I will have to dig out he small computer handbook from the Dec section at smecc library and study up on it again! the brain cells are foggy! another nice go with to display with 8s is the DEC logic trainer We somehow ended up with a few of these... one goes next to a 8 the other in toys robots and trainers display and one for offsite which leaves one extra for trade!

I've got both, with the front panel-less version connected (on occasion) to the front panel version as an expansion box. 8/F is identical except for color. There was a memory expansion box for the 8/L that is reminiscent of the front panel-less 8/M, though it has four field switches on the front and no key switch (the 8/M just had a key switch and a SW switch).

DEC cartridge ID & ARTIFACS 440

by hilpert＠cs.ubc.ca

Does anyone recognise these DEC cartridges?: http://www3.telus.net/~bhilpert/tmp/deccartridge.jpg Any details or knowledge of what systems they may have been used with? They're definitely digital, note the logo on the nearer one on the right. I can't recall ever having seen them. They're associated in this instance with 80s-era biomed analysis. Also, anyone know what processor may have been used in a Becton Dickinson ARTIFACS 440 cell-sorting (FACS) rack? We're speculating there may be an embedded LSI-11. Rob and I are assessing some surplus/scrap equipment for rescue but haven't been on site yet.

Someone mentioned -12's and -15's? I don't (yet) need any -11 ones, although at some point, I might need an 11/20 one (I have a line on an 11/20 that spent a lot of time outside, so its front panel is sadly very faded). The thing we really need to find now is a source for the special switches that DEC used in the front panels of the machines of this generation. Electrically, they are just standard SPDT switches (usually two-position, although for some - e.g. Deposit/Start - they are momentary-contact spring-loaded); the real issue is the mechanical fastening, which uses a special front plate (albeit on a standard micro-switch body). I have a number of different ones in my machines, from various manufacturers, but I have had no luck tracking down new ones through the part numbers on them (they seem to be DEC part numbers, or adaptions thereof). I have asked a number of people, but nobody seems to have spares/extras. Anyone know of a source? Noel

Need Dos bootable 5 1/4" floppy with binary or hex editor

by jws＠jwsss.com

I just got a Compaq Portable 3 (286). I need to edit the contents of what will be the C drive when dos boots, though it probably doesn't have a file system on it. Anyway i'll need to boot up from a floppy because it has a pick r83 system on the C drive. Not sure what the system is, so fdisk and some simple tools like that would be nice too. Anyway any help would be appreciated. I'm searching for someone local with 5 1/4" floppies and blanks I can use, but if one has a disk i can get from someone I'd be glad to send compensation. For Pick folks (Mr. F15) I don't know the sysprog password, and need to null it out. I may pull the drive from another system I have that I do know the passwords for, but this new system I just got is working, and I'd like to log in and see what this system has and back it up. Pleasantly surprised it has an AST 6pack in the expansion (included) in the kit. thanks Jim

Hercules Graphic Station (HG1024) drivers or utility disks?

Hello All, My googlefu has failed me in trying to locate actual drivers for download for this card. This was a TIGA (34010) based card w/ built in VGA (so no pass through) with 1MB of VRAM and 2MB of DRAM. I believe there were DOS utilities, Windows 3.x drivers, and SW specific drivers (e.g. AutoCAD). OS/2 or NT drivers would be fantastic but I doubt they are out there. TIA! -Ali

Improved MSV11-P FMPS

by jnc＠mercury.lcs.mit.edu

So I have a busted MSV11-P, and I needed the FMPS to work on it. There is one online, but on my computers, it was extremely faint, and very hard (almost impossible) to read. So I have worked on it some, and I have a new version here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/MP01239_MSV11-P.pdf which I feel is much more legigible, and is also a lot smaller (3.5MB instead of 36MB). The default page size is quite small (I have no idea why, I didn't do the re-conversion to PDF, I don't have Acrobat), but if you blow it up to about 300%, it still has good resolution at that point, and it's quite readable - all the signal names, pin numbers, package numbers, etc are quite legible. It doesn't have as much resolution hidden away as the original, but for most purposes, it seems quite acceptable (in fact, more so in some ways, given the increased legibility). I was interested in producing something readable, and easier to manage, and I think this new version succeeds at both. For those who are interested in the details of what I did (because I've seen other FMPS scans with this issue, and it might help someone down the road), after first saving all the pages as individual images (like I said, I don't have Acrobat, so whatever I did had to be done with something else - and I'm not sure Acrobat can do what needed to be done to make them legible, anyway), I started out by trying to simply increase the contrast. That didn't do anything (at least, with my image tool). Looking at the page images under magnification, I discovered why: the areas of ink (lines, letters etc) were actually (in the scanned image) a stipple of white and black pixels, which together produced the (un-readable) light gray printing of the original. So the contrast enhancement knob didn't do anything - each individual pixel was already quite light, or dark. So I used something called an averaging tool (which takes small groups of pixels, and averages them together), with a small averaging box size (I used 2x2), which converted the ink areas to a uniform grey; I could then use contrast enhancement to bring the printing up. I then reduced most pages to 40% of the original size, since the originals were scanned at 600 dpi, in 8-bit/pixel grayscale, and were pretty huge. (I didn't go that far on a few pages - the PCB images - which could use the higher resolution. Also, if you want the full resolution, the original scan is of course still available.) In addition to making the images smaller, this actually increased the crispness of the printing, since the reduction sampling process got rid of a lot of the jaggedness that the previous steps had left. I finally converted the resulting images from 8-bit/pixel grayscale to 1-bit/pixel black-and-white; on inspection of the two side-by-side, this lost a tiny bit of definition, but I felt that the reduction in size was worth it, plus to which my image tool has compression for 1-bit/pixel B+W TIFFs, but not for 8-bit/pixel grayscale TIFFs, so I won doubly on the size.

DHCP on VMS/VAX

by isking＠uw.edu

Hi folks, ISTR that DHCP was introduced in TCPIP-5.1, which was included on the 7.3 hobbyist CD. But I have a 7.2 CD?. I've installed VMS on SIMH on a G4 iBook (because I can), but then I remembered (yet again) that 7.2 doesn't have DHCP, which is a pain with a laptop on WiFi. So I'm hoping to find either (a) the kit to install TCPIP-5.1 or (b) a 7.3 ISO image on a big enough pipe for FTP. :-) Can anyone help? Oh, and if you're looking for 7.2 (VAX) I have that?.

DEC Runoff to any modern format conversion - MORE INFO

by johnwallace4＠yahoo.co.uk

[massive snippages for brevity] Apologies if this is a daft question badly presented: has anybody mentioned, or better still looked at, DSRPLUS for this picture yet? I did have a quick look but may have missed it. It is, as the name suggests, intended as a bigger better version of DEC/DIGITAL Standard Runoff. Some variants of DSRPLUS are available through VMS freeware (some, e.g. freeware V6 and V7, appear to be available online and working). DSRPLUS might even already be available on one of the general-access VMS systems, for anyone who can't install it locally. It gets better too: a web search for "dsrplus documentation" (ie where is the DSRPLUS manual) doesn't quickly find a DSRPLUS manual but does quickly find a Bitsavers copy of the HSC50 User Guide, whose frontmatter says "This document was generated using DSRPLUS." Could be coincidence, but for someone looking for MSCP specs... Apologies if I'm in the wrong tree. Have a lot of fun.

PDP-12 Restoration at the RICM

by michael.99.thompson＠gmail.com

W contacted David Tumey about Teletype hammers. He will send us some as a donation. We put some heat-shrink tubing on to stop further damage. Warren repaired and tested the M706 Teletype receiver. We put it back in the PDP-12 and put the borrowed M706 back in the PDP-8/I. The donor brought another M706/M707 pair, so we tested them and then installed them. We have two working serial ports in the PDP-12. Warren is making an Arduino based programmable baud rate generator for this system. We ran more diags. The 8/I Instruction Test #1 & #2, and the random JMP, JMP-JMS, ISZ tests work OK. The LINC Tape-Quickie test and the Memory Address test fail after running OK for a few minutes. We tested all of the G221 Memory Selectors, and they are OK, so the memory address decoding is probably working OK. This may be a case where the processor is sometimes doing the wrong thing when comparing numbers, and the rest of the hardware is actually OK. Debugging this will be the project for next week. The donor dropped off more documentation, spare parts, LINC tapes containing the DIAL operating system, and an RK05 disk pack that likely contains OS/8. We will make image copies of the LINC tapes and the disk pack. -- Michael Thompson

DEC Runoff to any modern format conversion - MORE INFO

by t.gardner＠computer.org

Hi Thanks for all the ideas. Apparently there is nothing off the shelf; I have sent copies of one of the two manuals to three of us who indicated they would try something and will be happy to do the same for anyone else. AFAIK, DEC RUNOFF is only similar to other runoffs in that it uses a period "." at the beginning of a line to designate a command. Most . commands span the single line but some have multi-line and/or multi file implications. E.g. Something like .HL 1 Overview of MSCP Subsystem Converts to <h1 style="text-align:left;"> Overview of MSCP Subsystem</h1> Most of the conversions are obvious but some are a bit more complex, in particular the .require command which apparently assembles the chapter files into a book. .referencepoint command which is some form of anchor, perhaps for an index since so far it always seems to follow a HL command so maybe .HL 1 Overview of MSCP Subsystem .referencepoint overvw_mscp_sub Converts to <h1 name="overvw_mscp_sub" ID="overvw_mscp_sub" style="text-align:left; "> Overview of MSCP Subsystem</h1> With the ID being called from a Table Of Contents built to include the full name and page number It looks like a multipass converter would be the way to go. Anyhow this is a bit beyond my current coding skill but if anyone else wants to try a converter I'd like to work with them Tom -----Original Message----- From: Tom Gardner [mailto:t.gardner at computer.org] Sent: Thursday, June 04, 2015 10:47 AM To: cctalk at classiccmp.org Subject: DEC Runoff to any modern format conversion or DEC MSCP protocol specs Hi I have multiple DEC Runoff (.rno extension) files for the manual on DEC's MSCP protocol.

Troubleshooting a N* Advantage

by snhirsch＠gmail.com

My Advantage decided to stop booting from floppy disks (the only media it is capable of booting). At first it threw random disk errors, then progressed to the point where I get an immediate "Hardware Failure" diagnostic on screen at power up. If I reset and hit 'Enter' it starts the disk drive comes right back with a "?" prompt and LOAD SYSTEM. I've checked the obvious: - Power supply voltages are good - Pulled, cleaned leads and re-seated 52 very tarnished 4116s - Cleaned and reseated all other socketed parts. A lot does seem to be working. Display is fine. I can enter the mini-monitor and poke around. Keyboard is being read properly. I accidentally found an undocumented diagnostic (enter mini-monitor with Ctrl-C and enter 'A'). This displays the disk controller status registers. The only activity is the sector mark pulse, so something is responding to disk data. Any advice from other Advantage owners or those familiar with the beast would be appreciated. Interesting data point: I replaced the 8035 slave processor with a newer 8035 from the parts bin and none of the I/O operations it manages worked at all - no keyboard no disk activity. Is there perhaps something special about the older part? I'm not aware of any major differences in this part through the years, but you never know. --

PDP-8/e front panels.

by rodsmallwood52＠btinternet.com

Hi Guys Thanks for all of the enquiries for panels. I have ten in total. One I have here (as in photo) and the other nine are in the drying rack at the silk screeners. My photo does not do them justice. The screening is a lot sharper and clearer. On Monday I'll go and get the rest of them (10mins down the road) and sort out shipping. I'll let one of the nine go to each of the first nine firm orders. Please send your order to me at rodsmallwood52 at btinternet.com. I'll respond with the total inc. shipping. Payment will be by PayPal. and I'll ship on receipt of payment in full. I'll also instigate another batch of ten. The plexiglas suppliers size the panel and do all the cutouts. They then ship direct to the silkscreeners who are (very) local to me. Total time to second batch availability circa 7-10 (business) days. If I get orders for more than ten then I'll bump up the second batch size accordingly. If there is a demand I'll do other 8's or 11's front panels that use the same plexiglas and silk screen technique. R & D (maybe ware) 8/e bezel in cast resin 8/e programmers console PCB ( If I can solve the problem of the Stackpole switches availability.) 8/e Microprocessor PCB addon to run an 8/e simulator with serial i/o to a terminal.

PDP8/e front panels.

by rodsmallwood52＠btinternet.com

Hi All I have recently produced a number of high quality custom PDP8/e front panels. They are full size reproductions of the original. The production methods are exactly as used in circa 1971. They are not photographs. The front has the two colours plus the white each done with its own silk screen and the back has the intense black with the clear circular areas for the lamps to shine through. The inks were matched and made to order. The acrylic blanks with the cutouts for the keys were also a custom order. I did the artwork, The four screens were made and the printing done by two young ladies with very good graphic arts skills at 'Squegee & Ink Ltd' local to me here in Newbury UK. I have some photos but they do not do justice to the pin sharp lines and intense colours. The panel fits the bezel and the switches on the key + lamps board line up. I have a few to sell and can do more if needed. Due to the custom production they will not be low cost ($95.00 + shipping from UK) If you are interested I'll send you a picture. My photo skills are not that good. Rod Smallwood

VMS EXCHANGE format for VAX console media

by nf6x＠nf6x.net

I have a copy of an 11/730 console tape which I have been told is in EXCHANGE format as created by the CONSCOPY utility. Can any of the VMS experts here help this VMS noob learn how to translate that into a raw block-level image of the corresponding TU58 tape, which I might be able to use with a TU58 emulator? I see that the EXCHANGE image is 512 bytes longer than a full TU58 tape. Could it be as simple as chopping off the first or last 512 bytes? I'm not quite at the point yet where I know what a console tape ought to look like in a hex editor, so I can't clearly see whether that might work yet. I'm presently starting to work on getting some version of VMS running on an emulated 11/780 under simh. So with any luck, I may have a functioning VMS environment before too long, even though I haven't managed to boot up my real 11/730 yet. My end goal is to use that console tape image with some TU58 emulator to boot up my real VAX. I have some original console tapes for it, but they no longer seem to be readable. I did get my machine to examine one of them quite a bit before deciding it wasn't suitable, so maybe there is still some recoverable data on those tapes... but none of them seem to be sufficiently error-free to boot my machine. I'm presently working on booting it from a downloaded console tape image, but getting tu58em and my 11/730 to like each other is still an ongoing project. Once I get there, I think that this EXCHANGE format image that I have is the same console tape version as my unreadable real tapes, and newer than the other downloaded image that I'm presently trying to use, so it would be nice to be able to get it into a format that I can use directly. Thanks in advance for any clues! -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

DEC Runoff to any modern format conversion or DEC MSCP protocol specs

Distribution panels (cab kits) for DZV11/DZQ11

by jnc＠mercury.lcs.mit.edu

> From: Glen Slick > There is this distribution panel on eBay at the moment, but I think > this might be the H3173-A version for the M3104 DHV11 / M3107 DHQ11 Yes, it is - I got several of those from him, but he only had one of the DZV11/DZQ11 ones (which are, simply by looking at them, indistinquishable >from the DHV11/DHQ11 ones - one has to look at the part numbers to distinguish them, they are so similar - well, to be hyper-precise, there are two variants of the DHV11/DHQ11 one, one with the Berg on the side, and one with the one of the top, and it's the latter which is visually almost identical). > The 70-19964-00 distribution panels I have for the M7957 DZV11 / M3106 > DZQ11 have arrows screened on to the front of the panels between the > DB25 connectors. (I'm not sure what the arrow is supposed to indicate). Which way around to install them, or which port is #0, would be my guess. I've seen a similar arrow on the dist panel for the DLV11-J (which also comes in two distinct variants). Noel

PDP-11/44 M7098 ECO #7?

by mattislind＠gmail.com

I have been given a PDP-11/44 and I was running through all sorts of diagnostics to check out the machine. It seems to work fine except for the trap test KKABD1 which fails at 23252. It passes an earlier version of the same trap test. The listing (thank you J?rg) is at: ftp://u58104846-pub:open4you@ ftp.j-hoppe.de/fichescanner/bw/gh/AH-F623D-MC__KD11-Z__11-44_TRAPS__CKKABD0__(C)79-82.pdf It tells me that my M7098 board is missing ECO #7. Anyone knows of a list of ECOs for the PDP-11/44. I think I have searched everywhere I can think of but haven't found it.

Two more P112 kits left

by dave＠661.org

I have two more P112 kits left. One is a board with parts. The other adds an old SCSI enclosure. Once these are gone, it'll be a long time before I offer complete kits again. The price is $190 for the kit alone and $210 for the kit with chassis (shipped in the US). The chassis is identical to the blue sparkly one seen at https://www.flickr.com/photos/32548582 at N02/sets/72157649945208099 except it's beige. -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

Distribution panels (cab kits) for DZV11/DZQ11

by jnc＠mercury.lcs.mit.edu

Hi, all, I'm looking for distribution panels (cab kits) for DZV11s/DZQ11s - or that wierd cable with the DB25 connectors on one end which substitutes for a cab kit, the BC11U - for the DZV11/DZQ11. (The part number for the distribution panel is 70-19964-00.) (I'm pretty sure the cabkit, which is technically for the DZQ11, will also work with the DZV11, since they are documented as both using the BC11U cable.) I don't have to have the cable (which is a BC05L-xx, which I'm pretty sure is the vanilla 40-pin cable), since I'm set up to make them, although if the panel comes with one, that's fine, of course. Anyone know of a source for any? I looked online, none on eBay, Google showed one dealer with one, but they wanted like $50 each. Noel

8-bit Computer TV Channel Use

I don't recall a previous discussion of that, but my lack of recollection certainly doesn't mean that it never happened. It's been mentioned recently on various retrocomputing podcasts that many (most? all?) of the existing solutions out there work poorly with some vintage computers, particularly the Apple II. It was mentioned in passing on Open Apple #43 in the discussion of LCD panels suitable for an Apple II GS laptop conversion, and specifically discussed on RCR #100 in the Host's Topic segment as something lacking in the market (links below). Maybe there are good solutions that just aren't well-known in those circles? If so, I'd like to hear about them. I'm also very interested in learning about specific instances of "computer X worked poorly with adapter/display Y, and it failed in this particular way". While I recall hearing multiple mentions of this sort of trouble in general, I'd like to hear of specific examples of how specific combinations failed, i.e. "monitor Y couldn't sync to video from computer X", "adapter Y generates monochrome output instead of deliberately aliased colors from computer X", etc. http://www.open-apple.net/2015/01/22/open-apple-43-january-2015-happy-new-y… http://rcrpodcast.com/episodes/2015/5/10/rcr-episode-100.html -- Mark J.

Datasaab D12

by pontus＠Update.UU.SE

Hi Yesterday I picked up a Datasaab D12. Which I didn't know existed until then. Pictures here: http://imgur.com/a/vPTZw It's a small desktop computer intended for small business accounting and invoicing. It's built arround an intel 4004 and has room for expansion cards for memory and "customer roms". The service guide mentions a "two level" environment with a "basic" level and a "customer program" level. I'm hoping it means there is a Basic interpreter but I'm not convinced. The manual also mentions a "D12 assembler" as the develoment environment. It's apparently a subsystem that comes in a nice attache case: http://imgur.com/QQUrcGh It's actually made by Facit and may go under that name. Does anyone know more or have manuals? Regards, Pontus.

Panaplex display history

by jules.richardson99＠gmail.com

JOOI, does anyone know when Panaplex 7-segment displays started going the way of the dodo, to be replaced with LED displays (and, on the back of that, what were the advantages of a Panaplex-type display over an LED one?) I just saved a few boards from a dumpster with such displays on (they're actually Beckman ones, not Burroughs), but I was a little surprised to see IC dates into 1981; I thought by then things had moved over to LED. I'm almost certain that they're from old gas pumps - maybe the displays are just more readable in bright sunlight than LED? (there's a sticker on one of the PSU boards with a 'shipping date' in 1999) cheers Jules

PDP-12 Restoration at the RICM

by michael.99.thompson＠gmail.com

We spent Friday and Saturday debugging the PDP-12. We replaced a bad SN7400 driver chip and three bad bulbs in the front panel. We can now trust what we see on the front panel for debugging information. We tried some of the PDP-8 and LINC instructions and noticed that some of the bits in the Instruction Register were stuck on. We swapped the two M216 (six flip-flops in three SN7474 ICs) flip-chips that make up the IR and the stuck bits moved. We replaced the broken M216 with a spare, and now all of the IR bits work correctly. With a working IR, we found that lots of the PDP-8 instructions, and many of the LINC instructions now work. We can turn the relays on and off and make noises through the speaker. During other DEC restorations we have replaced LOTs of SN7474 ICs. We pulled all of the M216 flip-chips and ran them in Warren's tester. We found and replaced another bad M216, the one in slot E8 that controls the core memory states. Now core memory works! We went through the troubleshooting guide in Maintenance Volume-II. It has a procedure for doing a quick test of core memory that revealed a problem in the upper addresses. From looking at the prints it had to be one of two G221 flip-chips. We swapped in a spare and found that the one in slot C09 was bad. Now all of the first 4k of memory works. There is a problem with any PDP-8 instruction that has an address in the lower 9 bits. All 12 bits of the instruction are used, so it makes a mess. Debugging that issue will be the next project. -- Michael Thompson

Apple-1 doh!

by chrise＠pobox.com

http://in.reuters.com/article/2015/05/31/usa-california-computer-idINL1N0YM… May 31 (Reuters) - A $100,000 check is waiting for a mystery woman who donated a rare Apple 1 computer to a Silicon Valley recycling firm. CleanBayArea in Milpitas, California, is trying to track down a woman in her 60s who dropped off some electronic goods in April, when she was cleaning out the garage after her husband died. In one of the boxes, buried under worthless keyboards, personal computer pieces and wires, was a 1976 Apple 1, a groundbreaking home computer. Apple co-founder Steve Wozniak designed and hand-built the computers and sold them for $666.66 each. Only a few dozen are known still to exist. [...] -- Chris Elmquist

Looking for a Northstar S-100 Double Density Controller

by spereira1952＠comcast.net

I'm looking for a Northstar double density floppy disk controller. The double density controller will be marked as MDS-ADx. I have seen pictures of this board marked as MDS-AD and MDS-AD3, but I'm not certain how many different versions there may be out there. Obviously, I would greatly prefer to know that the board is operational prior to shipping. Please let me know if you might have a spare or unused board that you would part with for a reasonable price plus shipping. Thanks! -- Stephen M. Pereira Bedford, NH 03110 KB1SXE

UA11 "Unibus Analyzer" Wanted

by pbirkel＠gmail.com

I didn't discover this wonderful project from Guy until *after* he had moved. And while he _may_ have a few boards left, they're still buried somewhere in his amazing collection of "materiel" :->. As I need to learn/work my way through various Unibus systems/scenarios ... starting with self-education ... I'd very much like to acquire one of these beasties. Does anyone have a UA11 PCB, kit, or completed board, with which they'd be willing to part? A good home with a friendly family is guaranteed! Many Thanks, paul

Bitcoining on a 1401

by marc.verdiell＠gmail.com

We do have two 1401s, and on a good day, they both work. No working 360s. But even if we could have the two 1401's talk to each other, it would still take about the age of the universe to mine a block. This is about the worst machine for scientific calculation, as it does BCD, character by character arithmetic, in a serial fashion, one BCD digit at a time. Hardware multiplication is an optional add-on feature on these machines (which we have)! So no, you can never mine a real block in time with a 1401, or even a million of them. But that you could implement and run the algorithm is just a testament that the fundamentals of computing haven't changed, doubled with a vivid demonstration of the mind-boggling effects of Moore's Law over one generation. And having old hardware tackle modern tasks is just plain fun. And, lest I forget, a credit to the skill, talent and humor of our vintage programmer extraordinaire Ken, who joined us recently.

OT: Looking for the Tek 465 of Logic Analysers

by marc.verdiell＠gmail.com

I'd suggest to go for the king of the hill at the time, and get an HP 16xx (163x, 165x, 166x, 167x) for all-in-ones or the 16500 if you like to modularize yourself, although tis latter one is much harder to put together since you have to get the frame, the plug ins, the software, etc... On the 16yx, the higher the y number, the better the machine (i.e faster, better screens, more memory). They are widely available, starting at below $100 for the earlier machines, and up to $300-$400 for the later ones. I'd recommend to have at least one that has a hard disk, so you don't have to find or make an old LIF floppy to boot from. As always the rub is the pods/probes. I had to complete my set separately, but they are also widely available. This is a relatively small amount to pay for what these machines actually are. The later ones have the inverse assembler for the 68000. I got the luxury one, a 1670G with the pattern generator (which I haven't found an excuse to use yet).
