q about PDP11/34 schematics (clock generation)

by bert＠brothom.nl

Hi all, Can anyone explain to me how the clock generation of the PDP11/34 works? I see in the schematics on page 1-5 that clock signals are "generated" (?) by a delay line. That is: the component is referenced as E104 and the parts list mentions it as "delay line 150nS" As I don't have any other info on this part, I'd like to find out how this component works. Appearantly there are multiple signals coming from this device. Please forgive me my ignorance, I think I might be to young to know (30). TIA Bert

Available: SCSI disks and SCSI DDS drives

by pat＠computer-refuge.org

We were emptying a cabinet of old disks at work, and I saved a few to erase and offer to the list. I'm asking $5 plus shipping costs for a pair of drives (except for 5.25" FH drives, as noted in list). Price can go down in quantity. :) All drives are 3.5", 50-pin SCSI unless otherwise noted. What's available: IBM drives: 9 x 2GB 1.6" tall/Half height (86F0118 / 86F0101) "Model 664" 1 x 1GB 1.6"/HH (55F9902) "Model 663" 2 x 1GB 1"/ 1/3H (45G9467 / 86G9049) "Model 662" Fujitsu drives: 1 x 1GB 1"/One third height (M1606SAU) 2 x 2GB 1.6"/HH (M2932SAU) 4 x 600MB 1.6"/HH (M2694ESA) 2 x 4GB 1.6"/HH (M2934SAU) 4 x 2GB 5.25" wide full-height (M2654SA) ($5 ea) 2 x 4GB 1"/HH (M2954SYO) Archive DDS drives: 2 x 5.25" HH internal DDS 2/4GB tape drive I want to get rid of the disks as soon as possible, so I'll only be holding onto them until around Jan 3rd.

[Fwd: Intel Pentium Overdrive EBOXP0DP5V83 Chips] (UK)

by julesrichardsonuk＠yahoo.co.uk

Chap has 11 of these critters still sealed in boxes - they take a 486 up to an 83MHz Pentium apparently. I suspect they're no use to anyone these days :) I can get them to Bletchley; can always park them in a corner for a while if needs be! They're off to the tip otherwise... cheers Jules

XXDP inventory (warning: long list)

by GOOI＠oce.nl

> I will scan the following three first as they describe XXDP *itself* : > > - AC-F053B-MC CXQUAB0 DECX11 USER'S MANUAL > - AC-F055C-MC CXQUBC0 DEC/X11 CROSS-REFERENCE MANUAL > > both of these are already on line at > www.bitsavers.org/pdf/dec/pdp11/XXDP Thanks Al, 3 less to scan :~) A question about the naming scheme of the files. As example, let's take this one: AC-E246B-MC CZRLEB0 RL01/RLV11 PERF EXERCISER According to bitsavers that would become something like this: AC-E246B-MC-RL01-RLV11PERF.pdf where the last part gives a brief indication what the xxdp is used for. I wonder if the "AC-E<number>-MC" is useful, but I have no experience in this field, so that part could be very useful but I don't know that. Also, I have a few 'patch' sheets, and their name start with "AF". That would mean that they would not remain together with the original xxdp in a alphabetic list. Furthermore, is the xxdp name (CZRLEB0) not more meaningfull? In that case the file name would become: CZRLEB0-RL01-RLV11-PERF.pdf I'd appreciate any good advice before I start next week. If you can give me (private of course) a URL, I will upload them as I scanned each one of them as .pdf - IF you can use them on bitsavers. - Henk, PA8PDP.

Back to computing topic ... Re: OT: timing belts

by dave04a＠dunfield.com

>- What is the largest computer you've fit into a car? Complete Nova 1200 system (full rack) in an early 80's Honda Civic - basically, the top of the rack (with a 9-track drive) wedged in far enough so that it didn't fall out (good thing it has a strong roof) - the rest stuck out the back and weighed the car down to bottom out on its springs - The front end felt *VERY* light, and it would feel as if the front wheels came up if you accelerated while going over a bump.

Interesting "Rare" APPLE PCI Board on Ebay

by cb＠mythtech.net

>Don't know anything about this, but thought you guys might be interested. >It has a Buy It Now of $15.... I'm not sure how "rare" it really is. One of the major mac "parts" dealers (I forget who, small dog maybe), had a bunch of these for sale not too long ago at $5.00 each. They didn't seem to indicate any limit on the supply. Also, from what I understand, the board isn't too useful as the Mac OS doesn't recognize it, and so won't work with the ports on it. It is probably about a rare as the Apple Set Top Box, it certainly seems to be as functional. :-) -chris <http://www.mythtech.net>

Merry X-mas to everyone; Token Ring Christmas gift

by Arno_1983＠gmx.de

The subject says it all... I'd like to wish everybody in "the hobby" a merry Christmas and, as I won't be online too often until 09.01.05, quite possibly a happy new year as well. Thanks to all who - both regularly or sporadically - populate this list and, friendly and helpful, contribute to the massive amount of knowledge as well as to the unique atmosphere here. Double thanks to the people who maintain the list server, moderate postings and generally "do the work", thus allowing this community to flourish. Last but not least, thanks also to everyone who helped me with the questions and tasks I was personally involved with - the network gear transport, the HP disk drive documentation and everything else I forget right now. Also, somebody has a Christmas Gift for a true Token Ring enthusiast (might even suffice for more of them); I hope he doesn't mind me sending it here - he didn't react to private mail suggesting he might crosspost it here: > From: Porkchop <porkchop(a)nic.com> > Subject: [rescue] For Rescue: Token Ring! > To: rescue(a)sunhelp.org > > My employer moved from Token Ring to Ethernet a few years ago. > Finally, the rooms used to store the old 3,000+ port network will be > needed for something else. > > Its all IBM. We have bridges, 8270s (managed token ring switches), > CAUs (controlled hubs), LAMs (expansion options for the CAUs...25 > extra ports per LAM), a few MAUs (uncontrolled hubs)... the CAUs have > fiber options, the 8270s I think have [fiber] ATM cards and some have > fiber token ring cards. All have copper token ring. This is a mix of > type1, type2, rj-11, and biconic fiber.

Everyone in IT would like to see it go to a > better place than a landfill... > > Mid Hudson Valley, New York...2 hours north of NYC. > -porkchop There already were some "interested reactions" on the rescue list, but of course nobody knows if one of them is gonna work out. If this load is aquired, I might well be interested in some of this stuff; I've got some Token Ring NICs at home and a few more inbound, but neither cabling nor a MAU/CAU yet.

HP9845 printer timing belt

by ard＠p850ug1.demon.co.uk

This talk of timing belts has prompted me to post about the one in the HP9845 internal thermal printer (one of those machines is in many bits on my bench at the moment...), Fortunately I am not looking for a replacement belt -- I say 'fortunately' because I've enver seen anything like it. There are 3 sporckets. One on the stepper motor spindle at the back. One on the platten spindle. One on the feed roller spindle. The first 2 are conventioally driven by teeth on the inside of the belt. The last goes against the outside of the belt and engages with teeth there (of the same pitch as the intenral ones). Of course that means it turns the opposite way. I've never seen a betl with external teeth in anything else (although I have seen a chain drive with sprockets engaging on both sides). I think I mentioned that the printhead in this printer can be taken apart. It consists of a coonventioal PCB to link to the cable harness, 7 ceramic hybrid circuits that contain the printhead drivers (and serial-parallel shift registers), the printhead hybrid iteslf and a load of zebra-strip like connectors to link everything together... -tony

Old Unibus PDP-11 XXDP diagnostics

by wacarder＠usit.net

Does anyone have any info/documentation on the XXDP diagnostics for older PDP-11 systems and peripherals? I'm looking in particular for the 11/40 (11/35), RK05, DZ11, RL02, MM11 core memory, RX01, RL01 diagnostics. I have found some info on Henk's site, but would like to know if anyone has a comprehensive list and hints on how to run these, what the output means, how to answer the prompts, etc. I have created RL02 packs with XXDP 2.5 and XXDP 2.2 and I can boot and run stuff from these packs. It appears that the 11/40 diagnostics are on XXDP 2.2, but not on XXDP 2.5. I have an old 1976 DEC field rep troubleshooting guide that refers to various MAINDECs, which seem to have been the diagnostics prior to XXDP. Is there a list somewhere showing what the XXDP equivalents of the old MAINDECs are? Any help would be appreciated. I want to exercise my 11/40 and attached peripherals and see if any subtle gremlins are lurking anywhere within. Everything appears to be working perfectly with the exception of one of my three RK05 drives that I knew was problematic. Ashley

4416-16 probably 16 sector. if they are 5440 (RL02-looking) probably not that interesting, but if they are 2315 (RK05-looking) the pdp8 guys will want them.

Auction Finds

by tponsford＠theriver.com

A couple of good auction finds at the U of A. tuesday: A DECWriter Correspondent which is a somewhat portable printer/terminal. This one was the model B which doesn't have the acoustic coupler, but has the internal modem and a 9600 baud EIA port. What was great about this find is that it came with the origianl Digital brown canvas traveling case and all the documentation (Operator's manual, reference cards and Programmer's manual) plus a spare ribbon cartridge. It is really, REALLY, clean. with absolutely no wear on the keypads and NO discoloration of the plastic, which make me believe it wasn't used recently, or at all! I was amazed about the ink ribbon, when I did run the print test the text was nice and crisp. Remember this is SE arizona where it is drier than a celebrity at the Sierra Tucson detox clinic. This is a circa 1982 machine too! The other find was a Heathkit H-19 terminal which I promptly sold to another fellow collector. The last was a 10 year old, big, Emerson UPS, model AP115 (1.5 KVA, 1050 watt). It unfortunatly, did not have the batteries, but was in working condition and for $2.50, I couldn't resist. I think it has a 96 volt capcity and looks like it can hold quitea few of the small 12 volt VRLA batteries. It had two heavy duty cables exiting the bottom of the case which leads me to believe it might have had an external battery case. I'm trying to find some documentation, any help would be appreciated.

Stuff for sale, cheap

I am keeping the rack, PDP-11/23, RL02s and some packs, and maybe a VT100, but the rest I don't need.

The paddles are included, but one is missing the knob (the pot shaft is still there). I was told it still works, but did not try it out. Also accepting silly offers for the thing.).

Id'ing disk cartridges

by rigdonj＠cfl.rr.com

Anybody have any suggestions aout how to identify what drive/system these are for? I picked up several 15" removeable disk cartridges earlier this week but I don't know what drive or system they're for. It looks like they came from a GenRad test station so it was probably some kind of DEC based system. A couple of the disks say "Scopus Corporation System 90". Anybody have any idea what that is? One disk was made by Magntic Data and is a model 46. Another was made by Nashua and it's model 4416-16. I just found another marking that says one of the disk is for a GenRad 1796 ssytem. Anybody know anything aboutt the Genrad test stations? I think I have all of the system disks for that system. FWIW the system was used for testing a transponder for the MilStar satellite. Joe

Help: Looking for IBM timing belt replacement.

by dwight.elvey＠amd.com

Hi Grainger claims to be a whole saler. They like to always deal with companies. Even though not incorporated, they have no problem selling to our small water system company ( 7 homes ) but won't sell to me as an individual. If it is taxable, they don't need a tax number. I'd suspect that if you gave them most any fictitious name they would sell to you without question, even in small amounts.

CBBS version 3.5, and other musty stuff

by tomj＠wps.com

OK! I finally used 2, 3 brain cells, worked out the problem with my Centrol Data 64K RAM and got my CP/M machine working fine. (ANother SRAM dies in the Seattle 16K card... a bad sign). Ran a half day's worth of mem tests (good ones) seems OK. Took the bad bearing out of the noisy B: drive (it was a sealed ball bearing ass'y, not a plain like I thought; I washed it out, added some light lube, wrote down the part number, will order one, it's quieter in the mean time). Got the serial port working (simply plugged into the "PC" serial card (PCMCIA) in my linux laptop), default 9600 baud worked as-is! Using minicom on linux. XMODEM protocol failed; not sure what the problem is. Possibly minicom's XMODEM doesn't do checksum xmodem, only crc, my program (telink) doesn't do crc. So I did everything as ASCII. I converted a few diskettes worth, most notably CBBS 3.5, 1980 version. I had a read error on MODEM 2.17' diskette, but a head clean might solve it (the head goops up every 30 minutes... not a good sign). This was just a half-assed first-pass at the job. I really should simply plug the drive into linux and copy them, I'll probably do that, but I want to shake down the system too. http://wps.com/CPM-80/ Just a raw dir for now, it'll grow into a real web page.

I have a stack about the same size, and I've been thinking about scanning stuff like that (to PDFs or 600dpi TIFF), when my department gets its big scanner, probably in January (Sorry, Henk, it's not an Oce). A list of what's available would be good. I suspect that a lot of what I have overlaps with Henk's, but if I can fill in any gaps, I'll try to do so. Some of the diags are quite long, tens of sheets 2-up, double-sided, except for the first few pages, as Henk says, but some are relatively small. > I could start making a list of what's in the box.

Captain Magneto

by cb＠mythtech.net

Anyone here ever played the old Mac game Captain Magneto? Anyone ever win? HOW?!?! I can get the jet pack and I can fly into the castle past the killer spider, but I can't figure out how to put together the rocket. I also can't find the key to open the door on the micro island to get the laser gun. Without the gun, it is next to impossible to kill that bastard spider guarding the castle. If I can't kill him reliably, then I don't think I have a shot at getting the rocket working. I've wanted to beat this game for eons... and every Xmas I think about it as I plan to return to my folks house and memories of sitting playing for hours on end at the 128k Mac come flooding back. So its that time of year again, and I still want to win the damn game! -chris <http://www.mythtech.net>

If you require more storage, go and get a HSD05 and a Storageworks shelf to put it in. eBah has them quite regularly. A Storageworks shelf is a rackmountable SCSI drawer system, holds 8 modules. At least one of those would be a PSU, the rest can be disks or tapes. A HSD05 is a DSSI <-> SCSI converter that appears on the DSSI bus as an attached server with multiple RF7x disks.

parallel keyboards

by dwight.elvey＠amd.com

Hi It seems that every now and then, people need a parallel keyboard. There is an auction on ebay for two keyboards that were designed for a Franklin Ace. I've bought from this fellow in the past and these are good quality keyboards. They are NOS. They require only +5V and are ASCII true out. I have hacked the PROM for this board and can give you the locations to change the key behavior for specific operation that one might need for another machine. They can take a standard 2716 but have some type of 2508 on them. They have a 8035 or 8048 as the processor. If no one else bids on these by tomorrow some time, I'll bid on them. It would be better to see these go to someone that needs them now then to sit in my spares pile. Check ebay #5149974404 Later Dwight

4Kx1 static RAMs...

by tomj＠wps.com

My old machine is slowly becoming sensible. Turns out I had three bad RAM chips in my Seattle 16K boards. They're TI 9044's, I assume are 2147 type. Jameco sells them for $6 each; is there a better source? (They're also 55nS claimed, about 3X faster than what's in there now!) I juggled chips such that the duds are at 9000 - 9fff, so I can boot CP/M (62K system) and run some programs (memtest, sid...). I've got to figure out why the floppy controller won't talk to side 2 (sectors 27 - 52) and I can do that in 16K easily. My B: drive is loud OH MAN IS IT SO LOUD I have to power it off after a program load! Need to find another double sided drive. Out of sheer laziness, to avoid even the faint effort it took to find the bad chips, I yanked all my nice static RAM and swapped in my other RAM cards, one by one: * Central Data 64K * MSC 64K * mumble brand, some acronym, no manual (I'm not at home right now) My EPROM monitor resides at 7800 - 7fff, uses a dozen bytes RAM below 7800. It self-copies into RAM and turns itself off (for a clean address space after boot). Central Data: set the jumpers right, plugged it in, Nothing Happens. (Boring story & expletives deleted) it shorted +16V, popped the fuse. Another one of those !@#$%W^% tantalums; 47uF/35V. Replaced with an electrolytic (it was just down near the card edge). Card works now, but flake-ey results, failed address-contention tests, couldn't boot CP/M. It's all 4116's, lots of jumpers for buss timing, ugh. Needs Work. Reference separate rant on capacitors. MSC: Dislike this thing's RC filters on the data/address lines! Crock-detect! I forget the problem, but had problems with one bank (32K). Mumble: Inert. All the static cards back in, debugged the problem. For the S-100 buss, I'll stick with static memory, thank you!

Another iPDS query

by Innfogra＠aol.com

Joe; Do you have any software that drives or uses the iSBX 251 bubble memory module board? My 1986 Intel Development systems handbook says "The iPDS can be used as a general purpose desktop computer. The widely used CP/M microcomputer operating system is available for the iPDS from Intel. It supports iPDS systems with single or multiple disk drives, and iPDS systems using bubble memory for mass storage." Is this inherent in CP/M from Intel? Has anyone tried this? I think I have Intel CP/M for the iPDS but don't have any bubble memory left. Nor do I have any of the 4 way iSBX boards for the iPDSs left. Paxton Astoria, OR

The iPDS is alive!

by river＠zip.com.au

Hi, Thanks to Dave, who sent me the Teledisk images of CP/M and ISIS, I was able to get my old iPDS running after sitting (and doing nothing) for the past few years. For those interested, I used Teledisk Version 2.11 running on an IBM PS/1 (25Mhz 486) running DOS5. I used 360K DD diskettes in the 5inch (1.2M capable) drive and it worked without any errors. I made a couple of copies and they all booted flawlessly in the iPDS. Wonderful stuff! The iPDS also came with a programming module for the 8748, 8749 and 8751. I'm not real familiar with these chips, but I may have a few around and I think I've got the spec sheets on them, so I'll have a bit of a play I can do with it. The MDS225 restoration is going well. I have contacted the seller who has a box of cables and I'm going to see him later this week to see if the dble density drive array cable is there. I hope so 'cos it saves me having to make one. seeyuzz river
