PDP-11/34c website?

by GOOI＠oce.nl

Hi Jonathan. Check out http://archives.decdocs.org Click the link "print set archive" There you find, among others, the Print Set of the 11/34. The folder "manuals", down the list, contains all you need. KD11, FP11, KK11, M9312, etc. Especially look at the KK11 manual. It describes the step you must do to install the cache next to the FP taking into account the power distribution. It works, I did this at home with my 11/34A. BTW you need a special "over the top" connector to connect one CPU board + cache + FP board .... Sorry, I do not have a spare one. Does an 11/34A with FP and cache become a "PDP-11/34C" ? Good luck with the conversion, - Henk. > -----Original Message----- > From: Jonathan Engdahl [mailto:jrengdahl@safeaccess.com] > Sent: vrijdag 12 april 2002 4:20 > To: classiccmp(a)classiccmp.org > Subject: PDP-11/34c website? > > > Is there a website somewhere that will tell me exactly how to > put the boards in an 11/34c?

Any interest in ROM 00 Apple IIgs?

by r_beaudry＠hotmail.com

Hello all, I have in my posession, three tested, working, Rom 00 Apple IIgs machines, complete with monitor, 3.5" and 5.25" floppies, keyboards, and mice. I am wondering if anyone would like them, for a nominal price + shipping. Before anyone misunderstands me, I am not asking for tons of money for these beasts, as I realize they're pretty crippled (They had defective video chips, and the ROM version doesn't allow you to run GS/OS). They do run most Apple IIe sowftware, and could be considered as an accelerated IIe. Not the best example of a IIgs, however, if you are looking for a machine to complete your collection, they are available. Note that NONE of them are the "Woz" variant. I got these (along with several "ROM 01" and "Rom 00 upgraded to Rom 01" IIgs machines) from a local school. I would like to save them from the dump, and help the school out as well. Therefore, I will take offers on these machines until Thursday 04/11, 11:59PM Eastern US time. ANY AND ALL proceeds will be donated back to the school the computers came from. I will separately notify the highest bidders that they have won.... Your chance to own a small part of Apple II history, and help out a local school as well.. I will ship anywhere, worldwide, that the US Postal Service allows me to ship, and I will consider shipping just a CPU (i.e., no monitor, or no drives, or whatever combination you want), as it will cut down on shipping... The units will be shipped from US ZIP code 01473, and to give you an idea, a monitor weighs about 25 lbs boxed, and a CPU weighs (I think) 8 lbs. boxed... I will quote actual weights and shipping charges to anyone who asks.... Thanks!

Amiga 2500 questions

by doc＠mdrconsult.com

Hi. I'm looking at an Amiga 2500, with a 5M hard drive, unknown ram, a lot of boards in it (the owner knows as little about it as I do), and no keyboard, mouse, or display. He wants $30 for it. He has a display >from a Commodore Colt hooked up to the composite video port, and the 2500 will boot to a screen with hand holding a WorkBench 1.3 floppy shown. Are keyboards as hard to find as it seems? That's the showstopper so far. Is $30 reasonable for a partially tested A2500? Will the kbd/mouse from the Colt work? Aquiring minds want to know. :) Doc

> -----Original Message----- > From: Douglas H. Quebbeman [mailto:dquebbeman@acm.org] > To capture an existing CD-ROM into an image file, most > likely, Chris is correct, but I haven't gone that direction > yet. I have. It works as long as the block size isn't odd. Generally any cd will take a block size of 2048 bytes, however, if the CD is "bad" (scratched, or what not), a smaller block size (1 ;) may help you get more good data at the expense of some speed. You can also use the conv=noerror option to ignore read errors if you really want whatever data you can get. As somebody else mentioned, cat works too, but it doesn't have an option to make it ignore read errors and keep going. Otherwise, you're right, use mkisofs, or mkhybrid to make a filesystem from some of your files, and then use cdrecord to burn it. There is another program (cdwrite?), but I don't think it has nearly the same level of device compatibility, not to mention that the number of systems cdrecord will build for is very impressive.

Semi-OT: Power supplies

by pat＠cart-server.purdueriots.com

I am looking for some sort of service manual or something on two Power supplies I picked up yesterday at Purdue Salvage. The first one is a HP 711A 'adjustable AC/DC power supply', which is fairly old and tube-based. After plugging it in, nothing happens - no filaments light up, etc. I haven't had time to go through and 'probe' it to see if the transformer is still OK yet, that's my next step. If anyone has any info on it, please drop me a line. BTW I've checked the fuse. The second one is fairly new - a HC Power Model HC10-1A switching 5V, 200A power supply. I think it was manufactured in 1992, making it 'just classic' as far as electronics go. I've taken it apart, and the line-side smoother caps are charging up, so I'm guessing a control problem. I'm going to try and contact Power-One (they aparently bought out HC Power) tomorrow to try and get info on it. I would really like to get this working so that I could try and use it for my new SSI/MSI (perhaps a few PALs if necessary) minicomputer I'm designing. [Aside: If they'd only give me some sort of course credit towards my BSCompE for doing this, I'd be really happy.] -- Pat

Gould 9540 PSU

by red＠bears.org

I've recently inherited a Gould 9540 (8 MHz MC68000 CPU, Multibus) which would appear to run some sort of UNIX variant (System III, if I had to guess) I'd like to check it out, but the system sports a rather large sticker on the back panel which states it was wired at the factory to run on 240V. Before I spend a lot of energy trying to figure out whether it's still true and how to strap it for 120V operation, I thought I'd ask if anybody knows how to tell, off the top of his or her head. ok r.

OT: BLAME WHO????????? (Warning: Possible Humor)

by rigdonj＠cfl.rr.com

BLAME WHO????????? Let's see if I understand how the world works lately... If a man cuts his finger off while slicing salami at work, he blames the restaurant. If you smoke three packs a day for 40 years and die of lung cancer, your family blames the tobacco company. If your neighbor crashes into a tree while driving home drunk, he blames the bartender. If your grandchildren are brats without manners, you blame television. If your friend is shot by a deranged madman, you blame the gun manufacturer. And if a crazed person breaks into the cockpit and tries to kill the pilot at 35,000 feet, and the passengers kill him instead, the mother of the deceased blames the airline. I must have lived too long to understand the world as it is anymore. So, if I die while my butt is parked in front of this computer, I want you to blame Microsoft and Bill Gates ...okay?

NEC Multispeed boot error... what now?

I am hoping you can send me in the right direction for restoring this very old laptop that my father gave me. It is posting a message that reads as follows: Fixed disk setup (1701) incomplete. Trying to boot from A drive: Warning!! Fixed Disk Controller is bad or Low Power, Can not boot up from fixed disk, insert system disk drive A or B... Press any key when ready.... What precisely do I need to look for when getting a system disk for this computer? It didn't have anything in the original bag it came with. The screen reads as follows when I turn on the computer: Phoenix ROM BIOS Version 2.51 Copyright (c) 1984,1985,1986 Phoenix Technologies, Inc. NEC Multispeed Please offer any guidance you may have!

Questions regarding Tom Shoppa.

by Antonio.Carlini＠riverstonenet.com

>Why is 212992 magic? OK. I'm an idiot :-) RT-11 has a limit on disk size, and my (poor) recollection is that this might be in the region of 64K blocks (512 byte block ... i.e. 16MB per disk). This would be 16384 2048-byte sectors. 13*16384=212992. So my guess is that when you use this RT-11 CD on an RT-11 system, you tell it to map partition 13 (and 14 etc. onwards to the end). In which case writing an image would be a breeze. Create your ISO file system as a binary (ISO9660) image file and overlay onto an image of a full 650MB or 700MB CD. Create images of however many RT-11 "disks" you think you can fit onto the end. Determine where the next 16384 2048-byte boundary is and drop your first RT-11 partition there, then keep overlaying further partitions until the end. OK. I don't know how to do this on Windows 98 with the available tools, so you'll either have to do it on Unix (or OpenVMS) or knock up a quick tool in C for Windows. Or you could ask Tim how he did it (but I bet W98 was *not* part of the answer!). Antonio

Of course, I want to be able >to do this under Windows 98!! Does anyone know if that is >even possible, let alone how it could be done? I don't know the specifics of RT-11s requirements for the CD. I expect that RT-11 sees it as though it were a hard disk of exactly that many blocks (well 4 times the number of CD blocks because of the 2048<->512 byte thing). Many (many) years ago when I used an LSI-11/23 under RT-11, we had a 40MB drive that emulated 4 RL02 drives (or some such). I don't recall if this was done in software or hardware - quite possibly it was a software driver that came with the disk. Why is 212992 magic? What do you do to make this CD visible as 7 (or whatever) disks under RT-11? Essentially your CD is a stream of N 2048 blocks and is presumably seen by RT-11 as such (at a sufficiently low level) and then given meaning by some software layer. A typical method for generating a layout with both ISO and "other stuff" in logically separate areas of the CD would be to start by generating a binary ISO-format file with just the ISO data in. The first 64 2048-byte blocks (or is it 32?) are ignored by the ISO9660 standard - they are deliberately not used. Now create an empty image file, the size of your CD. Overlay the ISO image file onto this. Now you slip the PDP-11 boot block in there and add whatever else you need at the end in whatever format you want. The ISO file structure will be unaffected (so long as you tack things on after its logical end). What you need to find out is RT-11s requirements in this area. Actually doing this under W98 may not be that easy. Typically, when I've done CDs that have both ISO9660 and ODS-2 on them, I've generated the image on OpenVMS and burned the image to CD using a PC.

Well, assuming you really mean DA15 (not DB15 :-)) then, yes, all you need is a transceiver. The miniature type that fits straight onto the AUI connector is best, and usually cheap and easy to find.

>Does anyone else have copies of the RSX-11 set of 2 CDs? At one point the RSX, TOPS and RT11 CDs were all available as binary images. I know I downloaded all of them and burned them to CD with no problems. (Well, maybe a slight issue with the RT11 one IIRC - I used W98 and whatever burning software I used was not too happy verifying it ... seemed usable though). Tim does not seem to have any problems with people downloading large amounts of data so rather than ask for a CD, just burn one. Antonio

You are probably thinking of "ex". But "ed" is a proper subset of "ex". The classic answer to the question "point me to a guide" is $ man ed executed on any Unix or Unix-like system. If you don't have one of those running, you can try, with your favorite web browser, a Google search with the key words: unix man ed carl

Boot to non-timesharing then use ED (sorry no other choice usually) to edit passwd file. set the Root user password to NULL (no characters). boot to timeshare level and then log in as root with no password. My ultrix manuals are burried or I'd give more detail. Allison

Info on Bill Godbout

by bobbeleh＠earthlink.net

Hi I'm new to this forum and I'm looking for info on contacting Bill Godbout. I worked for him and Mike Quinn back in the early/mid 70s, testing ICs in the back room of Quinn's. Any help would be appreciated. Thanks, Bobbe bobbeleh(a)earthlink.net ********************************************************************** We do not see things as they are, we see them as we are. **********************************************************************

Anyone Care About RT-11

by IVIE＠cc.usu.edu

> Even if you don't have any bugs to contribute, please comment > if you think a central location is a good idea so that everyone > who uses RT-11 can be aware of the current list of bugs. FWIW, I think a central bug listing is a good idea. Caveat on my opinion: I do not currently have any PDP-11s operational, although I have several that could, conceivably, be put into working condition on short order. I.e., I'm not currently running RT-11, although it's on my List of Things to Do. Roger Ivie ivie(a)cc.usu.edu

Very Old Texas Instruments IC's

by rigdonj＠cfl.rr.com

I found a TI data book dated 1971 and it doesn't even mention 12xx ICs. It appears that by 1971 TI had switched entirely to the 54/74xx series. I have a couple of even older TI books if I can find them. Joe > >Rick, > > SOMEWHERE I have an old TI IC catalog from around that time period.

Getting Unix to run on a PDP-11/34

by hans＠Huebner.ORG

Hi, this weekend, we have been unsuccessful trying to get one of the ancient Unix versions (V6 or V7) to run on a PDP-11/34. The plan is to have an ancient PDP-11 on the VCFe in Munich running a proper version of Unix. THe machine has two RK05 drives, RX01 floppy and a TS03 tape drive. Our first problem is that we have been unable to find or make up a TS03 bootstrap. We considered using RT-11 to transfer disk images to RK05 drives, but we could not figure out how to get the image straight to the disk without having to store it in an intermediate file and writing a RT-11 program to access the disk sector-by-sector. We have a lot of hardware at our disposal, so we took a Emulex TC12 Pertec tape controller from a 11/44 (the 11/44 would also be nice as demonstration CPU, but it has a SMD disk controller for which we have no drives). Not having any documentation on the TC12 we just put it into the 11/34, but it did not work (bus error LED lit). So we're kind of stuck. Any ideas, hints or pointers (especially to a TC12 print set) would be greatly appreciated. Thanks, Hans -- finger hans(a)huebner.org for details

TTL computing

by Lee.Davison＠merlincommunications.com

The point is, I can't see a real difference between a ROM chip and a decoder + gates. Electronically they're much the same thing. Physically, to change the program, I have to use a soldering iron. It is _not_ clear to me why one is called firmware and the other called hardware. How about .. Hardware is the physical part(s) of a design that can be seen, touched, crushed, thrown, weighed etc. Firmware is the idea statically implemented in that hardware.

HP 88780 / 7980XC Interface Question

by fmc＠reanimators.org

"Douglas H. Quebbeman" <dquebbeman(a)acm.org> wrote: > I see lots of references to these drives... > > Do they possess multiple interfaces, or do you get > one that has the interface you need? You get one that has the interface you need, but I think you can swap interfaces; e.g. I've swapped a single-ended SCSI interface board into one that I got with a differential SCSI interface. Note that the interface board is screwed to the back plate which has the cutout for the connector, so if you get a different interface board you may also want to get the appropriate back plate for it. > I've seen one with an HP-GPIB interface connector > on the back, and was wondering if I pull that rear > cover off, will I find a set of Pertect interface > connectors hiding there? Or is that simply a different > model? I haven't looked inside one with a Pertec interface, but the SCSI interfaces expect to plug into a flat cable that is in the base of the drive and I expect the Pertec interface would too. There's also a four-slot card cage in the right side of the drive, accessible by removing a top cover. The boards installed in this cage make a difference too. Later drives have only three cards installed (the read/write/PLL boards and formatter board were replaced by a single board). 7980A and 7980XC are HP-IB-interface drives sold into the HP minicomputer markets. The XC suffix means the drive was sold with a variant board that supports data compression (meaning you can write tapes that are only readable by other 7980XCs). 7980S is the same drive with a SCSI (single-ended I think) interface, sold into the HP minicomputer market. At one point HP offered a field upgrade kit to change your HP-IB drive to a SCSI drive. There is also a variant board that supports 800 BPI (in addition to 1600 and 6250). I believe that 800 BPI and XC compression are mutually exclusive (you can't have one drive that does both). 7979A is an HP-IB-interface flavor of the drive that supports neither 6250 BPI nor data compression. I'm not sure but this may simply be a different-variant board as well. 88780 are drives sold outside the HP minicomputer markets, including OEMs like IBM, Sun, and Tandem. Of course the OEMs came up with their own model numbers. I have some notes that say data compression was option 400 and 800 BPI was option 800, but I'm not sure whether this applied to a 7980 or 88780. -Frank McConnell

I've used it under Solaris. That depends on what he meant by "make ISO images of cd roms." I read that to mean "I want to make a raw copy of the disk, and I'm just saying ISO out of habit." You obviously read it to mean "I want to make an ISO image out of some files I've got so that I can burn it onto a CD." So which was it?

No; assuming you've got files on a Linux filesystem, you use mkisofs to create the ISO9660 image file (with Rockbridge extensions). Then you use cdrecord to burn the image onto the CD. To capture an existing CD-ROM into an image file, most likely, Chris is correct, but I haven't gone that direction yet. -dq -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

should I take RM03's ?

by GOOI＠oce.nl

Hi all. I need some advise. In 3 weeks time Edward and I drive to Italy (some 1100 km) to pick up several PDP-11/70 parts. I have the oppertunity to drag 2 RM03 massbus drives and some packs back home. Now I know already that these drives weigh about 200 kilo, have a disk capacity of 67 Mb and are really power-hungry: at 240 V/50 Hz. stand-by is 3.5 A. running they consume 11.5 A. and rush-in current is 22 A. My experience is that DEC tend to give high numbers for the power consumption, but do these drives eat that much current? Are they worth preserving? Or should I leave them where they are? Next to the 11/70 is looks great (IMHO) but I would love to hear some opinions from other collectors. - Henk.

HP 88780 / 7980XC Interface Question

by dquebbeman＠acm.org

I see lots of references to these drives... Do they possess multiple interfaces, or do you get one that has the interface you need? I've seen one with an HP-GPIB interface connector on the back, and was wondering if I pull that rear cover off, will I find a set of Pertect interface connectors hiding there? Or is that simply a different model?
