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).

Replacing "Unix" with "Linux" would make the statement more correct. X-Windows-based desktop metaphor UI's existed within the Unix world long before Win95 came on the scene. 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

Have to concur with this. Even the "minimalist" (i.e. non-GNOME/KDE) *nix "desktop environment" projects these days are getting so bloated that I've given up bothering with them and set up an X environment one component at a time. Currently running Window Maker with SpaceFM and ROXTerm; getting it all properly set up and tweaked to my liking took some doing, but the payoff was well worth it. Now if I could only excise the GTK3 blight entirely, I'd really be set.

There was a recent discussion about code density (I forget whether here, or on TUHS), and someone mentioned this paper: http://web.eece.maine.edu/~vweaver/papers/iccd09/iccd09_density.pdf which shows that for a combo of benchmarks, the PDP-11 had the densest code out of all the ones they looked at. (They didn't look at the PDP-8, but I suspect that since it's a single-address design, it's almost ceertainly not as dense.) The PDP-11 dates back to the days of core (it went through several generations before DRAM arrived - e.g. the -11/70 originally shipped with core), and given core prices, minimizing code size was pretty important - hence the results above. So if you want to get the most bang out of 16K buck... Not the simplest machine to implement, mind - the -8 is a lot simpler. Which axis is the most important to you? Noel

There's also the Afterstep/Window Maker crowd, open-source reimplementations of the NEXTSTEP desktop environment, which predates even Windows 3.x. Win95 was certainly very influential in the design and refinement of many other desktop environments going forward, but it's not the be-all and end-all of anything. >> Liam Proven wrote: > > How many graphical Unix desktops are sold or distributed in the world > today that are not Linux?

But this is kind of a questionable standard to begin with, because the whole point in the Freenix world is choice. No distributions offer those as default options during the install process, but all of them (aside from CDE, which only just went open-source a couple years ago and is still in the process of being cleaned up and forward-ported to modern *nixen) are available in the repositories for most major distributions, and all of them are still actively updated. > BeOS used the Windows model. Kinda-sorta-not-really. BeOS (like just about everything post-1995) takes cues from Win95, but its roots are in classic Mac OS and it definitely hews closer to that in most respects, despite the absence of a global menu bar. > Outside of Apple, I think it is fair to say that no new OS or desktop > environment since 1995 has used anything other than the Win95 model.

This "aside from the things that don't match up with my argument, my argument is flawless!" line of reasoning is novel.

I mostly use rio (based on the same named windowing system on Plan 9) for my window manager so at least I get to avoid the dancing frogs.

It was only a processor card. > Eric, I'm going to stand by my assertion that the Softcard was a single-board computer on the technicality that it did have its own RAM - you apparently forget that registers are a form of RAM - HA! They're memory, they're addressed over a bus (that just happens to be within the microprocessor), and you can directly access any register at any time (random access). As for I/O, that's what the Apple ][ bus was for, right? As Opus from Bloom County, among other comic characters, was known to utter, "PBBBBBBTTTTTT!!! ? Microsoft did offer a RAM expansion board specifically to allow the Softcard to access 64K of RAM dedicated to CP/M, and the Premium Softcard //e provided on-board RAM to CP/M for the Apple //e, as you noted. All models of the Softcard could output 80 x 24 text, not only through third-party cards, but Apple's own 64K RAM and 80 x 24 video combo card, which was often offered in packages, especially through dealers that supported business customers (that's how my system came delivered). The "etc." I mentioned was the functionality provided through the glueware logic on the Softcard that enabled RAM and 80 x 24 text output, as well as other I/O over the Apple ][ slots bus. When I was in the Navy, our ship called at HMS Tamar in Hong Kong, and I followed verbal directions (26 stops on the then-new subway under the harbor into the New Territories) to the basement level of a shopping center. There, I found clones of everything from Apple ][s and //es to every expansion board and peripheral available in the early 1980s, including both the original Softcard and the Premium Softcard //e. Everything came complete with the floppy disks and every page of the documentation, not just photocopied, but professionally typeset and offset-printed. In your missing-the-forest-for-the-trees response, you completely missed the point of my post - that the Softcard was an extremely important early product for Microsoft, the critical connection between the Softcard and the QDOS prototype for x86 MS/PC-DOS, through Seattle Computer Products, and that the number of CP/M licenses was much larger on Apple computers than S-100 systems. For those that cited the Amstrad systems, I was referring to the S-100 and Softcard timeframe. CP/M was only provided with the Amstrad CPC664 and 6128 floppy-disk based models, and the DDI-1 disk expansion unit for the 464 (only CP/M 2.2 with the 664, and 2.2 and 3.1 with the 6128). The Amstrads came along four years after the Softcard was introduced, and three years after the release of the IBM PC. By that time, Digital Research's influence had faded into insignificance, despite the full release of CP/M-86 within six months of the IBM PC's debut (albeit at six times the price of MS/PC-DOS). I do know that CP/M was used in European banking systems well into the late 1990s, mostly because it wasn't broken and didn't need to be "fixed". It probably would have remained in use well past 1999 if it weren't for Y2K's impetus for massive upgrades to current technology for 2000 and beyond.

PDP8A Power Distribution Board

by marco＠familie-rauhut.eu

Hello alltogether, i am restoring a PDP8A at the moment. The machine got a problem in the Powersupply. I think one of the emergency ciruits trigger a shutdown of PSU. In tracing this isue i hab two questions. My 8A`s manufacturing year is 1977. It`s model is 8A620. On Bitsavers i found a matching shematic for the BA8C Power distribution Board from 1976 (File: EK-8A002-MM-002_PDP-8A_Miniprocessor_Users_Manual_Dec76.pdf page 597). The Board Number is 5412000-0-1. My first question is if somone has the Board Layout with it's component locations? My second question is about the DEC4011 Chips. As i inspected the Board i found the DEC4011 Chips. First i think they are the standard CMOS 4011 quad two-input NAND`s. In the shematic it look more like a four Transistor array. Did anyone know somthing aput these Chips? Are there any equivalent parts? Have anyone a Datasheet of it? Marco

Selling keyboards without the terminal

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > The quality of modern keycaps is poor. > These guys are after mechanical boards with double-shot keytops. There's something I'm still not quite grasping. I can see two reasons for people liking the old keyboards: - i) Higher quality construction - ii) Connection, through a historial artifact, to an earlier age Am I missing any? I can definitely see the first (I myself find many modern keyboards to be complete crap), but if that's _all_ it is, I'd think there'd be a market for modern production of quality keyboards - not a large market, true, but I'd think it would be large enough to be worth servicing? (Unless the cost to produce such would be so high that there wouldn't be any buyers - but that seems at odd with some of the prices being mentioned.) So maybe people _only_ want keyboards that have both i) and ii)? Noel

Selling keyboards without the terminal

> From: Doc Shipley > You guys want people to stop scavenging those irreplaceable treasures? > Ante up, pure and simple. That works for keeping stuff out of the hands of scrappers (who are, after all, business-people) - but not for fetishists who will pay totally mind-blowing sums for them. Sorry, I'm not paying $5K for _any_ keyboard. You can buy (for example) a complete PDP-11/70 for that much money. > In the end, that system is worth twice as much as desoldered parts as > the best offer I got. But will _all_ of the constituent parts sell, or just some of them - the rest being destined to sit on a shelf, un-sold, until they are pitched? There's a similar debate in other areas of collection - e.g. antique Japanese woodblock-printed books. One can usually make more money by taking them apart, and selling them a page at a time, as opposed to selling them as complete books. (At least all the pages do tend to sell.) Some people consider this vandalism - destroying a 200-year old artifact to maximize $$. I can't say they're wrong... Noel

FYI: From: Lars Brinkhoff Date: Fri, 19 Oct 2018 11:08:29 +0000 I have Alan Snyder's C compiler running in case anyone would like to play with it. It's from around 1975, so the syntax is yummily archaic. The primary host is a PDP-10 running ITS, but there may also be machine descriptions for Honeywell 6000 series and PDP-11. At some point it seems like this compiler was tangled with Stephen Johnson's PCC.

Working with Old Tapes

by technoid6502＠gmail.com

Probably preaching to the choir, but if you are going to be mounting an old tape, there are some issues to be aware of. Tape is really stable over time and your data is likely still there. As tapes age, the surface of the gluey oxide coating degrades. The symptoms will be very discernable with a nine-track drive as you can see the head/tape interface easily. The surface of the tape in contact with the drive's head will ablate, leaving gunk on the head. The tape will make a squeaking noise while running and may eventually stop moving due to sticktion at the head. Cleaning the head from time to time may get you through a read of a tape for backup purposes, but there is a machine called a 'tape cleaner' which is a drive which leads the tape through a path seeded with knife-edges. As the tape travels through the machine, the knife edges scrape a layer of oxide coating from the tape and smooths and polishes the surface exposed. This will restore a tape to full usability and should not affect data stored on the tape. Pinch rollers can also collect oxide and need cleaning. Pinch rollers on old drives may be so degraded as to make the drive unusable. I had a Data General cart drive using Qic 300? tapes. The drive roller was wrecked. I found in my junkpile a roller from an Epson Actionprinter 3250, removed it from the printer's output roller and after cleaning the drive axle in the qic drive, used some windex to lubricate a ballpoint pen barrel, stretched the roller onto the pen body, held the body to the face of the drive axel and pushed the roller on. It worked beautifully from then on. Stone knives and bearskins. You can carefully make a set of knife edges on a board, thread the tape through the edges, and use the drive you have to move the tape through your homemade cleaner. Best, Jeff

So, I recently acquired a copy of the unavilable on-line -11/44 Tech Manual, EK-KD11Z-TM-001; alas, it's bound, and I don't wish to debind it to scan it. If anyone has one of those gizmos that can scan bound books, and wants to scan this, please let me know, and I can lend it to you. Noel

Ultrix Tape: Block Size?

by wkt＠tuhs.org

All, I received this request from Matthew who isn't subscribed to either the TUHS or cctalk lists. He knows how to read the lists archives. Many thanks for any help you can provide. Cheers, Warren ----- Forwarded message from Matthew Whitehead ----- Date: Mon, 15 Oct 2018 08:25:39 -0400 From: Matthew Whitehead Subject: Ultrix Tape Blocks Warren, I wonder if you can give me a referral. I want to install Ultrix-32 on my MicroVAX II using the ancient TK-50 tape drive. I know the tape files are on your archive, but I need to know the block size for each of the many files; it can vary a lot. Who might be able to help me with this?

RT-11 DY install

I'm entirely not sure why SIMH has to enforce this >> as its possible to work around .. Anyone know how to override and load >> in SIMH? > If it didn't it wouldn't be emulating real PDP-11 hardware. ... > RX02 systems and they do not work with more than 256K. Right, the hardware only has 18 bits of 'buffer address' (in both UNIBUS and QBUS versions). But one can still plug one into a QBUS system with more than 256KB, and use it - you just can't use memory above 256KB for transfers to/from the RX02, since it cannot physically create those addresses. If sounds from Jerry's description as if SIMH refuses to emulate an RX02 if the emulated system is configured with more than 256KB - which would be a bug, if so. Noel

Josh - You may want to contact Denis Kohlhagen, at Butler Winding. IF this is for the preservation of an HP terminal in the museum, they may wish to assist in rebuild/rewinding that flyback. There are US firms that can perform this work, and publicity of preserving history is desired by some corporate marketing dept.

Wanted: tech docs on original Iomega 8-inch full height 10MB Bernoulli drive (Alpha-10)

by spacewar＠gmail.com

Does anyone have the user, technical and/or service manual for the original 10MB Iomega Bernoulli drives? Bitsavers has the manuals for the later half-height 10.0/10.5 MB "Alpha-10H", but I'm looking for docs for the original model, which was full-height with a SASI (pre-SCSI) interface. I have the drives, about 20 cartridges that I want to image, and some additional scratch cartridges. I've never used Bernoulli drives before. These drives and cartridges were last used around 1986. I'll disconnect and test the power supply before powering up the actual drives, but is there anything else I should be concerned with? Does anyone have known-working 8-inch Bernoulli drives?

Maybe head cleaning is what is troubling the others - but I have no idea how I'd jam a cotton swab in there and find the heads to attempt a cleaning. I have a Bernoulli card in a PC that will lift the bits from DOS-formatted cartridges, and I hook the drive up to an old Mac with a SCSI card in it to image other arbitrary types (I've seen them used as audio recording devices as well as external storage for HP equipment). - David

Apple IIe addendum

by drlegendre＠gmail.com

Folks, Yay, I was wrong! The IC seems to be OK, the issue was a stuck-on kb switch. A quirk of the Apple design causes the last-pressed key to repeat continuously if any key is being held 'on'. That leaves me needing two kb switches and possibly one 'tilde' key. This is the beige IIe kb with small black print. Thanks for the space, Bill

TeleVideo Systems stuff

by pat＠vax11.net

After VCFMW this year, I've been looking at old projects I have and was wondering if anyone has any leads on TeleVideo systems. I'm looking for TS-800 terminals/systems, and interested in probably any 1980s Televideo terminals, depending on price, especially the 950, and 965s... and keyboards for them. I'd also like to find a TPC-II (the 8088-based portable computer). I used to have one growing up, and there's a bit of nostalgia there. It seems like there's more Televideo stuff lately than I remember being on eBay before, but it's all fairly expensive, especially the computers. I have picked up a few affordable things (970 & 965 terminals missing some keyboards and a TS-803 that I'm still waiting on). I have a couple of TS-801's, TS-806C and a TS-816 that are in various states of repair, that I've been poking at. I also have various Qbus era DEC stuff that I could probably trade for it. Any leads would be appreciated! Thanks, Pat

Altos 386/1000 boot/diags images?

by gordon+cctalk＠drogon.net

Long shot, but you never know... I recently obtained an Altos 386/1000 system (80386 + 4GB RAM in a tower case with tape drive and floppy) After a quick clean and check it powered up, gave a whinge about a flat battery (which I'm told is to be expected), and then booted SysV r3 Unix OK. After an hour or so poking about, I shut it down then powered it up again a short time later... Now, it starts up, does the power on checks (including the battery whinge), loads Unix, prints some information about memory and a 16 user license then stops. No more messages, no keyboard input, nothing. So I'm a bit stuck. I've found some manuals online but they're not really helping - I'll take it to bits later and see if I can read the internal SCSI drive on another system but I'm not convinced there is an issue with the drive though. So wondering if anyone knows of any installation (or diagnostic) images for these machines? It has a SCSI tape drive and I have some tapes for it, so with some SCSI shenanigans I'm fairly sure I can write a boot tape on a Linux system, or maybe even the floppy - but I need the images... Any clues? Thanks, Gordon

WTB: BPK-72 or Bubble Memory Dummy Module + Seed Module

by saburwulf＠gmail.com

Currently working on restoring some bubble memories and I'm looking for some modules originally included in Intel's BPK-72 development kit, specifically the Dummy Load module and the Seed module. http://archive.computerhistory.org/resources/still-image/Intel/intel.dummy_… These are used for testing a bubble memory system as well as repairing bubble modules which have had some sort of failure which requires manually re-seeding them. I have all the parts I need to work with the modules, I'm just missing these parts. The manual shows the schematics, component values, and layouts of both of these modules, so I can fabricate them myself if need be, but wanted to see if anyone had them handy first. Thank you again!

Anyone know where uPD2167 SRAMs appeared?

by ethan.dicks＠gmail.com

Hi, All, I asked a version of this question earlier this year. I have not been able to find any vintage machines that used these 16Kx1 55ns SRAMs. Anyone recognize them? Lots of them for sale on eBay. Probably few buyers. One would want to know which systems used them, thus my question. They probably would have been excellent in a DEC MOS memory board but I have no evidence they were used thusly. Contemporary DRAMs were cheap and 64Kx1 so that's what was in consumer gear. Anyone? Fast SRAM? Anywhere? There's little point in wiring 8 of them up into a byte vs using a 62256 except for speed. 55ns is faster than any 8MHz machine really needs (100ns-150ns was typical for those depending on bus architecture). I could see these being cache RAM for a minicomputer vs primary RAM. -ethan

WTB: BA11-K Rack Rails

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > I don't remember the D tilting. http://gunkies.org/wiki/File:BA11-DSide.jpg This is very similar to the slides on the BA11 (-11/20), which also had the rotation, so I suspect they were all this way (i.e. there no early versions without, etc). Having said that, if anyone has a -D with something else, please send me an image so I can document it. > From: systems_glitch > I'd prefer a set of original outer rails, but something newer or > something I have to modify a little would be fine. Probably the easiest option is to buy a set of those C-230-S's; the mounting holes on their inners match the locations of the swage nuts on the BA11-K sides, so it's straight simple bolt-in. You'll lose the rotations option, though. Noel

> From: Bill Degnan > What is the part number for the -D ? Do you have the inners? The only -D inners I know of are the kind shown here: http://gunkies.org/wiki/BA11-D_Mounting_Box and if you have those, you're in luck; the outers from a still-available Chassis Track unit are perfect replacements for the original outers. Kinda pricy, mind, but at least they're available. If you have a different inner, I'd love an image, so I can see what it is, and document it. If you have no inners, kinda ugly. You can buy that CT unit, but you'll have to drill matching holes in the inner - and you lose the rotational capability. Noel

> From: systems_glitch > I do have the inner rails/latch system for tilting the box, they are > plain aluminum. Like the lower picture: http://gunkies.org/wiki/BA11-K_mounting_box there? I'm guessing that's zinc-plated steel. Alas, I don't know who made those (may have been DEC themselves), or a source for them. _But_.... I have some Chassis Trak outers which are almost compatible. (I say 'outers', but actually many slide sets are 3-part; there's an outer which bolts to the rack, an inner which bolts to the mounting box. and then a third piece, a 'middle' I guess we can call them. Sometimes the middle and outer can be separated, with a safety latch you have to release - but I think I recall seeing one set where you can't extract the middle mrom the outer - at least not out the front.) Anyway, the silver inners do fit into the track in the middles of those CT units - all except the two wheels at the inside end of the inners! Too bad, because I have no use for these outers, and would be happy to hand them over to you. The other possibilithy is that I _might_ have a spare set of the silver outers. I have 2 sets of the outers (2 left, 2 right), 4 of the special pivot bolts - but only one set of inners - at least that I can quickly find. Let me have a look around, and see if I'm really missing the inners - if so. I might be up for trading you a set of outers for something I can use. Noel

The -K has the power supply on the end, the -D down one side. What slide hardware, if any, do you already have?

I used to have a SCSI interface version of that drive type, I made backups of my Mac Plus (I think it was) hard drive. Since I don't have it currently, I believe I gave it to a friend along with the rest of my Mac Plus peripherals. I don't recall the capacity of my specific drive, but it used a "data cassette", which had a notch in the tape case to prevent use of regular cassette tapes.

CPT boards

by jules.richardson99＠gmail.com

I borrowed a pile of scrap 1970s-era PCBs from my local recycler yesterday, just to make sure there was nothing important among them before they go off for processing. Among them are six boards branded as CPT, which I assume (as I'm in MN) is the CPT Corporation that was in Minneapolis. The double-sided boards are organized in five rows of five ICs, with 44-way edge connectors and IC date codes in the 1973-1977 range. I seem to have p/n's 910012, 910014, 910015, 910017, 910018 and 910022. In addition to this there's a smaller board which references "deck 1 heads" and "deck 2 heads", and appears to have a p/n of 910025. Does this ring any bells with anyone? The Wikipedia entry for CPT mentions the 'VM' machine in 1976 with dual tape units, so I wonder if they're from one of those... if so, I'm curious if there are any surviving intact examples out there (or other info, there doesn't appear to be any CPT stuff on bitsavers) cheers Jules

Ethernet names...

by mark.kahrs＠gmail.com

I was there and it was always called "The Ethernet". When the 10 Mb standard came into being, it was then referred to as "The Experimental Ethernet". If you want to be *really* pedantic, you could refer to it as the "2.94 MHz Ethernet" --- but that would be silly.

We recently got a Digico Micro 16V computer including a Pertec 3342 disk drive. It is a 16 bit minicomputer based on 74181 ALUs and a couple of 4k core memory modules. Since the condition of the system is not the best (dirt, dust, some bent wirewrap pins), I'm looking for the usual information :-)) - technical manual, schematics - software I'm thankful for any information.

Ethernet names...

It's quite possible that in Metcalfe's interview (which is what the WWSUL account seems to be pretty much wholly based on), N years after it all happened, his memory flaked and he got the sequence wrong. I've had the same thing happen to me, trying to recall the sequence/timing of early IP work at MIT. I was sure X happened before Y, and then Jerry Saltzer dug up an old progress report... There's a reason that the gold standard for historians is contemporary documentation. Along those lines, here: http://www.chiappa.net/~jnc/nontech/tmlotus.html is an amusing story of my encounters with this effect on some Lotus Indycar research I did. Noel

Does anybody know names / terms that correspond to the original 3 Mbps Ethernet? I.e. 10 Mbps Ethernet is also knows as Ethernet II (2) and D.I.X. (for Digital, Intel, and Xerox). Was the first 3 Mbps Ethernet simply called "Ethernet" with an implicit "I" (1)? Was there a name to differentiate it from D.I.X.? Grant. . . . unix || die

PDP-15 documentation

by mattislind＠gmail.com

I have now finally concluded the PDP-15 documentation scanning project. Many year ago my father saved a big lot of PDP-15 documentation that was thrown out from Philips in Stockholm. I have over the years scanned documents on request which has ended up at bitsavers. Some docuements were already present on bitsavers. Now I took a stab and finalised this project. All the remaining PDP-15 has now been scanned and I put them here: http://www.datormuseum.se/documentation-software/pdp-15-documentation Many documents already has made its way to bitsavers but many remains. There are DOS-15, XVM/DOS and various general documents such as operators guide, course handouts etc. The only remaining document to scan is the RSX PLUS III reference manual which will be tricky to scan without damage it. Happy reading!

Source code listings from REDAC PDP-based PCB layout system.

by mattislind＠gmail.com

I have a set of around 5 to 8 binders with printed source code listings >from a PDP-15 system. The listings appear to be from a REDAC SOFTWARE LIMITED PCB CAD system. The name of the software seems to be REDAL 3 MARK 7. There are dates on the listings in the range 74 and 75. https://i.imgur.com/m1ji9uR.jpg https://i.imgur.com/SzaiH78.jpg First of all does anyone has more info on the REDAL software from REDAC? Then secondly is there anyone interested in these binders with listings? I think the quality of printout is good enough to do OCR on. Note that there is no guarantee that these are the complete set of binders with listings. /Mattis

Rack-mount or tabletop version of DEC RX50 floppy drive?

by spacewar＠gmail.com

Did DEC offer a rack-mount or tabletop box version of the RX50 floppy drive, as they did with e.g. the TU58 and TK50 tape drives? I'm wondering how they expected the RX50 drive to be packaged when used with a Unibus PDP-11 via the RUX50 controller.

Ethernet names...

by w9gb＠icloud.com

Grant - Occasional vague references to ?I?, when Ethernet II was used (as I remember). I assumed the reference was for initial 3 Mbps work at PARC. Gateway Communications started in Irvine, CA (1981?) offering G/Net (~double the 3 Mbps), I remember installing their demonstration system (1982 or 1983?) By 1983, 3Com ThinNet (10-Base-2) released for IBM PCs. University of Iowa graduate college installed one of their first LANs with an Altos sever (8086, 10 MHz). greg == From: Grant Taylor <cctalk at gtaylor.tnetconsulting.net> Subject: Ethernet names...

by jnc＠mercury.lcs.mit.edu

> From: Eric Smith > 3 Mbps was sometimes referred to as experimental Ethernet, but AFAIK > the only official name was "Ethernet". > The best way to refer to it is probably "3 Mbps Ethernet". I was trying to remember what we called it at MIT (which had one), but my memory was hazy, so I want back and looked at the sources for the packet switch I wrote (which supported the first Ethernet, before the 10Mbit version even came out), and I found (slightly to my suprise) that it was "3Mbit Experimental Ethernet", or just plain "Exerimental Ethernet". (Of course, that was just MIT - other sites may have had different terminology.) No doubt we renamed it once the 10Mbit version showed up - I can probably search for early versions of the code to confirm this, if anyone cares. Anyway, I'd vote for the latter, short name. > From: Bill Degnan > See where wizards stay up lote by Katie Halner and matthew lyon. Interesting! It looks (from the Notes) like this was gleaned from an interview with Metcalfe, and she was _very_ careful (I helped her with the technical details - you can find me in the Acks), so I'd tend to believe it. My _guess_ is that was his early, 'in his head' name for the thing, and when they set out to actually build it, it was re-named 'Ethernet' (as Al's memo search seems to indicate). Noel

Looking for HP 1000 A990 backplane jumper board and memory frontplane

by glen.slick＠gmail.com

I have an HP 1000 A900 20-slot box with a working 4 card CPU set (sequencer, data path, cache control, memory controller). I also have a 12990-60102 A990 CPU card that would replace the 4 A900 CPU cards and install in place of the A900 memory controller card. What I don't have is the 12990-60020 jumper board that would install in the A900 backplane instead of the A900 sequencer, data path, and cache control cards, nor a 12230-60001, 12230-60002, 12230-60003, or 12230-60004 memory frontplane to connect the A990 CPU to one or more memory array cards. I'm not very hopeful, but is there any chance anyone on the list happens to have a spare HP 1000 A990 12990-60020 jumper board, and/or a 12230-60001, 12230-60002, 12230-60003, or 12230-60004 memory frontplane that they would be willing to part with? Not expecting these for free. These might be parts that 360 Technologies had before they recently closed up shop, although if they did they probably expected business critical prices for them. (For reference, the HP Museum site has a copy of the HP 1000 A990 Upgrade (HP 12990C) Installation and Service Manual, 12990-90011).

PDP-11 in russia?

Someone has contacted me about a pdp-11 that controls a "measuring machine dea epsilon". It appears that they want to replace the pdp-11 with a "ibm" (I'm guessing a pc), and then they would give the pdp-11 as a gift. That is all the info I have. Are there any listmembers in Russia who would be able to take on a project? J

6809 Monitor

by guykd＠optusnet.com.au

At 12:24 PM 2/10/2018 -0700, you wrote: >Does anyone have source to a 6809 monitor program? > >I'm looking for something I can make work in a CoCo. > >Functionality I'm looking for is something that will let me read and >write to memory. Attached is the zipped C source code for a 6809 monitor I wrote in the early 1990s. Compiler used was HiTech C. Build files included. It worked, but of course 'there may be bugs.' :) It's fairly generic, so not many changes needed for other CPUs. I also did an 80C196 ver. If the zip file attachment fails, it's online here: http://everist.org/texts/6809_Mon_V2.zip Doco from the MONITOR.C file: /* File: MONITOR.C For machine: Dual 6809 game board. Compiler: Hitech 6809 C. Written: Guy Dunphy, 4/9/94, derived from an earlier version. (by me) This file contains all code for a versatile serial monitor. It is event driven, and time sliced, so it can operate in the background with other CPU tasks. All data is stored big-endian. All serial I/O is via the functions aux_get_ch(), aux_put_ch(). Serial Tx is polled, while Rx can be either polled, or buffered interrupt driven with hardware handshaking (via RTS). See monitor_init(). This monitor can be used in multi CPU systems, where only one CPU has a serial comms interface, and each has different IO/mem maps and codespaces. If there is a means for passing strings between the CPUs, then the one with serial IO is used to run a 'master' copy of the monitor, and the other CPU(s) runs a 'slave' monitor version. The master CPU does all command line entry/edit operations, and can be set to pass complete command lines on to other CPU(s). It also will echo text returned from the slave CPU(s) to the serial interface. To use this file:- * For single CPU operation, just compile it as is. * As a 'master' (talks to a slave), predefine symbol MON_MASTER. * As a 'slave', predefine symbol MON_SLAVE. Monitor commands (See also mon_help_text[] ) ---------------- Multiple cmds allowed on a line, use ';' to separate. Upper/lower case of commands and parameters is not significant. A 'range' may be:- start start end start length (Shorthand form: if length is small and < start.) start L length space (as 1st char) Repeat last command. Execute or re-edit. tab (as 1st char) Repeat 'saved' command. Execute or re-edit. tab (not 1st char) Copy cmd to 'save' buffer. esc (as 1st char) Allow re-edit of following 'repeat' cmd. (... twice ) Kill 'pass cmds to slave' mode. D range Dump mem. D (no other chars) Dump another 64 bytes F[W][I] range data Fill memory. W=word, I=increment. G addr Go (call) to addr M start [data]... Modify mem. data ::= hex_byte | string | char string ::= "text" char ::= 'c R [reg_name = value] Optionally modify register(s), then display all regs. reg_name ::= cc a b d dp x y u pc Z [flag_val] Zot! Set operation mode. Bit flags set are:- b0 Halt system (no return from monitor). b1 Inhibit serial echo. b2 Inhibit serial prompt output. b3 Inhibit all monitor output (incl help). b4 Pass all cmds to slave CPU. ESC,ESC to exit. Examples:- Z Re-initialize monitor. Lose trailing cmds. Z 0 Restore normal operation, continue. Z F Just accept commands, no system, echo, etc. Z 2 Normal, but no echo (ie half duplex). S1ccaaaadddddd....ddss<CR> Motorola data record. Load to memory. Each hex line is treated as a command, so there is no special 'load' cmd. Before sending hex, best to do a Z6 or Z7 to stop all other time consuming tasks. When finished, do a Z 0 to restore normal ops. An ASCII ACK ($06) is sent when line processing is complete and no error found. This can be used as an acknowledge. If an error is found, a '?' is returned. See s19_decode(). S0.... and S9.... Header and end records: ignored.

pdp-11/34 extravaganza

by jwest＠classiccmp.org

I was contacted about an 11/34 system available. It appears to be not just a system, nor just a system in a rack, but pretty much a full installation and all the trimmings (printers, terminals, documentation, media, etc.). I am pretty sure some of the terminals will invoke interest at the very least ;) Note - the person who has it is looking for a sale. No prices have been discussed, but my impression is they aren't going to let it all go for $50 :) The stuff is located in the Detroit metro area. I am not (nor do I want to be) involved in this transaction in any way. I'm just passing it on. I would prefer to pass it to someone who has a demonstrated ability (and resources) for rescues of this size and type of equipment. All I care about is that the equipment is rescued and by a responsible party. Do not email me expressing interest in just one or two items. I will pass it all to one person - if THEY want to part it out *after the deal* that's fine. I do have a single picture I can forward. If interested email me directly..

Computer books and PC parts clearance

by dave＠mitton.com

On this list, about 2.5 years ago, I offered up a bunch of misc computer books, PC parts, and software, for the cost of shipping, but then I got occupied with some other parts of life, and didn't follow through with those that responded. I still have the emails and will let those that answered before get first dibs. I will follow up with them in a day or so, if their emails still work. But I have added more stuff to the list, including some misc hardware bits. The current list is on http://dave.mitton.com/computer_clearance.html I will give priority to the first, but if you don't come through with pickup or shipping costs, they will go to the next in line. I am hoping to move this stuff out in the next few months. Thanks for your patience, hope some of this is useful. Dave. Sent from Mail for Windows 10

I have two of them (long in storage in the house, but they ran when I pulled them from their Unitote/Regitel rack a couple of *decades* ago. There is an RDOS - disk images, available at: http://simh.trailing-edge.com/software.html (Top entry in the list) It is about a 2.5MB disk image. I suggest that you might download SimH and that image, configure SimH as a straight Nova (rather than a /3 or /4) and see if it runs that image OK. If so, there you go! Beyond that, I *might* be able to help, but it will depend on what the status of copyright is on what I have, and whether your system can even run what I do have. I am looking into the copyright part of it - that may take a week or two. (This is something I needed to to anyway). In the meantime: Do you have a way to *write* a tape image? I have an AWS format image of an RDOS starter system. Note, however, that the label on the RDOS starter image I have suggests it may only be appropriate for a NOVA 3 or NOVA 4, so it might not run on your system. So, I'd have to take some time to boot it and try and set up a system for a straight Nova. As this would take several hours, I'm not keen on doing that unless you know that one from SimH will not work for you. I also have some OS and compiler DG floppy images, if you have a DG-compatible floppy setup. Several different operating systems there. Same issue: one would have to see how many are compatible with a straight Nova. I have images of the floppies. Diagnostics for DG systems are notoriously difficult to find. I have a few, in listing format. JRJ

What platform can run m68k COFF binaries?

by ethan.dicks＠gmail.com

Hi, All, I have a backup of some old code that I thought came from a Sun3 machine, and indeed, there _are_ binaries on there, in a directory 'sun' that _do_ run on a Sun3, verified under emulation with "tme". The part that puzzles me is the collection of object files and binaries in the directory above that. 'file' tells me that they are "m68k COFF" files. From what I've read so far, COFF binaries are from System V Release 2-4. What I can't reconcile is what they might have been compiled on. Is it possible these were made for A/UX? The relevant file dates (late-1988 through mid-1989) do overlap availability of A/UX version 1. If these are for A/UX, it would be handy to verify this, then it would be more handy to be able to run them (I have source for some of this but I'm having problems getting modern C compilers to digest 30-year-old crufty code, and for a couple of the utilities I need, there is no source). I'm reading of a "shoebill" emulator. Anyone have any experience with it? Additionally, I'm reading that FreeBSD has a binary compatibility layer for COFF but I wonder if that's for Intel binaries only or if it extends to m68k. I have a lot of experience with UNIX but my thinnest amount is in the m68k arena (mostly some dabbling on Sun3 workstations and a Perkin-Elmer 7350). Thanks for any pointers or tips. -ethan

Vice News September 25th 2018

by alan＠alanlee.org

(cross-posed to cctalk, vcf-midatlantic, and AHCS lists) Imagine my surprise when I was catching up on my daily Vice News diet today - watching today's and yesterday's episodes - when VCF Mid-Atlantics's own Corey Cohen, InfoAge, and a VCFed banner popped up! They did a story on an auction house and verification of an original Apple 1 board up for sale. They called on Corey and his expertise to verify the condition of the board! Way to go Corey! If you want to check out the segment, I've hosted it here: https://www.atlhcs.org/links/Vice_Apple_Auction.ts Enjoy! -Alan H.

More CRAY, ETC

by useddec＠gmail.com

I sorted about 15 or so more of CRAY and other supercomputer items today. Among other things were a bunch ACM Transactions on Mathematical Software and a ton of Parallel Computing booklets. There were probably 20 or more full CRAY folders. Also 6 or so CRAY "gifts", like a key fob, a semi circular blade and other items. He is not sure if he is going to keep them, and I have no idea what kind, if any offer I should make. There are probable 15 boxes of research papers, and he went to conferences almost everywhere. I figure I might get it all moved by Friday, then I'll have to go through it. Paul
