Update re: Bill Godbout

by cctalk＠snarc.net

I communicated with the person who posted on alt.folklore.computers. The person is a close relative of Bill's; thus, the information about his tragic passing is true/confirmed. The person added, "He was living in Oreville, California and perished in his home on Thursday, Nov. 8. ... Bill was a great man, and THE smartest person I've ever known." Please do not disturb the AFC poster as they're in mourning. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan at vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation

Another IC I Can't Identify

by robert.jarratt＠ntlworld.com

I am still working on the causes of a Reset on my Pro 350. One 8-pin DIP chip that I have traced to is marked as follows: 9643TC-B1 F 8313 KOREA It is very close to the F-11 chips at the bottom left and marked E135 in this picture https://rjarratt.files.wordpress.com/2018/10/system-board-labelled.jpg Can anyone tell me what this is?

Font for DEC indicator panels

by jnc＠mercury.lcs.mit.edu

> We're just about settled on the format for the QSIC RKV11-F/RPV11-D > panels. PS: Here's the latest rev of our thinking: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/jpg/inlay-rk11-f3.pdf if anyone has any comments. (Since the format is entirely set by the FPGA, it's 'easy' to tweak it, if there's a desirable improvement.) It's not the same as the old DEC RK11-B/RK11-C or RP11-C inlays, in part because we want to be able to show the address, and on a QBUS machine, that's 22 bits. Also, many of the fields don't apply to the QSIC (e.g. internal drive signals, 36-bit data buffer on the RP11, etc); we figured it would be better to recycle those lights for something useful (e.g. the address and word count).

IP address classes vs CIDR (was Re: Reviving ARPAnet)

by jnc＠mercury.lcs.mit.edu

> From: Eric Smith > which would respond to ARP requests for non-local addresses and reply > with the router's MAC address (on that interface), specifically in > order to make classful-only hosts work on a CIDR network. Yeah, Proxy ARP (an early RFC here: https://www.rfc-editor.org/rfc/rfc1027.txt but IIRC it was people at CMU who first came up with the idea; this RFC is >from people at UT-Austin, documenting it) was originally done to support subnetting (see https://www.rfc-editor.org/rfc/rfc917.txt for more) when it was first introduced - for hosts for which people didn't have the source, but needed to attach it to a subnetted network. Subnetting was a stage before CIDR (which took subnetting and Carl-Herbert Rokitansky's 'supernetting' and mushed them together). Noel

New to System/36

by alan＠alanlee.org

Just picked up an IBM System/36 5362 tonight. It is in pretty good physical condition with just a few minor scratches - other than needing a thorough cleaning. It has 2 60 MB hard disks in the unit. Not sure of the RAM capacity. Missing the the mode hard key. A few of us tried to get it running tonight. It came with a 3179 twin-ax terminal but no keyboard. We connected the terminal via a twinax cable direct from port 0 to the terminated Y adapter on the terminal. Never got any output on the terminal at any time other than the fairly empty status line. The S/36 front panel console light did illuminate after we connected the terminal. The key was locked to Normal but we were able to by-pass it with a jumper to get it into Service mode. The media that came with it only had disk 1 of an SSP release and we could not get that to IPL from floppy (mode 3 / panel 1000). It stepped the head motor forward and back a couple times, engaged the head, then immediately threw an error code. Any idea where I can get an SSP release for the S/36 5362 and how to write it to 8" floppies? Also where I might find a keyboard for the terminal and what can be done if anything to gauge the health of the hard drives? -Alan H.

NeXT Monitor Problem

by kylevowen＠gmail.com

I've got a NeXTstation Turbo and a MegaPixel display; the computer boots fine, but seems to complain of a failing hard drive. The monitor works okay; slight burn in, but otherwise looks okay in terms of the phosphor. However, something seems to be wonky with the horizontal scan...the left edge is very wobbly. Pictures here: https://imgur.com/a/azWHVuB Before I open this up, does anyone have any suggestions on where to start? I didn't see a NeXT section on Bitsavers. I am aware of the dangers of CRTs and will be sure to discharge the anode; I've worked on a few MDA monitors before. Thanks! Kyle P.S. From the hard disk error message, would you agree it's failing? Would this indicate total failure is imminent?

Does anyone have the stand for an HP-Apollo 9000/400t series, or specs for it (particularly the screws used to attach it to the main unit)? I haven?t seen screw specifications in the online reference material I?ve found, so it?ll be hard to make my own stand. Also, does anyone have a part number or other specifications for the internal disk sleds the 9000/400t series use, so I can secure the disks to the unit?

RS/6000 values

by BHuntsman＠mail2.cu-portland.edu

Hi there! I don't usually see much discussion on old IBM boxes, but I was looking for a reasonably-powerful RS/6000 that can run AIX 4.1 and maybe 3.2.5, can accommodate some decent disks, and isn't 200lbs. The 7012-390 looks perfect, but I found this one on eBay: https://www.ebay.com/itm/IBM-7012-390-POWER2-512MB-Memory-1GB-SCSI-2-Disk-D… Are 7012-390's really worth $3,000? Anyone out there have one they'd like to unload for less than 3 grand? :P Thanks! -Ben

Datasheet for a NEC Chip in DEC Professional 350

by robert.jarratt＠ntlworld.com

I have posted previously about a DEC Pro 350 I am trying to get working again. At the moment it seems to be constantly resetting the CPU. I have traced one possible path for the cause of this back to a NEC chip for which I cannot find a datasheet. It is a 40-pin DIP it is marked "NEC Japan 8239K6 D7201C". All I have been able to find is more modern USB host controllers. Can anyone tell me what it is? It is marked E32 (on the left about half way up) in this picture: https://rjarratt.files.wordpress.com/2018/10/system-board-labelled.jpg Thanks Rob

Rugged Nova

by technoid6502＠gmail.com

I got into the Data General scene in the late 1990's, when I received an Eclipse as a gift from a client who no longer needed it. In my search for docs, software, and other information I met some interesting people. One was in the Navy in the 1980's in data processing. He recounted to me: I was visiting a hangar where machines were being warehoused and tested prior to acceptance. I saw a lot of odd tests conducted, shocks, water, fire, smoke, the works, or so I thought. Once when there I saw a Hawk (That was a Data General milspec 'Eagle' - Eclipse 32 bit machine) suspended by chains from the overhead of the hangar. I was mesmerized as two weights were released from two chains on opposite sides of the machine as it was running. The two weights slammed into the sides of the machine at approximately the same time and the results were pretty spectacular. It sounded like someone blew up the Liberty bell, or crashed a VW into a lightpole. The machine continued to function! Most of the things that went on around there were classified to some degree or other and one got used to not asking questions, but as I looked over in bewilderment to my buddy in the group of tester, he said to me darkly "Depth Charges".

ROLM 1601 (RuggedNova) 1970 Brochure

by erik＠baigar.de

Hi Bill, thanks again for your considerations! --- Bill Degnan <billdegnan at gmail.com> wrote: > BTW - there is no evidence that the 1601 was not produced > at all, is there??? No, there is no evidence. But they founded ROLM in 1969 and they had no experience on designing a MIL-SPEC computer (until than only highly specialized MIL-SPEC computers had been designed taking years each) and only limited experience on computers at all. So I can hardly imagine, that they founded ROLM, agreed with DG on the architecture, developed the design, implemented the shock and heat management, tested against the MIL-SPECs set up production within only 2 years. Here is a nice video of a discussion with the founders recorded by the CHM: https://www.youtube.com/watch?v=VyTuxVQgw6c > The brochure came from a local office near where I used to live in > New Jersey USA.?? It could be that very few were made Yes, maybe some where made for trade shows and to try out how to build a MIL-SPEC computer. But regarding commercial sales I am still sceptic (no proof as you say)... Thanks, Erik.

How to work out unknown PSU replacement

by binarydinosaurs＠gmail.com

Hi folks, This week I managed to get my paws on a machine that I only ever saw in ?coming up!? type magazine articles in the mid-80s. It?s made by a UK manufacturer of Viewdata set top boxes and home micro modems called Tandata who were a split from Tangerine, the company that gave us the Microtan 65 and eventually the Oric 1 and Oric Atmos. Documentation on the Tandata PA is zero, if you search for it you get my Binary Dinosaurs page and nothing else so tonight I set about trying to work out the power inputs from its 4 pin socket. Going clockwise pin 1 is definitely GND/0V and pin 2 is not connected. Pin 3 goes to the input of a 79L05 -5V regulator which via a capacitor seems to be used as the GND pins for 3 CMOS 74 series chips. Pin 4 goes to a 7805 5V regulator. I?ve never seen a -5V reg be used in a GND circuit so before I continue searching am I barking up the wrong tree? The trace literally goes from socket to 79L05 pin 2, output goes to a capacitor then to the GND pins on a CD74HC74E, CD74HC86E and CD74HC4066E. There?s a VARTA battery nearby too. Board pic is here: http://binarydinosaurs.co.uk/tandatapa-13.jpg <http://binarydinosaurs.co.uk/tandatapa-13.jpg> Any insight much appreciated! -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? t: @binarydinosaurs f: facebook.com/binarydinosaurs w: www.binarydinosaurs.co.uk

Modcomp VME bus 68000 computer

by lyokoboy0＠gmail.com

Hello, been a while since ive written to the list. I met someone the other day that used to work for modcomp. He gave me a tour, he still has working modcomp computers in his home. He was clearing out a bunch of stuff, he gave me a bunch of terminals and dos era computers. Among the computers is a modcomp branded motorolla 68k based machine. I can not find any information on the system. From what i understand, the system was to be tied in to the modcomp minicomputer bus and used as a modern alternative for large antiquated disks and tapes. There is a large pair of interface connectors on the back, never seen anything like them before. I do not have a modomp computer yet, but this 68k machine looks quite interesting. It is essentially a vme bus backpane in a desktop computer case. A hard disk and tape drive are installed. Looks to have floating point and network card as well. I managed to make the proper serial cable, and was able to get to a debugger and monitor at power on. I was under the understanding that this machine could run a port of unix to 68k, called unix/68. I am uncertain of any details on the machine, i was hoping someone here could me in the right direction of getting the machine to boot. The drive still spins up, it may even have an install of unix on it, i might have to type in some kind of boot parameter or jump to some address from the monitor to kick off the boot process. Any advice on how to proceed is appreciated. Within the following month i am supposed to get a mountain of modcomp documentation, ill have to check back here and see if its duplicate or original information and scan it all. He was also going to give me a copy of a modcomp emulator he wrote, I have found no such thing elsewhere on line, so perhaps it would be of use to someone else here too once i get it. --Devin D.

A very sad PDP-8/S

In my opinion the ONLY way to preserve tech relics, is for individual(s) who understand the gear, to take personal responsibility for it.

All the way through that I was waiting for a mention of Fairlight Instruments (Synthesizer company in Sydney.) But none. Oh well.

Since I married in June 1987, I think the year listed on the video is wrong. Oh, and then the camera pans to a proto-board circuit I was working on. It's a bit of a tangle. I think that was part of a video timebase corrector system I was working on. My proto board, I still have it. >If there are any special 8/S lightbulb housings that were plastic, I'm happy to CAD them up and 3D print for your (er, museum's) machine at no cost, if I had some measurements or good photos. >I'm only 'up the road' in Brisbane. Thanks for the offer, but it won't be necessary. I'm spending today cleaning the machine and working out exactly how to make the 'clear protective base.' Bought most of the materials today. The front panel is in pieces atm. And clean now. Incidentally, several people called the material used for the lamps shroud plate 'MDF.' It's not, it's that high density cloth+bakelite (or something) material used for electrical switchboard panels. Very tough stuff.

Updates at retroarchive.org...

by geneb＠deltasoft.com

First up is the addition of Crescent Software's entire product line. The company produced a number of good library suites in the late 80s and early 90's. Note these are all DOS products - the Windows product line was sold in the early 90's. http://annex.retroarchive.org/crescent/index.html When the documentation arrives, I'll be paying the IA to get it all scanned. It's a lot cheaper than me buying a Scribe scanner or building a DIY version. :) Next up is a HUGE CD-ROM and FTP site archive I've been working on. http://www.retroarchive.org/cdrom/index.html What I've done here is pull CD-ROMs from the Internet Archive and make them easily browseable. I've also extracted the contents of each of the zip, etc. files and created index files for those as well. The goal was to make the material more easily accessible for both us meat bags and search spider bots. This is going to be a long term project that will end when I've either exhausted the available CD-ROMs on the IA, or I die, whichever comes first. ;) There's a number of holes in the sets that are on the IA - if you've got a disc that would fill a hole, please consider making an ISO of the disc and upload that along with a photo of the disc to the IA and then let me know so I can get it processed. I'm also looking to acquire a manual set for QuickBASIC 4.5 and the Microsoft Professional Development System 7.1. If you have either one, please contact me!

After I have docs on where all the flip chips should be, and I figure out a non-marking way to record which ones were in which slots, as I remove them to clean each one and the backplane. With precious museum pieces like this, you DON'T write numbers on them in marker pen. Just doing a quick eval now, since I'm already ridiculously stack-pushed with multiple other projects. Highest priority: Make a mechanical guard for the wired backplane pins. As it is now, just putting the machine down on a desk wrong could do major damage. Have to do this before I even pack it away in the box again. It's just been *really* lucky so far, with only minor pin bending despite inadequate packing. Guy

i860: Re: modern stuff

>the i860 found at least a little niche on graphics boards, so somehow >not a complete failure ;-) I'd be mildly surprised if Intel ever made enough from selling i860s as GPUs to cover the cost of developing and marketing them.

PDP8/a Initial Power Up (Columbia Valley Maker Space)

Hi, Most of the documentation is found here: http://www.bitsavers.org/pdf/dec/pdp8/pdp8a/ For some basic testing look here: http://www.bitsavers.org/pdf/dec/pdp8/pdp8a/EK-8A001-OP-002_PDP-8A_Operator… in chapter 5.1 (pdf page number 48). To do basic memory read and write: Press MD and DISP (memory data register will be displayed on the four digits) Then press 0200 and LA (load address) Press 5050 and D-THIS (deposit to memory on this adress, no increment). Press E-THIS (examine on this memory address, no increment) and you should get the same result back.

PDP8/a Initial Power Up

by info＠cvmakerspace.ca

Hello everyone - my first post, so be easy on me! I have just acquired a PDP8/a and a Remex punch tape reader. The unit starts up and displays some data on the displays, and that is about all I can tell you. I am going to do some googling about this, but I am looking for basic initial tests .... something I can enter via the keypad. I learnt some basic programming in 1978 on a PDP8, but that was the last time I touched one, so if you are going to suggest some tests, I need complete instructions. I don't know how to modify a memory location, let alone enter and check a program. I will pick all this back up very quickly and I do use computers in my work a lot - I am also an electronic hobby guy and have been for years. My point is I am OK with component level measurements, I have a scope and probes, etc. So there you go - hope to hear back form you guys.

Looking for HP Laserjet IIp+ power supply

by charlesmorris800＠centurytel.net

Actually I just fixed it ;) <Emily Litella> Never Mind. I took the supply all the way apart and found one secondary filter cap that had leaked electrolyte. Cleaned and fixed that, but still no luck. 155 volts on the main filter cap. Then I noticed that occasionally it would try to start for a blink but then the voltages would just drop to zero. So I started looking around the section that had to be for bootstrap power to the switching regulator, a common TL494 chip with datasheets online. Sure enough, a small electrolytic on the primary side had blown its bottom out. The diodes around it were still good. Changed that cap and a couple more suspicious looking small ones and the voltages came right up (including the 24V once I pushed the cover-open microswitch). Put it back in the printer, screwed it all together (a very modular design for easier field servicing) and fired it up. Test page printed perfectly. Saved some $ on a new laser printer. For now :) I like these old cinder-block-sized (and weight) printers too. They last ALMOST forever... Charles

Looking for HP Laserjet IIp+ power supply

by charlesmorris800＠centurytel.net

The main power supply for my ancient Laserjet IIp+ printer has given up. Fuse is not blown. Power switch has continuity... don't feel like trying to debug and repair the "brick". There are two Sony labels: One says Model RG1-1782 (I think that's the HP part number) and the other Model CD-91A, 100-115V. Does anyone have a working one in their junkbox? This is the LAST time I repair it before it goes to the recycler! I think I've changed every module except this one. It has become my grandfather's axe: new head and new handle, but it's still my grandfather's axe :) thanks Charles

If any of you are archiving old data for the public, like CD-ROMs or whatever, and you are low on disk space.... A friend gives me surplus data center hardware often, and I have some SATA disks.

70's computers

by jnc＠mercury.lcs.mit.edu

> From: Paul Koning > A lot more comes from the CPU architecture. The instruction set, of > course (arguably the first RISC). An observation about RISC: I've opined before that the CISC->RISC transition was driven, in part, by the changing balance of CPU speed versus memory speed: with slow memory and fast CPUs, it makes sense to get as much execution bang out of every fetch buck (so complex instructions); but when memory bandwidth goes up, one needs a fast CPU to use it all (so simple instructions). It occurs to be that the same balance probably applies to memory _size_. When memories are small, one wants dense code (which probably means CISC); only with larger memories does RISC, with its less-dense code, make sense. Noel

All these years later, I'm still trying to wrap my head around what the purpose of that in an OS/desktop environment/file-manager context is. I guess that, say, you could have new file types implement their own methods for things like printing, so the OS doesn't have to know the details of the document structure or require a particular application installed to be able to print it, but this seems like an awfully limited use case to me - sure, it would be nice to have things like audio and video codecs be universal and pluggable or things like that, but I have a hard time seeing how it's all that revolutionary, and I can easily see it being just as limiting as other non-OOP format standards (after all, it's not going to magically add functionality that the file format itself doesn't support, is it? And doesn't it ultimately just come down to diking out a chunk of the application code for the OS to use? What if two different programs both offer their own handlers for the same file type?)

Astounding Asking Price

by robert.jarratt＠ntlworld.com

My jaw dropped when I saw this: https://www.ebay.co.uk/itm/223201002247?ul_noapp=true It looks nice externally, and it has the pedestal, which is nice, but the seller has not even give the spec or posted pics of the innards and it is "untested". At that price I would expect a bit more information.. As it happens, I am trying to fix my 350 at the moment. Regards Rob

> From: Chuck Guzis > Danny Hillis' CM-1 also used lots of 1-bit processors. Does anyone know why they didn't catch on?

The boot ROMs for uPDP-11 contain loaders for XH (ethernet) was there any kind of standard for the server? It tries to load from a MOP DL server and I have modified mopd from NetBSD to respond and load 2.11bsd a.out. So I have a solution, but was curious if there was some DEC standard.

The DosFish (object oriented GUIS)

by technoid6502＠gmail.com

This was circulating in 1995/6. IBM had been shipping the very good OS/2 for some years and Microsoft was trying to catch up. Someone did a very nice parody. Jeff *****The Legend of the Pea Sea***** Long ago, in the days when all disks flopped in the breeze and the writing of words was on a star, the Blue Giant dug for the people the Pea Sea. But he needed a creature who could sail the waters, and would need for support but few rams. So the Gateskeeper, who was said to be both micro and soft, fashioned a Dosfish, who was small and spry, and could swim the narrow sixteen-bit channel. But the Dosfish was not bright, and could be taught few tricks. His alphabet had no A's, B's, or Q's, but a mere 640 K's, and the size of his file cabinet was limited by his own fat. At first the people loved the Dosfish, for he was the only one who could swim the Pea Sea. But the people soon grew tired of commanding his line, and complained that he could neither be dragged nor dropped. "Forsooth," they cried, "the Dosfish can only do one job at a time, and of names he knows only eight and three." And many of them left the Pea Sea for good, and went off in search of the Magic Apple. Although many went, far more stayed, because admittance to the Pea Sea was cheap. So the Gateskeeper studied the Magic Apple, and rested awhile in the Parc of the XerOx, and he made a Window that could ride on the Dosfish and do its thinking for it. But the Window was slow, and it would break when the Dosfish got confused. So most people contented themselves with the Dosfish. Now it came to pass that the Blue Giant came upon the Gateskeeper, and spoke thus: "Come, let us make of ourselves something greater than the Dosfish." The Blue Giant seemed like a humbug, so they called the new creature Oz II. Now Oz II was smarter than the Dosfish, as most things are. It could drag and drop, and could keep files without becoming fat. But the people cared for it not. So the Blue Giant and the Gateskeeper promised another Oz II, to be called Oz II Too, that could swim fast in the new, 32-bit wide Pea Sea. Then lo, a strange miracle occurred. Although the Window that rode on the Dosfish was slow, it was pretty, and the third Window was prettiest of all. And the people began to like the third Window, and to use it. So the Gateskeeper turned to the Blue Giant and said, "Fie on thee, for I need thee not. Keep thy Oz II Too, and I shall make of my Window an Entity that will not need the Dosfish, and will swim in the 32-bit Pea Sea." Years passed, and the workshops of the Gateskeeper and the Blue Giant were many times overrun by insects. And the people went on using their Dosfish with a Window; even though the Dosfish would from time to time become confused and die, it could always be revived with three fingers. Then there came a day when the Blue Giant let forth his Oz II Too onto the world. The Oz II Too was indeed mighty, and awesome, and required a great ram, and the world was changed not a whit. For the people said, "It is indeed great, but we see little application for it." And they were doubtful, because the Blue Giant had met with the Magic Apple, and together they were fashioning a Taligent, and the Taligent was made of objects, and was most pink. Now the Gateskeeper had grown ambitious, and as he had been ambitious before he grew, he was now more ambitious still. So he protected his Window Entity with great security, and made its net work both in serving and with peers. And the Entity would swim, not only in the Pea Sea, but in the Oceans of Great Risk. "Yea," the Gateskeeper declared, "though my entity will require a greater ram than Oz II Too, it will be more powerful than a world of Eunuchs." And so the Gateskeeper prepared to unleash his Entity to the world, in all but two cities. For he promised that a greater Window, a greater Entity, and even a greater Dosfish would appear one day in Chicago and Cairo, and it too would be built of objects. Now the Eunuchs who lived in the Oceans of Great Risk, and who scorned the Pea Sea, began to look upon their world with fear. For the Pea Sea had grown and great ships were sailing in it, the Entity was about to invade their Oceans, and it was rumored that files would be named in letters greater than eight. And the Eunuchs looked upon the Pea Sea, and many of them thought to immigrate. Within the Oceans of Great Risk were many Sun Worshippers, and they had wanted to excel, and make their words perfect, and do their jobs as easy as one-two-three. And what's more, many of them no longer wanted to pay for the Risk. So the Sun Lord went to the Pea Sea, and got himself eighty-sixed. And taking the next step was He of the NextStep, who had given up building his boxes of black. And he proclaimed loudly that he could help anyone make wondrous soft wares, then admitted meekly that only those who know him could use those wares, and he was made of objects, and required the biggest ram of all. And the people looked out upon the Pea Sea, and they were sore amazed. And sore confused. And sore sore. And that is why, to this day, Ozes, Entities, and Eunuchs battle on the shores of the Pea Sea, but the people still travel on the simple Dosfish.

DEC 8640 Pinout

by robert.jarratt＠ntlworld.com

I am trying to trace the reason why the CPU on my Pro 350 is apparently being constantly reset. I have reached a DEC 8640 chip. Does anyone have a pinout for it, perhaps even a datasheet, so I can understand what it is supposed to do and whether the pin is an input or an output? Thanks Rob

"Object Oriented GUI"

by technoid6502＠gmail.com

I used OS/2 from 1993 to 2003 almost exclusively. It has the most beautiful GUI on the planet, is object-oriented to a fault, and is the target of all the claims Microsoft was making with regard to the Object-orientedness of their new windows 95. Wikipedia https://en.wikipedia.org/wiki/Workplace_Shell mentions some important attributes of a truely object-oriented gui. Someone mentioned inheritance and polymorphism. These are two products of true object oriented gui design. Applications inherit the ability to manipulate and use whatever objects exist in the system. A word processor is not limited to just text files, for example, or to only the files the programmer originally set out for it. The system allows the applications to grow in functionality as new object types are developed/assembled by other applications or the user. I gather, though I have not had the opportunity to play with it, that the Next Gui was also extreme in its object-orientedness, though I can't see that from MACOS (its inheritor), I understood that to be the case? At any rate, if you want a fantastic example of a object-oriented graphical user interface, check out the Workplace Shell. Jeff

Cossor/Raytheon DIDS-400

by camiel.vanderhoeven＠vmssoftware.com

I just rescued a Cossor DIDS-400 terminal from ending up at the garbage dump. Cossor was a UK company, that ended up as a Raytheon subsidiary, and the Cossor DIDS-400 was marketed as the Raytheon DIDS-400 in the US. My terminal is model no 402-2/C15, part no D/GA 800260, serial no 023, option table code 321121. Date codes on the IC?s are in 1968. Internally, there?s some interesting technology; ITT MIC9xx DTL IC?s, a piano wire delay line for character storage, and a Raytheon Symbolray monoscope tube as the character generator. I?d love to get this terminal working again, and to that end I?m looking for any kind of service documentation (any other documentation would be welcome too, as I have nothing). The power supply in this terminal consists of two parts, manufactured by Best Products Ltd, of Felixstowe, Suffolk, models 508-L (low voltage supply), and 508-H (high-voltage supply). Any documentation on these would be most welcome, too. Kind regards, Camiel Vanderhoeven

FP11-A Technical Manual

by jnc＠mercury.lcs.mit.edu

So, I bought a copy of the FP11-A Technical Manual (EK-FP11A-TM), but when it got here, it was the 'Preliminary' version (-PRE), with type-written text, some of the figures are hand-drawn, etc. This manual does not seem to be generally available online, although at one point a copy was available for download briefly; although it's not the greatest scan job, I have put it up here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/EK-FP11A-TM-002.pdf So, is it worth my scanning the -PRE version, or should I just punt, and we'll go with that scan of the -002?

PinOut of DEC F11 Chips in a Professional 350

E151 is the main CPU chip: http://gunkies.org/wiki/F-11_chip_set E152 is the KEF11-A floating point chip, and E150 is the KTF11-A memory management chip. Pin 1 of E150 is definitely in the lower left corner (in the photo); there's an indent on the left-hand side of the chip, for the usual DIP orientation. I'm pretty sure the other two have the same orientation. Noel

PinOut of DEC F11 Chips in a Professional 350

by robert.jarratt＠ntlworld.com

As I mentioned in an earlier thread, I am trying to repair a DEC Professional 350 system board. I think I know the pinout of the F11 chips >from a KDF11-A printset, can anyone confirm that pin 23 of the DIL package is the RESET signal? If that is correct then it is oscillating and resetting the machine constantly. I am trying to trace the source, but it seems to go through quite a few chips and I haven't yet traced its source. The chips where I believe the RESET is oscillating on pin 23 have been labelled E151 and E152 in the following photo: https://rjarratt.files.wordpress.com/2018/10/system-board-labelled.jpg But I am not really sure if I have identified them and the pin correctly.

As a rough measure of how much more complex, the -8/E and -11/20 are roughly contemporaneous, and built out of the same technology (SSI TTL on larger boards): the -8/E CPU is 5 quad boards, and the -11/20 CPU is 9 quad board (equivalents - some are duals, etc).

The whole desktop metaphor UI existed long before Windows 95 in non-Unix implementations by Xerox PARC (Palo Alto Research Center) with the pioneering Xerox Alto, introduced in 1973, which implemented Alan Kay's concepts for the desktop metaphor that were postulated in 1970 using Smalltalk as the core operating system. Windows 95, and the earlier versions of Microsoft's desktop metaphor UI's, were patterned after these implementations. Microsoft simply took concepts that already existed in the world of UI design, and made their own implementation based on those concepts. -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

does a reverse-engineering EDA tool exist?

by aek＠bitsavers.org

To draw out the schematics for the Displaywriter I have a bunch of boards to trace out, and I don't want to do the usual "scribble on yellow pad" to do it. Has someone written a graphical tool for doing this? What I would like to find is a tool that puts up a bunch of footprints with internal IC functions shown, then a way to rapidly enter the buzzed out interconnections, generating a netlist. This is exactly backwards workflow from normal schematic entry and pcb layout. I suspect I'm just going to have to bite the bullet and write it..

High res e-readers

by shadoooo＠gmail.com

Kobo have a quite plain Linux, run on iMX processors, and are very easy to modify/script, and last but not least, to unbrick in case of severe problems. In many models, the internal memory is an SD card, so it can be expanded easily. Then you have also external SD. On the software side, try koreader. It's an open source reader, developed for eink devices. It works very well with PDFs, and can do intelligent text reflow, even on raw scans of books, via a sort of OCR. The nice thing is that it doesn't convert bitmap to text, but seems to split long lines of text in shorter sections, then rearranges the pieces on the screen, following font size options. It can be instructed to work as expected on multi column pages. Very nice! Andrea

Advice needed: Entry point into things PDP-8

by ce.murillosanchez＠gmail.com

Greetings all... I have been pondering something and would love to receive feedback from you.? The thing is, I would like to have something pdp8-ish that would allow me to play a little bit with the programming languages that were available for these machines, FORTRAN 4K and FORTRAN IV in particular.? Now,? I would love to be able to time some FORTRAN jobs just to get an idea about what it was like back then.? I am aware of PiDP-8, simh, as well as SBC6120, SBC6120RBC. I happen to have three VT78 cpu boards (sans the RAM board) and two vt278 cpu boards. All were in rather sorry condition; I picked them up from a junk pile that was stacked several feet high and in which the contents were mostly random. Thus, the VT78 boards' components were scratched and in fact two of them are missing the control panel ROM chip. Otherwise they are complete, but I am missing the RAM boards.? The VT278 boards were further abused by someone who yanked out the oscillators and a few TTL chips, damaging several traces, which I have now repaired.? Alas, only one of them has the HM6120 cpu chip, and I do not know if it is good or not. Both are missing the SMC5037 CRT generator chip.? Other than that, they are complete. So, now that we all know what I have, let me say out loud what I've been thinking: If I try to build actual hardware: I've read that the VT278 has serious software compatibility issues with older software due to the use of the HM6121 I/O chip.? So even if I get an adequate keyboard, buy the CRT chip and manage to use it to drive a monitor, I would need an original floppy drive system and media, because I do not have the DP278 serial comms board that would allow me to send the VT278 a program to run; For the VT78, I would need to hack a memory board, and, since it can be coaxed to accept a program to run if it is fooled into thinking that it is loading a program from an MR78/paper tape, perhaps I could make it boot something.? I would need to wire-up and arduino or something like it to translate the keyboard and display terminal chatter in the serial console into something usable.? But, that's three hardware projects (memory board, MR78-like contraption, microcontrolled serial console translator)... The last hardware option is to go and make an SBC6120RBC;? I would need to buy programmers for the GAL/PAL devices, and I've heard that not all programmers can deal with the kind of chips used in it.? And, if it turns out that the HM6120 chip that I have is bad, I would have to hunt down one of those rare beasts.. It would be awesome, though, to have an SBC6120RBC up and running, and be able to time actual hardware running FORTRAN. And then comes the emulation option, with the PiDP-8.? I have to say that the emulation of the blinkenlights is very, very attractive to me, and this option is a no-brainer hardware-wise. So...? am I missing something in my estimation of the effort involved in these options? What would _you_ do? Carlos.

Selling keyboards without the terminal

by billdegnan＠gmail.com

Here is a great example of why the keyboards and terminals are getting separated https://www.ebay.com/itm/IBM-3101-beam-spring-keyboard-purchased-new-in-198… Note the price $2000 so far. How could one blame the seller. I wonder if this is the terminal I sold to a buyer in California years ago when I sold my Series/1 computer. All he wanted was the terminal, I donated the rest to what was the MARCH museum. At the time I remember having a few words with the buyer who would not also take the Series/1 system (2 racks) or the manuals. There is a naked terminal up for grabs if you're out his way. Bill
