thx again for all the discussion around this & feel welcome to continue the thread! jake

Does anybody know if it is normal for a TM-848E to spin up for a few seconds after getting power and then stop spinning. The only other 8" drives I have experience with seem to start spinning when power is applied and keep spinning regardless of if the door is latched or if there is a disk in there. Thanks.

Nat Semi ns32k, was Re: Whitechapel Computer Works MG-1

by jnc＠mercury.lcs.mit.edu

> From: Steven M Jones > only to be pummeled by the emerging RISC designs... My (dim) recollection of the NS32K architecture (I recall someone came to MIT and gave a presentation on it, and I have an early architecture document - so old that it's called the NS16K!) was that it was very elegant, but my sense now, looking back, was that it was one of that wave of machines (the VAX being the other notable one) that went down the CISC road just before RISC arrived, and showed that CISC was not really the way to go; those systems were all dinosaurs. Which, in the NS16K/NS32K's case was unfortunate, because the architecture in other ways, i.e. at a high level (i.e. ignoring the instructions), was the best of the whole lot. Notably, it attempted to provide real segmentation support, perhaps the only chip of that group to do so. Although of course once Unix took over the world, that was irrelevant. (Much as I dearly love(d) V6 for how it got an incredible amount of power out of a very small machine, it's pretty clear that the basic approach of Unix was inferior to that of the single level store systems [e.g. Multics]; Unix really was - and in many ways remains - a toy operating system, considered >from a larger viewpoint.)

IBM Series/1, PDP-11/84 potentially available in Oregon

by kd7bcy＠kd7bcy.com

I'm looking at clearing out my basement a little as my old computer interests and space requirements change and am considering getting rid of part or all of my Series/1 system. It has never been operational while I have had it, and was originally wired up for 240v operation - although the CPU and small tape drive were re-configurable to 120v by a jumper, and I did power them up together shortly after obtaining the system, but didn't have any OS or software to run on it. I have one IBM rack, which I am willing to part with if the whole system is going, otherwise all my network gear and newer servers are going into it(it's only 6' tall so it fits well in my basement. I have a 4967-K00 CPU, a 4968 tape drive, an unknown model Cipher tape drive(very large), one or two 4959 expansion units, maybe a broken 8" floppy drive if I still have it. I also have two terminals and a lot of cabling for them in unknown but presumably poor condition, currently coiled up in the back of the basement on the floor. I should also still have a decent pile of expansion cards, most of them communications, some of them disk controllers. And hopefully enough interconnect cabling to be useful. Now for the really ugly part - I do indeed have some binders with information on some of the units, and probably some stuff that isn't there, but we had a water leak a while back and some of it was water damaged. I put them aside but never had time to attempt anything with them. I do have a picture of part of the system and the rack... The Cipher is sitting under the 1U server at the bottom of the pic. And one of the terminals with keyboard is visible sitting on top of the PDP-11/84. They've both been buried in the basement behind storage boxes for a while. http://www.kd7bcy.com/images/comp/oldracks.jpg On a side note, the PDP-11/84 may also be available soon. It's pretty bare bones and will likely need at a minimum a disk drive and controller. I used to have a list of the cards that were installed but I can't find it right now. I have a disk drive of some kind in the garage currently, I think it's an 8" floppy drive but I haven't looked at it closely, and it is in poor shape. The CPU rack in the basement is decent, just a broken spot weld on the door hinge which makes it hang loosely. Similar story to the Series/1 - never got it operational, but it was powered on long ago when I obtained them during initial investigations and testing. Other than the drive that I picked up at a local surplus store I have nothing that goes with this, maybe an old DEC paperback book of some kind if I can find it. I'm tempted to put it on eBay after seeing the price the last one sold for, but would be happy to entertain offers from this group first(interesting trades are always welcome). I should have some random DEC boards of some kind laying around as well. I know I've posted about both of these systems in the past on this list, over a decade ago. I was hoping to get this one up and running in a meaningful way but just never had the time or money to put into it. The IBM is pretty much free to anyone who wants it, picked up at my house in Portland, Oregon, USA. Time frame is pretty loose, it's not like I need these out immediately, and it will probably take a couple of weeks to round everything up on weekends and get the cobwebs cleaned up, but I won't be sitting on these a terribly long time either. I imagine I will probably start dumping unwanted stuff by other means by late February. Parts are spread all over the place, so it may take a weekend or two to get everything together and moved up to the garage for pickup. I kinda like the rack, so if you don't need it I can keep it, or if you have a spare rack 38U or shorter to swap that would be great. If no one wants it, I will likely keep the CPU and tape drive in the rack and scrap the rest of it. The Cipher looked pretty generic, it may be able to hook up to other systems. If no interest in the whole package or it is unwanted I will make it available separately. If there is interest in one or more systems I will begin moving things to the garage and making a more accurate catalog of what is actually present and a better idea of the current condition of individual pieces. A bit of a wall of randomly wandering text, but there it is. Cleaning out the basement can be such a tedious job! tl;dr - PDP-11/84 and IBM Series/1 available in Portland, Oregon, local pickup required. ------------ John Rollins | KD7BCY | http://www.kd7bcy.com Ham-Mac mailing list http://mailman.qth.net ------------

SMD replacement options?

by earl＠baugh.org

An update on the SMD replacement options... Contacted someone at MBI (mbiusa.com) and they quoted $395 for drive... (I had asked them about a "modern replacement" for the Fujitsu drive in my Sun 1 drive assembly... what they quoted me back was an actual replacement Fujitsu drive... not sure if it's NOS or refurbished OS) Then I clarified my question and said "what's the price for the SMD emulator they had on their site... what I got back was : "The cost of the SMD emulator starts at approx $8500 per spindle, depending on the system spec and controller" (the other ones that I got a link to from a few folks on ebay start at $1500) So, that's a dead end. I can't believe someone hasn't built some sort of adapter from <Modern-Something>-to-SMD that isn't ridiculously priced... Earl the Squirrel

Although it had been hacked locally. After briefly glancing at the sources (see the KLDCP; directory, and IOELEV > in SYSTEM;), it was a real kludge; the IOELEV program ran in _both_ the DL10 -11, and the console -11. (In the latter case, along with KLDCP!!) There was some stuff attached to the console -11 too, apparently; a bunch of serial lines on DH11's. > ISTR a disk farm labeled "Moon's Laundromat" Yes, but I don't think that was on MC. I vaguely recall that it was on a bunch of drives which were mounted in vertical pairs, which must have been CalChomps, which I think must have been the original AI? (IIRC, both ML and DM had DEC RP drives.) Noel

by jnc＠mercury.lcs.mit.edu

> From: John Rollins > I'm tempted to put it on eBay after seeing the price the last one sold > for If you're talking about the one that sold a couple of weeks back for $1K, note that that included a TM80 tape drive (the bulk of the value), and two 11/84s. By the time you deduct the value of the TM80, and the value of the boards which one could easily pull and sell separately (e.g. the CPU and memory, along with the TM80 controller), and the power supplies, the value of the rest works out to... -$0.

bigger pdp11 terminals! (was: is there any word processing software for the pdp11?)

I want to do something like this to 2.11bsd's window(1) utility; possibly vi(1) too.. Window(1) dies with "Out of memory" if you increase the terminal geometry even a little bit.

M1705 dual 12-bit output info

by jnc＠mercury.lcs.mit.edu

> From: Kyle Owen > The block diagram in the Logic Handbook shows a few select jumpers, but > does not give a detailed list of the 32 jumpers, if I counted correctly. Yeah, I noticed that; there were no jumpers shown for the device code. I can only assume that they are similar to the device code jumpers for the M1703. If so, that would be 24 jumpers right there. (It's '24' because the M1705 includes two completely separate devices, which can apparently be given device codes independently.) If so, that would be all of them - the block diagram shows 8; 24 for device codes; total 32. Odd the way they use separate jumpers for 1 and 0; why not one jumper with a pull-up/down? Noel

Cyber ECL Wiring

When I left the project, they were trying to defelop a machine to automate the wiring. It was not going well. The earlier 6000, 7000 machines used twited pair with taper pins.

I sometimes get bored typing on these relatively > snazzy computers we have these days and wish to go back to the way > things were. Ah, got it. I don't know if (on the Unix path) nroff is any good for you; with a good macro package (pretty much essential; raw roff/troff is kind of like raw TEX), it's pretty easy to use. The thing is that 'back in the day', the whole 'WYSIWYG' editing model didn't exist until Bravo on the Alto. (At least, not that I know of - if anyone does know of such, I would love to hear of it.) Except for plain ASCII files, of course... So I'm not sure that if you're looking for 'text mode WYSIWYG', you'll be able to find much. > From: Warner Losh > There was also a TECO version available for the PDP-11's running RSTS/E > (and likely others) There was a 'visual TECO' running on the V6 Unix at MIT; that's what we used before the EMACS came along.

M1705 dual 12-bit output info

by kylevowen＠gmail.com

I've got a couple M1705 dual 12-bit output cards for the Omnibus. Does anyone have schematics or programming information available? I checked bitsavers, but I didn't see anything in the obvious places, and without an option number (like DR8-E for the dual 12-bit I/O card, M863), it makes searching a bit more difficult. I'm hoping to have this controlling my Christmas tree lights this year if I can get something working. It has quite a number of jumpers, and although I can deduce a few must be addressing, I don't know what the others might be for. Any help would be appreciated! Kyle W4GNU

VAX/VMS Software Source Book, 6th Edition (Oct 1990) PDF, Programming in VAX Fortran PDF

by mark＠wickensonline.co.uk

I've just scanned the 1000-odd page software source book for VAX/VMS, 6th Edition from October 1990, available from my scans page: http://wickensonline.co.uk/app/index.html#/scans This is a mammoth book (beware the 643MB download size!) but is a fantastic example of just how pervasive VAX and VMS were. It contains a comprehensive listing of software available for the platform both from DEC and independent software houses. Interesting personally is the indication of programming language used. I've also uploaded Programming in VAX Fortran (Sept 84): I wasn't aware of an online copy of this manual. It's a very handy guide to programming in Fortran that covers everything you'd need to get up and running with the language under VAX/VMS, including the use of EDIT, compiling, linking and debugging, as well as reference material on the language and supporting libraries. Enjoy, Mark.
