I've recently come across a Sord IS-11 (I think that was the model number....) with a 64k ram expander, the microcassette drive, and a full set of Eproms. It has all the manuals, but no power supply. Since I haven't heard of one before, and haven't seen on listed on ebay, anyone hear interested? Let me know or it goes in the recycling pile, since I've completely run out of collecting room.

I used to have two of them... if you are talking about the same Zebra systems I had. I don't know much about them. One of my first duties at this company was to replace them with PCs. They were used to run the "PICK" OS, and in that run an interviewing system called "Oscar". As far as the use I saw them doing, they really were nothing more than a terminal server. They were replaced within weeks with 386 PCs with DigiBoards, and an intel build of PICK and Oscar. IIRC, the Zebra's were based around a Motorola 68000 processor (I think at 16mhz, not sure... this is totally off memory). I do have 2 fairly large manuals for them still (3" binders with an assortment of smaller manuals or "chapters" clipped in them). I might also have a tape backup drive for it, but I think they had tape drives built in, so the external drive I am thinking of may go to my AT&T unix machines. I think I also still have the modem that was used on the Zebras (although, I would guess it is probably nothing more than an fairly standard 300 or 1200 baud modem). -chris <http://www.mythtech.net>

Creating PDF's from scanned image files

by hansp＠aconit.org

I think I have cracked the issue of converting scanned images into PDF using only freeware! First off get the imagemagick toolset from www.imagemagick.org You will also need c42pdf available at http://c42pdf.ffii.org/ c42pdf will create pdf files from group 4 encoded tiff images (only). To get to those images use imagemagick convert : convert -compress group4 <any image file> image.tif c42pdf image.tif will create image.pdf. Read the docs to see how to build multi page PDFs. This has worked for a bunch of files for me so far. -- hbp

H744 regulator whistle

by pete＠dunnington.u-net.com

I have two H744 regulators in my PDP-11/40, along with an H7441, H745, and H754. I also have two spare H744s and one each H745 and H754. All the H744s emit a fairly loud whistle, and it's driving me nuts. I've seen a note somewhere that a loud whistle is caused by the coil de-laminating, but I don't think that's the case. I tried swapping the two original H744s for spares, no difference. I also tried swapping the coil from the spare H745, which runs almost silently, and that made no difference either. I don't think I can just remove (short out) the coil either, as this is a switching regulator and the coil is needed to make it work properly. Any suggestions? -- Pete Peter Turnbull Network Manager University of York

Does anyone have details about the STC ZEBRA? Tony?

by dpeschel＠eskimo.com

STC = Stantec = Standard Telephone and Cable. They sold a truly strange computer called the ZEBRA. It was designed to be cheap (it used a drum for storage and did arithmetic serially). The instruction format is unusual -- 15 function bits (I think each affects a gate) and a 12-bit address of a drum location and a 5-bit address of a "fast store" location (basically a small number of registers). The amount of logic in the machine is small, so the instruction decoding is simple in a sense. But the logic is connected in very subtle ways -- two things can happen independently, or an instruction can set a whole sequence of events in motion. There is an emulator for this machine; I have some of the literature about it too. But I don't have the manual or the schematics, and the literature I have just doesn't make the design "click" into place in my head. The emulator code is not very intuitive either. So that's why I'm hoping someone else has heard of this machine. -- Derek P.S. Tony, I think you would enjoy this design (if you don't already know about it).

OT: DELL SUCKS! Re: PC Gamer, best 50 classic games issue?

by mythtech＠Mac.com

>But if you pick the cheapest, you may find they underestimated >what it took to run a profitable company that will survive, and >6 months later are out of business. > >I've seen it. People that bought from cheap local vendors that >offered 5 year, even lifetime, warranties, gone, gone, gone. > >They come and go like sand on the beach. > >If they want a cheap PC, they have probably doomed themselves >to failure from the outset. I agree, but still, my attitude has become (due to years of dealing with windows and the declining quality of PC hardware), that you can spend $3000 on a PC, or you can spend $300 on a PC, and they are both going to work (quality/stability wise) about the same. Either way, you will wind up with problems keeping windows running. Granted 99% of this is due to windows sucking so bad (if you aren't planning on running windows, then this is a totally different situation, but I am only dealing with advise I give to prospective Wintel buyers). As for if a company will be here in 5 years to support the PC, there are no bets that ANY computer company that is here today will still be here 5 years from now. (perfect example of this. A few years ago, my fire department decided to switch from a Mac to a PC since we need to upgrade the computer anyway. The PC people argued that Apple wouldn't be here in 5 years, so don't get a Mac. Us Mac people pointed out that it doesn't matter, because in 5 years the computer will be ready to upgrade anyway. Well, the vote went to get a PC... and to buy a Packard Bell. Well... Apple is still selling Macs... and Packard Bell... well... they are the ones that are gone... so the computer was replaced AGAIN, this time with a Gateway... who now looks to be dying) But I would still support people going to a fly by night, and risk them going under. I don't advise getting long term support contracts anymore, simply because I am so unimpressed with the support you can get. Phone support tends to be luck of the draw. 90% of the time you get a brainless bonehead. On site tends to be just as bad (I might be in one of those "bad contract support" areas for the local "on site" support options... don't know). So why pay 5 times the price to get a "brand name", when it is going to give you the same headaches as the cheaper CompUSA sold, or mom & pop sold PC. At least if you buy from a local vendor (CompUSA, or a mom&pop), you can carry the computer in to them and bitch to a person... you aren't stuck with phone support. And buy going with a cheap mom&pop... you are more likely to get them to fix it. CompUSA will tell you to contact the computer maker. Although, I do hear good things about the local Gateway Country store in doing on the fly repairs on a carry in. But honestly, I just don't recommend Wintel machines AT ALL anymore. I really tell people to look around and find another option. If you want if for games get a console system, if you want it for internet access, get a used PC (I recommend used Win systems over used Macs for an internet only machine, simply because, like it or not, many web sites cater to windows and IE... that and many of the people that ask me about an internet only machine want AOL, and the windows AOL client is much better than the Mac one), and if you want it for general computing, get a Macintosh. Windows blows, and is no longer worth the money and heartache for new machines unless you NEED it for some reason. But that is just my opinion. -chris <http://www.mythtech.net>

Ugly Computers (Was: RE: Appropritate comic strip....)

They're happy to oblige, so I'll get a chance to see how durably >the critter is constructed. It does seem like it'd be likely to get >broken. I don't think it will be any more prone to breakage than any other LCD display. The base should be just as durable as any other computer, and the swing arm should be no less fragile than the thousands of lamps that have a similar arm on them. If anything, I would think it is MORE durable than many computers, being that apple has done a good job making very durable iBooks. BUT... like all LCD display's, that portion will be prone to cracking if abused. That shouldn't be much of a problem for the standard home user, but for the K-12 market... I have never thought an LCD display (of any kind, from any maker) was a smart idea. Good old heavy glass CRTs take a much better licking than LCD could ever hope to (in testing, it took me a number of swings with the base of a rolling chair to break thru the glass of a VGA monitor, but my laptop LCD cracked with only mild weight placed on it when I stepped on it) In the long run, it is probably unlikely that too many people from this list will "get it" with the new iMac. The reason being is, the new design is going after the market of people that want a computer to fit around their life style. So they are trying to go after the "its furniture" market. The nature of most of the people on THIS list are ones that like a computer to BE a computer... a nice traditional, boxy, blinking light, noisy COMPUTER. Apple has been moving farther and farther away from that kind of market. This list is full of people who's life works around the computer, and apple wants the market where the computer works around life. I mean really, the target market for the new iMac is certainly not a group of people that tend to rent storage garages just to store their extra PDPs (You aren't going to get a new iMac user group where the people discuss staying warm in their storage shed by sitting on top of a mini while writing code on an old portable and its 5" screen!) -chris <http://www.mythtech.net>

When the CPU is running a program, it only uses 16-bit addresses in the program.

It automagically works, except for a very few cases (and I can't even think of an example at the moment). The reason is that most I/O devices actually decode a signal called BBS7 (Bus Bank Select 7) instead of the highest address bits. The signal gets its name from the fact that the original LSI-11 used 16-bit addressing, and bank 7 was the I/O page. It's still only activated for I/O page access, regardless of whether your processor uses 16- 18- or 22-bit addressing. -- Pete Peter Turnbull Network Manager University of York

(what I want to do to it) Well, first we had MacOS X, the revamp of NeXTstep. Then we had the G4 Cube, an obvious though modernized callback to the NeXT Cube design. Now it's like they've tried to create something that's entirely non-NeXT, at least asthetically. Basing the design on a white sphere places it completely opposite the black cube of the NeXT. So I'd call it the notaNeXTintosh, or maybe the anti-NeXT. I think it's a moderately ugly design, but I asked my employer to get me one as I'm curious (though I'm not curious enough to get one for home). They're happy to oblige, so I'll get a chance to see how durably the critter is constructed. It does seem like it'd be likely to get broken. -brian.

What exactly is a MINC-11, and does anyone need one?

Hello all, Another item I keep forgetting about is a digital MINC-11. This appears to be a data acquisition system of some sort. The MINC chassis contains only a clock card and an AD card. The chassis is on a cart that also contains a digital RX02 dual 8" floppy drive enclosure. The most curious thing is that there is a label stuck to the front warning that the unit "220VAC/50Hz only". I don't know if this is the only voltage it will run at, or if it is simply set for this voltage. I don't believe we ever used this equipment. I think we acquired it when we purchased some other surplus equipment back in the 1980s. Can anyone use this thing?

VAX 6000-460 booting saga continues ...

by gunther＠aurora.regenstrief.org

Hi, after a quick excursion in getting a PDP8/A up and running (as far as that gets without any peripherals other than the programmers console :-), I'm now back to the big toy. The 6460 is still waiting to boot Ultrix. Recap: it's up and running from VMS 7.2 or VMX 5.6 from RA90 disks through KDB50 and KDM70. I don't have any working IP communication because the VMS 5.6 just doesn't have anything and 7.2 has MULTINET which just refuses to run with the old license key, nor with a cheat hack, nor with a hobbyist license key. So I'm now down to transferring files through modemspeed. (I could write a TK70 or 9-track tape at my workplace, but that's a hassle by itself, so I keep that as a last restort.) Luckily I have kermit on the VMS 7.2 so I have a convenient yet slow way of transferring files. I also have a boot tape from Isildur. That's Ultrix 4.1. That version seems to not support the 6400, it boots up until a certain point and then simply halts. I'm very sure it is *not* a tape read error and that the boot process fails somewhere after the VMB is loaded and probably at the point where vmunix is started. I assume it just can't get a hold of the console at that time to put out an error message and just dies. Even the primary ultrixload will dump an error message before it halts. The more recent developments: I also have an Ultrix-4.5 CD. But no CD ROM hooked to the VAX and no other VAX (InfoServer) with CD ROM and so I cannot boot that. I could possibly just write the CD ROM image onto a disk verbatim and fingers crossed boot from it. However, I cannot pump the 178 MB through the 9600 b/s line, or else I have to have that thing up for 2 days and two nights only for something that might just plain not work. Interestingly this CD is not an ISO file system but a simple UFS written to the CD in 10 kB blocks. FreeBSD's mount unfortunately cannot mount that. However, I just dd'ed an image onto disk and vnconfig - mount form there. It's read-only and disklabel doesn't make any sense out of it, but I can read everything just fine. Today's news: So, I decided I make myself a bootable tape from the reverse engineered Ultrix 4.1 boot tape and the new 4.5 files from the CD. The Ultrix boot tape comes with a vmunix that apparently has some sort of standalone memory root file system. Then it supposedly is able to set up a disk and install a dump backup onto that disk. That dump backup contains mkfs, disklabel, ifconfig, rcp, uncompress, and tar, so I have everything to set myself up even if the autoinstaller cannot deal with my hack. The boot tape I could read from VMS. $ MOUNT/FOREIGN/BLOCKSIZE=512/RECORD=512 MUC6 $ COPY MUC6: FILE.00 $ COPY MUC6: FILE.01 $ COPY MUC6: FILE.02 --> ERROR $ DISMOUNT MUC6: $ MOUNT/FOREIGN/BLOCK=10240/RECORD=10240 MUC6 $ SET MAGTAPE /SKIP=FILE:2 $ COPY MUC6: FILE.02 $ COPY MUC6: FILE.03 $ COPY MUC6: FILE.04 $ COPY MUC6: FILE.05 ... and so on. It's got some 40 or so files on it. What there files are we are being told from the ultrixload.c source code. FILE.00 is the ultrixload image, about 18 kB in size. Ultrixload is said to load either vmb.exe or a standalone kernel from a non-file structured device. The layout of the boot device is descibed as: FILE.00 - ultrixload FILE.01 - a combo consisting of - descriptor block 1 512 byte block - vmb.exe (optional) - vmunix (compressed if not a TK50) This magic descriptor block is described as: struct desc { union { char pad[512]; struct { struct exec x; /* a.out image header */ int nblks; /* num of 512 byte blocks on medium */ int vmbblks; /* size of VMB in 512 byte blocks */ int compressed; /* 1 = compressed, 0 = not compressed */ } d } un }; By loading the initial portions of the other files down to my BSD system and using file and stuff, I figured the other files: FILE.02 - the ROOT file system dump FILE.03 - an uncompressed tar of the instctl files (on the CD) FILE.04 - a compressed tar that is called ULTBASE450 on the CD FILE.05 - a compressed tar that is called ULTBIN450 on the CD ... and so on. The instctl tar begins with a file called ULT.image and that is just a list of files beginning with ROOT, ULTBASE, ULTBIN, that apparently correspond with the files on the tape in that order. So, my plan is to fiddle with files 0 and 1 only and keep the rest, as it should be compatible with the 4.5 kernel. That reduces the amount of data to transfer tremendously. Quickly I found that I have no ultrixload on the CD, so the old version will have to do. As I have strong indication that that works, I can leave it at that. Remains to work on file 1, that funny combo of descriptor, vmb.exe and vmunix. The tar file 4 (ULTBASE) contains a vmb.exe as well and so I could compare the two files that came with ultrix 4.1 and 4.5 respectively. They were both the same size and actually both the same. I successfully extracted another exact copy of vmb.exe using dd if=file.01 bs=512 of=vmb.exe skip=1 count=86 So, whatever VMB.EXE is for (sounds like a VMS boot block), I can reuse the old one. Given that I have a standalone vmunix, all I'd need to do is cut and paste that somewhere after block 86 to the end of file 1 with a few cat and dd operations. But here the problem starts. I cannot interpret the descriptor block very well. It tells me that the VMB.EXE is 86 blocks in size and that is exactly 44032 bytes, that corresponds with the actual size of the vmb.exe file from the tar archives. Good, but apparently the vmunix is not a complete piece. Apparently that descriptor block's a.out header slot actually holds the a.out header from the vmunix file and the vmunix file is right after the vmb.exe without it's a.out header. I also see a lot of 0 data in that region. So apparently I will have to fiddle with that a.out header and need to know just where to cut vmunix. That is a problem. I will try to figure that out somehow. My hunch is that the a.out block (which I haven't been fiddling with since I ported Kyoto Common Lisp to 386/BSD 0.1) allows for the executable to actually have some other stuff like that vmb.exe before the actual start of the executable image. I have no idea though what the purpose of this stupid vmb.exe is. All in all I'm optimistic. I'd love to make a boot tape with 4.5 Ultrix that I could then share with my friends (that is you) who also want to get their 6400s converted to Unix. As always I'd be thankful for any helpful ideas you might have. regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

DPC Interface Inquiry

by tarsi＠binhost.com

Got a good one, folks. A friend of mine is trying to use a Spur U.S.A.-1/DPC(7U) box. Spur U.S.A being the model and DPC being sub-model. I guess he knows that U.S.A. stands for Universal Subsystem Adaptor and DPC stands for Data Products C????. It takes input from a 50-pin amp connector and outputs to an IBM Channel Bus & Tag. He knows what the box does and has a Bus & Tag box to use it with, but can't figure out what DPC is or where to find the 50-pin amp connector or the pinouts for it. Anyone help out? Thanks!

I had posted disbelief about this in alt.sys.pdp10... I'd not heard of eMag, but if eMag is EMTEC Magnetics GmbH, then that's BASF! They didn't quite invent magnetic tape, but they claim to have been the first to have commercial success with it. If BASF is abandoning 9-track magtape, then I fear it's true, the end is near...

Reading PET tapes (was Re: Apple disk -> MSDOS)

by mhstein＠usa.net

Some questions for the CBM experts: CBM->PC seems pretty trivial through a Parallel or Serial adapter (although ML might be tricky 'cause you can't just list it), but how do you get it back to a CBM? If you're just archiving, couldn't you just connect the CBM cassette port to the PC sound card line in&out, with _maybe_ a little padding and/or shaping since I think CBM, unlike most folks of that era, squared up the audio a little in the datasette (although ISTR that it usually worked OK with a normal recorder, and presumably you could set the levels with the PC volume controls)? Especially if there's an app that can decode the .wav files, what else do ya need? Reminds me of the days when I "networked" my PETs with a 40' cassette "Null modem" cable. Where could I find that cassette reader & .wav decoder, BTW? Tell us more! F'rinstance, I see someone elsewhere on the list looking for Phuzzy-Wuzzy; I remember it well and probably have it somewhere (although I didn't find it either in the Cursor tape index). So, if I do find it and this person wants it, how, specifically, could I email it to him/her in a format that he/she could load into the PET without having to build anything complicated (or mailing the actual tape)? Seems to me this goes on all the time in the amazingly active CBM community, I'm just not sure of the exact details (cable pinouts, required software, etc.) BTW, need a chiclet keyboard? Just recently tossed my small KB 2001 (yes, working - I can hear the curses...) but I think I've got at least two almost new chiclet keyboards (no worn-off legends, protective plastic still on most keys) left >from the days when we were replacing them with the full-size ones (that's me, toss the good stuff & keep the junk). Mind you, you might have to take the case with it, along with the funky chopped-up datasette. Also have a 2001 motherboard, maybe 2. BTW, speaking of CBM, I recall a recent discussion abt using a US 8032 in the UK and problems with a wavy screen (not to mention learning a lot about magnetic shielding); I wasn't positive at the time, but from what I've read there definitely (as definite as the printed word gets) was a different ROM for 50Hz operation to avoid that problem. mike ---------------------Original Message----------------------- From: Ethan Dicks <erd_6502(a)yahoo.com> Subject: Reading PET tapes (was Re: Apple disk -> MSDOS) - --- Sellam Ismail <foo(a)siconic.com> wrote: > On Wed, 9 Jan 2002, Ethan Dicks wrote: > > > My X1541 cable also has a 6-pin C= cassette port on it.

Not audio (though there is an app that will decode .WAV files of PET tapes). Someone wrote a DOS app that reads the parallel port bits and converts them into a .T64 file directly. For alignment/phase, there's a graphical mode that scrolls the data up the screen along with "guard bands" that show where the app thinks a 0 and a 1 are. You use the cursor keys to align the data from the tape drive and the guard bands for optimal data parsing. Once you have an offset >from this process, you can use it as a command-line parameter for bulk reading. It works well enough, but I really wish the source were available (it never seems to be for DOS programs, unlike Unix and Amiga software). I have a small pile of PET Rabbit-format tapes that I want to extract from. My BASIC 2.0 PET needs repair (keyboard problems), so I can't just read the data and save it to disk. I have plenty of 8032s, but only one 2001 (got the 80-col PETs from university surplus for $10 a few years ago; we got the 40-col, 32K PET when I was grade-school for $1175). - -ethan

3com 3station

by jeff.kaneko＠juno.com

The 3Station was an early IBM compatible diskless workstation. They used a 12Mhz 80286 IIRC. The network boot protocol was proprietary to 3COM, but once you were linked to a disk image on a Server running 3+Share (and 3+Start) you could use any protocol that had drivers for the NIC on the 3Station. There were two version of the 3Station; the main differences being Video and maximum memory size. It seems like there were ROM's available that allowed you to use it on a Novell network, but I don't remember the details. I don't think using it as an X-Station is a good idea-- I strongly suspect you'll need a bit more muscle to do X. Besides, if it's the earlier model 3c1100 (very likely) it can only do EGA, MDA or (yeek) CGA. I still have a copy of 3+Share (and 3+Start) around here someplace . . . That remark about the 3Server needing constant attention was right on the mark. I lost quite a few nights sleep maintaining one of these beasties (my first SYSADMIN job). I could almost run the diags in my sleep after awhile. The backup system almost never worked.
