DEC Pro hard drive formatter

by paulkoning＠comcast.net

I'm wondering how to do hard drive formatting, which is likely to be needed when working with emulated disks in David Gesswein's MFM emulator. As far as I can tell, RT-11 can do this. At least I have a source code printout for such a formatter. But while I can find a hard drive image of RT V5 for Pro, I haven't found any floppy-bootable images. And I think it's a bit tricky to create one. I knew, long ago for V2... Any suggestions? Any alternative sources for a formatter? I guess I really should consider typing in the core of that formatter and adding it to RSTS. paul

ICL PERQ 2 T2 Micropolis 1303 spinning down.

by mattislind＠gmail.com

I have a nice ICL PERQ 2 T2 that I am going to start working with now. First thing was to try to image the hard drive. It is a Micropolis 1303. It spins up but when it reaches what I think the correct speed it immediately spins down. Usually I think there would be a click and then the heads would recalibrate. But there is no click and no head movement. I really would like to make an image of the drive. What are your thoughts? Are the heads sticking? Some kind of solenoid that is not releasing the heads? Not properly up to speed? (but it sounds like the speed is right) /Mattis

Nine track file marks, Burroughs

by drb＠msu.edu

Folks, I've now seen two Burroughs tapes where some of the expected file marks between labels and file data were apparently missing. I think a reasonable description of these is "Burroughs/Unisys B6x00 'Library/Maintenance' tapes with ANSI-69 labels" Reading drive is a Cipher GCR Cachetape with SCSI interface The one I read yesterday read in streaming mode and reported no read errors. I tried re-reading it today, and it read in start-stop mode, but still didn't have the missing file marks. (It also encountered a few errors, and eventually ended up sticking to the head, this time. Guess that bake cycle was a one-shot, which isn't a surprise.) This tape is a "Burroughs Series 7 / 100% Tested / 3200 FCI" 1200 foot reel written at 1600 BPI in 1986. Here's the beginning of the tape: file 1 record 1 size 80 00000000: e5 d6 d3 f1 f0 f3 f6 f1 f3 f0 40 d7 d9 d6 c7 d9 VOL1036130 PROGR 00000010: c1 d4 40 40 40 40 40 40 40 40 40 40 f6 f5 f3 f0 AM 6530 00000020: f3 f0 f5 f0 f3 40 40 40 40 40 40 40 40 40 40 40 30503 00000030: 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 00000040: 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 f1 1 file 1 record 2 size 80 00000000: c8 c4 d9 f1 c6 c9 d3 c5 f0 f0 f0 40 40 40 40 40 HDR1FILE000 00000010: 40 40 40 40 40 d7 d9 d6 c7 d9 c1 f0 f0 f0 f1 f0 PROGRA00010 00000020: f0 f0 f1 f0 f0 f0 f1 f0 f0 40 f8 f6 f2 f0 f2 40 001000100 86202 00000030: f8 f6 f2 f3 f2 40 f0 f0 f0 f0 f0 f0 f0 f0 f0 f0 86232 0000000000 00000040: f0 f0 f0 40 c1 f9 40 40 40 40 40 40 40 40 40 40 000 A9 file 1 record 3 size 80 00000000: c8 c4 d9 f2 e4 f0 f1 f0 f2 f4 f0 f1 f0 f2 f4 f3 HDR2U01024010243 00000010: f0 f1 f0 f1 f0 f0 f0 f0 f3 f0 f0 f0 f0 f0 f0 f0 0101000030000000 00000020: f0 f0 f0 f0 f0 f6 f4 f0 f0 f1 f3 40 f0 f0 f6 f4 00000640013 0064 00000030: 40 40 f0 f6 40 40 40 40 40 40 40 40 40 40 40 40 06 00000040: 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 file 1 record 4 size 2070 00000000: 40 00 00 00 00 01 00 00 00 00 00 00 12 03 03 04 ............... ...etc. Is oddness with file marks something others have seen with Burroughs tapes?

PDP-11/34 /04 power knob anyone?

by fritzm＠fritzm.org

Hi folks, I?m working on an 11/34 at the moment, with the programmer?s console, and it is missing its front panel power control knob. I think it is the same one used on the 11/04? Anybody have a spare in their parts stock that they?d be willing to part with? (I?m also missing the plastic half-panel for the front, but I do see those go by on eBay from time to time.) cheers, ?FritzM.

cc:Mail Router for NT

by tomas＠basun.net

Hi all, I'm using a HP 200LX to connect to a cc:Mail installation, with a null modem cable. It has worked better before, but now I don't seem to be able to connect at all. This is the output from the router, when trying to connect from the 200LX: | C:\CCMAIL\Router>C:\CCMAIL\Router\NTROUTER.EXE C:\CCDATA MODEM/PBX COM1 DIAGNOSTICS/F LOG/C:\CCMAIL\Router\ROUTER.LOG | cc:Mail NT ROUTER Version 6.10.00.4 | Copyright (c) 1986, 1997 by cc:Mail, Inc.

Here is the modem file: | [attributes] | MODELS=Null | NULL MODEM=1 | [commands] And another thing is that I only seem to be able to get a response at 1200 baud (the router default) by not specifying a speed when starting the router. If I add the speed to the command line (the first line above), any speed, (and the corresponding setting on the Palmtop) then there is no connection at all. It has worked better earlier. I managed to connect at 9600, but that was a different PC. I am not aware of having changed anything relevant on either PC or Palmtop. Any help appreciated. /Tomas

Rod Coleman's personal history of founding, building & running SAGE

by lproven＠gmail.com

This may be old news -- it was new to me, though. https://suddendisruption.blogspot.com/search/label/Booting%20Sage%20Computer I'm not really familiar with SAGE machines. They were not as well-known in the UK, I think, being upmarket from the Apple ][ and IBM PC, both of which were eye-wateringly expensive by UK standards of the time. Also, they were terminal-based things and even back then I was interested in boxes with graphics. :-) -- Liam Proven ?

Can someone check to see if a RQDX2 used the Western Digital chips to interface to MFM drives?

Keyboard storage, part 2

by aperry＠snowmoose.com

An update on keyboard storage, which I asked about here last month. I ordered some USPS Large Flat Rate Priority Mail "board game" boxes. This is a size not usually available at the post office and come 25 in a pack. They are a good size for mailing (and I am glad that I ordered them so I can use them for that), but I don't think they work for keyboard storage. They are so much larger than the keyboards that I am storing that lots of packing material is needed so they don't move around. Also, they are designed to be sealed and shipped, so there isn't a convenient way to open them once they have been closed. Next, I ordered the Uline keyboard boxes. I had to get 25 of them and they are not free ($2.70 per box plus tax and shipping). They can be open and closed. They are a much closer to the size of a keyboard (surprise, surprise!) so not much packing material needed, but they are slightly smaller than a Sun Type 5c (as well as Axil) keyboard and needed to modified for those two. No modification needed to store a Sun Type 4 or CompuAdd Sun-compatible keyboard in one. I haven't tried a Sun Type 6 yet. To anyone in the Seattle area that need keyboard boxes, I will probably have 10-15 of them once I get all of my keyboards packed. If you would like any, let me know. alan

I've not seen anything in any provider's terms of service that say anything about what type of email they receive, save for exceedingly few categories; child porn and illegal activity among the short list. I have yet to see anybody state that sending an email to an invalid email address and (potentially) receiving a bounce is illegal. So, again, no grounds for Google to do anything.

Ouch, but 2 Perqs out.

by cz＠alembic.crystel.com

This was a long day. Went over to the house and started working on getting the Perqs out of the basement. I've been moving smaller stuff to make room and it was time. First up was a Perq1 chassis that just had the big disk drive in it, side and rear panels. I figured it was lightest and after taking off the sides and top was able to lift it and carry it up steps. Still heavy and bulky, but it made room and a path to get to the second one. The second one was a mess but a lot heavier: It still had the card cage in it and I was not going to be able to lift. So I figured out how to take the sides, top, front, back, and bottom (pounds are made of ounces) and then spottted the screws that hold the card cage and power supply in the box. Bless the people at perq, those two screws out and you can lift the cage out the side of the box. The card cage without cards (took them out to lighten) was heavy but I got it up the steps. Then with a herculean amount of effort I managed to carry the rest of the box up, followed by the sides, top, front, back, and bottom plates. There are still two more Perqs down there. They have heavier front plates (I was able to take them off) with real shielding. They were different designs, so they were not Perq1s and they are not the same as each other. Question: Are there any pictures of other types of Perqs? Unfortunately they are still buried under old Sun gear and a Vaxserver of some sort. So I'll have to think about those, but they will need to come apart as well. Question: Do the card cages and stuff come off the later Perqs as well? Also got two different types of keyboards that say Perq, and a monitor that looks like a big fat white Vetrex and says Three Rivers. Question: What does a Perq mouse look like? At least this stuff will not be junked. I'll take pictures and such tomorrow and throw a tarp over everything tonight because I'm too tired to get it out of the truck. I swore off high-mass hobbies for a reason....

Rod Coleman's personal history of founding, building & running SAGE

by boris＠summitclinic.com

Probably read about this machine in Byte back then but was programming PDP-11's. Was very disappointed in IBM PC as IMO was far inferior to PDP-11 which was was easier to interface to data acquisition hardware and had a much nicer instruction set. Ran into 68000 processor for first time in 1986 when my father bought a 512 K Mac and couldn't believe performance of this CPU compared to PDP-11 - 24 bit addressing! and inferior memory access to what Sage had. Also, found 68000 instruction set very similar to PDP-11 and had no trouble writing assembly code for it a few years later and also really liked Apple's debug switch which was best implementation of a debugging system I've thus far run into. Weird that Rod Coleman had 68000 instruction set associated with IBM 370 whereas to me it was very PDP-11 like and 24 bit addressing was a very nice feature (that was one similarity to IBM 360) Other interesting aspect to SAGE history was the influence of September 1966 issue of Scientific American computer issue on Rod Coleman and lots of other people I've talked to. Was so glad that had this issue to read in 1966 and spent most of my time in boring school classes designing logic circuits and then building them at home using discrete DTL logic with parts salvaged from surplus IBM boards. Thanks for the link as didn't realize 68000 was used for home systems before I ran into Mac. >This may be old news -- it was new to me, though. > >https://suddendisruption.blogspot.com/search/label/Booting%20Sage%20Computer > >I'm not really familiar with SAGE machines.

Winsystems SAT-V40

by doc＠vaxen.net

I know this is a long shot, but I'm asking anyhow. I'm looking for the Ops Manual for a Winsystems single-board system. Model: SAT-V40 P/N: 400-0186-000 The SAT-V41 model is essentially the same board, so I'd settle for docs for that. There are references (from 2012) to SAT-V41.PDF, so I know it at least *did* exist in digital form. If anyone in the US has the paper manual I would happily scan it, and pay postage both ways. Thanks! Doc

dp8340n IBM 3270 protocol transmitter encoder

by wh.sudbrink＠verizon.net

Hi, In cleaning up my lab and stores, I have discovered that I have a tube of 10 of these chips. I'm not quite sure what they are for or were used in (or even where I got them). Anyway, if they are, in fact, for managing 3270 mainframe terminal traffic, they're probably not of much use to me. I've also noticed that I'm getting very low in vintage 4000 series CMOS chips. Anybody want to trade? Bill S. -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

MM11-F manual/prints available

by jnc＠mercury.lcs.mit.edu

I finally got around to completing the processing of the scanned images of the pages of the MM11-F manual and engineering drawings. A PDF is available here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/DEC-11-HMFA-D_MM11-F_Manual.… http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/DEC-11-HMFA-D_MM11-F_Drawing… For those who object to PDF/A, here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/MM11-F_Manual.tar http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/MM11-F_Drawings.tar are TARs of the original TIFFs. The images aren't that great, I see; the original paper copies aren't too hot, IIRC. If anyone actually has a use for these (does anyone out there _actually have_ an MM11-F?), and there's a problem, let me know, and once I get my scanner running again, I can try and get better ones. I thought we were missing the MM11-E manual, so since the two are so similar (most of the boards are the same) I thought the MM11-F's would mostly fill the gap, but it appears it's there, prepended to the MM11-E prints. One thing this set has which might be useful is the backplane wirelist (the MM11-E's seems to be missing); given the commonality of most of the boards >from the MM11-E to the MM11-F, they're probably very similar.

terminals-wiki?

by dfnr2＠yahoo.com

The terminals wiki (https://terminals-wiki.org) seems to have been down for several months.? I hope the maintainer is OK. Does anyone know if this site is gone for good??? Is there a mirror anywhere?? The wayback machine has a few pages, but mostly serves to capture the look&feel. Dave

Seeking: TMS32010 Assembly Language Programmer's Guide (1983)

by pbirkel＠gmail.com

All; I seek a copy (hard or electronic) of the "TMS32010 Assembly Language Programmer's Guide" (1983). Paperback : 194 pages ISBN-10 : 0904047423 ISBN-13 : 978-0904047424 Publisher : Texas Instruments (December 1, 1983) Item Weight : 1.11 pounds Language: : English The "TMS32010 User's Guide" (1985) is readily available. Not so the (more important!) Programmer's Guide :-{. I recently obtained a TMS 32010 Evaluation Module (EVM). So I'm motivated to "learn something" about the details of programming the TMS 32010. My first hands-on foray into the (early) world of DSP :-}. I've searched all of the nooks-n-crannies of the web to no avail. All help in locating/obtaining a copy of this document will be greatly appreciated. I do have a copy of "Digital Signal Processing Using TMS32010" (Douglas L. Jones) on order as a stop-gap measure. Thank you, paul

PDP-11/70 backplane wire list

by derschjo＠gmail.com

Hey all -- Discovered a broken wirewrap wire on the 11/70 I'm slowly working on, it's on the last slot (44), and runs from BD2 to ??. White wire, part of a white/black twisted pair. I've been looking but haven't found a wire list for the backplane -- anyone have any leads, or, alternately, does anyone have ready access to an 11/70 backplane to trace where the wire from BD2 on slot 44 goes to? (Fortunately it looks like there's just the one wire on that pin, though there might be one "below" it on the pin that I can't quite see, rather cramped in there.) Thanks as always, Josh

Emails going to spam folder in gmail

by billdegnan＠gmail.com

Hi, I have noticed the same email addresses' messages routinely end up in the spam folder of gmail. It's no big deal for me to check my spam folder but it's an extra step and messages can be lost. For those of you who run your own mail servers please consider updating your DNS / authentication to match gmail standards. It's not about making a filter or marking messages as "not spam". It's about how the sending mail server communicates with gmail and the "newer" mail server gateway protocols, etc. so that it's not necessary to make a filter in the first place.' There are a lot of how-to's on the web, each mail server is different and there is no simple fix that applies to all. Bill

DEC part number system

by jnc＠mercury.lcs.mit.edu

> From: Antonio Carlini > It was (iirc) described in DEC STD 012 (the part numbering standard) ... > I do have (or did have) a DEC STDs CD at one point, but my copy of that > seems to be missing DEC STD 012. ... I've no idea why this one might be > missing. It looks like you already uploaded it to Manx: https://manx-docs.org/collections/antonio/dec/standards/el-00012-00-0000.pdf Looking though that led me to DEC STD 012-2 "Unified Numbering Code for Part Identifier Class Codes": https://manx-docs.org/collections/antonio/dec/standards/el-00012-02-0000.pdf which was exactly what I wanted. It's not the thing I remembered, but as DEC's official list, in some ways it's better (although it's so detailed it's kind of overkill :-)! > From: Vincent Slyngstad > the "Spare Parts List" links on this page are relevant: Volume II had a brief but early 'class code' list; I made good use of it.

vtserver for geezer '11s

by jacob.ritorto＠gmail.com

Hi, I modified vtserver to work on pdp11/34 and similar - the older machines that have the 000000 000000 000000 000000 @ odt prompt. I'm afraid I didn't do a very thorough job (hack night and just wanted to get it working) and in retrospect I wish I would've made a conditional argument to put it in this mode. Perhaps we should collaborate on adding this properly and adding other desirable features like compression for incoming "all zero" blocks when pulling images in from real hardware, etc. It's here if you'd like to use it: https://github.com/jritorto/vtserver You can run it with ./a.out -odt to facilitate its talking to the pdp at power-on and loading its initial boot sequence via odt in octal. You have to run the primary bootstrap with L 140000 and S <return> because I botched the parsing a bit in my rush to get things going. thx jake

Hey, I got a Perq_T2 image!!!

by cz＠alembic.crystel.com

Well, after waiting almost a month for the USPS to deliver a "Priority Mail 1 day" package from Dave I now have the MFM reader card. So I started working on these disks I rescued. First up was a ST506 (labelled "RD50" by DEC) and a pair of ST412's. Bad news: No drives spun up Good news: You can take the controller board off the drives and spin the spindles by hand. Better news: The spindles spun (clockwise, viewed from bottom) Best news: spinning while powering on got all three to spin up. So far I imaged the RD50 (possibly a Rainbow or a Pro/350) and one of the ST412's. It came up as a PERQ_T2 format and I have two dumps of the disk with only one bad sector reported. Anyone know what to do with this kind of image? I've powered down the drives and will store them till I can figure out how to make them run more quietly.... C

ISO: TI 980 (not 980A or 980B) Hardware docs

by derschjo＠gmail.com

Hey all -- A straight TI 980 (not one of the later 980A or 980B variants) appeared on my doorstep this afternoon. While well-shipped, the person I got it from decided to ship the boards and power supply separately from the chassis -- and unfortunately didn't document where anything goes. There is precious little information out there about the original 980 -- anyone sitting on any documentation? Anyone know someone who has one? (Anyone have any spare parts? The core memory boards & chassis are labeled well enough for me to see that I'm missing one of the "DA" boards...) Thanks, Josh

PDP-8 memory card on eBay?

by jnc＠mercury.lcs.mit.edu

Anyone recognize this card: https://www.ebay.com/itm/313323417718 I looked, and it doesn't seem to be any of those for a PDP-11. However, I see the DRAM array is 12x4 chips, which makes me think it might be for a PDP-8? Noel
