What a find!! Snap it up right now! Sounds like an 1186 to me, since the company is an AI company. In their attempt to remarket the Star Xerox redesigned the 8010 hardware and came up with the "Dove", which was marketed as the 6085 "Documenter" or the 1186 "Artificial Intelligence Workstation". I think the only difference in the hardware was the 1186's processor board had a floating-point unit - other than that they were identical machines differing only in the microcode and software. The 6085 ran the "ViewPoint" system, originally know as "Star" and later renamed "GlobalView" :-) You don't have any access to the guts of the machine from ViewPoint, it's a closed system that's specifically designed to write documents, send email, all that boring "office" stuff - there was no development environment that you could access via ViewPoint, so it's not that much fun to play about with. When you've done one document you've done them all :-) The development environment was usually installed in a seperate volume on the machine, and went by the name of "Tajo" or "XDE" - this was another window-based environment with all the good stuff like a Mesa compiler, debugger, file browser etc (guess which environment I used the most!). If you knew the magic runes you could set up the debugger/development volume to "debug" the VP volume and be able to swap between the two, but it could be a bit of a pain because a clean VP boot would take around 15 minutes :-/ Xerox attempted to market VP standalone after it was clear they'd missed the boat as far as mass adoption of Star (another 914 it certainly wasn't) - they had a version running on Suns, my memory's a bit hazy now, I think the project was called "Salient" and involved the use of the "Portable Common Runtime" - basically a Mesa virtual machine(?). They also had a version for Windows - I think it originally ran on a separate Mesa processor card and then later they implemented a complete software Mesa VM to run VP/GV on. Unfortunately they still didn't get many sales, and the rest is (literally) history. Star RIP. [Incidentally I still use it on my laptop, Star still gives Word & co a good run for their money! There's at least one corner of England that is "forever Xerox" :-)] The 1186 was much more straightforward - the processor was microcoded for InterLISP-D, which took up the whole machine. Ran like a dog, but was very nice to play around in (assuming you could handle all the brackets) because of the GUI. Personally I liked Mesa way better. A bit of Xerox folklore for you :-) Aparrently the 6085/1186 case was designed to look like the Xerox Tower in Rochester, NY... can't see much resemblence myself, other than it's tall and thin(ish). What do I know though, I'm just a dumb programmer not an "artist" :-) Cheers Al. PS always on the lookout for old Xerox stuff myself - unfortunately I'm stuck in Bath (UK) and they're are hard to come by as Bill Gates fans on this list :-)

(Fwd) Mother lode of donations in NJ

by lgwalker＠look.ca

This was on the Mac Evangelist. Anyone qualifies, respond to original post, not me. larry -------------------------------------------------------------------------------------------------- Subject: [FYI] Macs to Donate From: "Steve Chambers" <schambers(a)sarnoff.com> Date: Sat, 21 Apr 2001 03:09:06 +1000 Folks, A while back I had posted a message here about some Macs that my company (Sarnoff Corp.) can donate to any registered non-profit organization. The person who was responsible for arranging for the physical transfer never followed up with the contacts I provided him. That person isn't with the company any more and I can now proceed with this donation. So if there are interested parties out there: 1. you MUST be in the local area (Princeton NJ) because you are picking this stuff up yourself 2. you MUST be a registered non-profit organization and be able to provide proof of that to me 3. You need to arrange pickup of the equipment ASAP. Preference will be given to people who can pick up the equipment the week of April 23-27. You will need a 12-foot u-haul (or equiv, perhaps larger) for all the equipment we have. We will bring it to our loading dock but it is up to you to get it in the truck. Below is a partial list of equipment to donate: a number of working and non working 6100/7100/8100/7500/8500 Macs. A few older ones as well. A number of PowerBooks in the 100 series. Several monitors of the 17" and 21" variety, all working as well as a couple of smaller ones. Note that there are not as many monitors as Macs by half. 3-4 Laserwriter-II printers all (presumably) in working order. A boatload of cables, keyboards, mice, transceivers, phonenet connectors, batteries, PowerBook ac adapters and the like to go with the aforementioned computers. *PLUS* A _Large_ inventory of Apple Service Parts to repair printers, desktop Macs and PowerBooks. All working Macs have an OS on them but nothing else. The OS is the one that was on it when it was last used and all that was done was our software and settings were removed, so the OS on these Macs is probably not complete, but is sufficient to boot the Mac. There is a *LOT* of stuff here folks. There also is the possibility that some more CPUs and monitors will come available at a later date. Please respond via email only (no calls please) with some info on your organization and how soon you can take this off our hands. On a personal note, I recently experienced a hard drive crash and have lost the email addresses of the people who have responded to the previous requests. So if you have contacted me before about this do so again as I don't have the contact info any more! cheers!

3Mb Ethernet

Also Eithernet AKA 802.x was never that slow. The > 3 mb/s stuff I'd always called ARCNET. ARCnet is different, it's a proprietary system, not at all the same as the original 3Mb/s Ethernet, which is sometimes referred to as "Experimental Ethernet". BTW, ARCnet is 2.5Mb/s, not 3Mb/s. Instead of CSMA/CD access control, it uses a token-passing system, rather like Token Ring or FDDI, although it's a bus (like thick Ethernet) not a ring. Which is why its other name is Token Bus :-) The original Experimental Ethernet is very similar to 802.3 in many respects, including the topology, CSMA/CD, and several other things, but not in details like addressing, packet framing, packet length. I think it uses 75-ohm devices rather than 50-ohm, but I've never seen a live 3Mb/s system, so I can't be sure. It led directly to the DIX (DEC-Intel-Xerox) consortium's Ethernet specification, which in turn led to the 802.3 standard. If you want to read the original spec, the relevant paper is at http://www.acm.org/classics/apr96/ -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Oddly enough (have to toot my own horn here) when I was in my late teens/early wenties, I worked for a tiny (floated between 2-5 employees) desktop publishing and database application development firm called Princeton Desktop Systems, Inc., now based in Trenton, NJ. (see http://www.billtrak.com for what they're doing now) When I was with them, this company did everything from building custom PeeCees (the '386 had just come out) to refilling toner cartridges to producing camera-ready copy for newsletters and such. This company was founded by, and is owned & operated by, Gerald J. Clancy, Jr., the guy who chaired the IEEE 802.3 committee. A funny and cantakerous fellow, he's an absolutely brilliant programmer. Earlier in life Jerry was one of the principal developers of OS/360, and also spent some early time at Honeywell. I learned a tremendous amount from him during the 3 or so years I worked there. His "old school" computer science background affords him a depth of understanding of algorithms and data structures that no WhizBangCollegeBoyVisualBasic weenie could ever hope to achieve today. I count myself as extremly lucky for having had a mentor of such caliber. -Dave McGuire

Using a 1.44MB 3.5inch floppy on an old controller

Odd old Xerox equipment

by optimus＠canit.se

I often walk by a company dealing with artificial intelligence, who have the good taste of decorating their offices with Rietveld chairs and vintage computer equipment. Today, I happened to notice a very sexy Xerox machine. It was a black, rather fat tower with a very black front with relief stripes. On top of it sat an equally black diskdrive, its front as black the computer. I think it would fold down to reveal the actual slot. The back featured a number of very large blanking plates for graphics (I think a D15) and AUI. What kind of system was it, when was it released, what OS did it run? Can I marry it? -- En ligne avec Thor 2.6a. Computer programmers know how to use their hardware.

I would strongly advocate leaving one of the three inputs (L1, L2, L3) open, and connect the other two to P1 and P2. This makes a full-wave controlled bridge rectifier across the "220" line. The peak voltage (hence the no-load DC output) would be 220 sqrt(2), about 340V. The DC output is floating with respect to protective ground, but will be isolated by the transformer in the switching supply that runs from the nominal 300V. carl (amateur electrician) -- carl lowenstein marine physical lab u.c. san diego {decvax|ucbvax} !ucsd!mpl!cdl cdl(a)mpl.ucsd.edu clowenstein(a)ucsd.edu

FS: IBM 6157 external tape drive and heaps of tapes - System/36??

by rhblake＠bigfoot.com

I have just come across an external tape drive that appears to be in good shape with a huge box of DC-300 tapes, 60 of them. All appear to be used, all but a few are in plastic cases. It all looks to be in good shape and the tapes came in a box marked "System 36 tapes" and to the best of my recollection that's what the tape drive goes to. Any offers? The drive is light but the tapes probably weigh 40 lbs. I'd ship it by UPS gorund so it's cheaper. At present I'd prefer to stay with shipping in the US. Drop me a note direct to rhblake(a)bigfoot.com

Hello all, Today I stopped by Goodwill on my way home. I saw a rather odd piece of IBM equipment. It looks like a large black IBM typewriter connected to a large black box by a heavy cable. It is labeled "Mag Card II". What is it? I doubt they'll ever sell it, as they have it at $59!! Chad Fernandez Michigan, USA

Need help on DEC cards & drives

by Innfogra＠aol.com

Hi; I need some help IDing some DEC cards; What is a PMAG-E & a PMAD A used on? How can I identify the quantity of VRAM on the PMAG-E? What is the small memory card on the same? All the slots are full. How big is a RF35-EA drive? RZ25, RZ26 & RZ28? How much memory on a M7622-AV, a M7622-AP and a DataRam 63015 (180010002)? These are in the VAX 4000/200. How do you open the case on the 4000 to see if it has any drives? I got the front panel open. Is an Emulex QD2110202 a Qbus ESDI or MFM drive controller? What is a Microtech MT CIQBA+? How much ram does a M7608 BS have What is an AH-132-06? 6 wide card, prob. Unibus. One is marked CPU Nissho. What is DEC MS02-AA memory used on and what size are they? Thanks for all help. If anyone is interested in purchasing any of this please contact me offline at whoagiii(a)aol.com. I will ship overseas. Paxton Portland, OR PS Also available is an MT external case with an Exabyte 8200 tape in it, a couple SZ 12X (an LA & an EA) Drive cases for 3100s, a Todd SCSI 1 CD tower with 4 Hitachi CDs (came in with the DEC) and a storage works drive tower with no sleds or drives.

BCD accuracy (was: HP 85/Rocky Mountain BASIC replacement)

by ajp166＠bellatlantic.net

From: Jim Battle <frustum(a)pacbell.net> >Unless you are doing financial work where the fractional numbers tend to be >inherently decimal, BCD arithmetic, for a given number of bytes of storage, >is less accurate than binary. As a BCD byte can represent only 100 states >vs 256 for binary, you are going to lose more than one bit of accuracy per Sinppage.... Never confuse accuracy with resolution or range. Most BCD systems were less prone to truncation, rounding and other cumulative errors within their range. Binary for the number of bits gave more resolution but sometimes at the expense of accuracy. >So, OK, 0.1 (base 10) can't be exactly represented in a binary format, but >0.11111 (base 16) can't be represented exactly in an 8B BCD representation. If you meant .1 and got .11111 that would be a significant error! same for say meaning .1 and getting .09999. Allison

This sounds like a Xerox 6085 although I don't remember the case being black, more like a dark brown IIRC. If so it is the second generation Star machine, I can't remember its name right now (Daybreak? someone will correct if I am wrong). Needs it's own monitor, keyboard and mouse. Look around for those. Highly collectable. Get it if you can. If you are close to Portland I would be interested. I miss getting rid of the ones I had. Runs a Xerox operating system called Viewpoint. Look for Version 2.0.

True but the first reason given is the one that was DEC designed. At the time the Infoserver was flown a Cdreader was 1200-1800$ for a 1x! and it was thought a group could effectively share a library of them. In the late 80s early ninties that was very true.

Zenith CPM-80 manuals????

by rigdonj＠intellistar.net

I bought a huge pile of manuals today. (Including LOTS of HP manuals :-) Two of the manuals are marked Heath Zenith and they contain unretouched copies of Digital Research's various CPM-80 version 2.2.04 manuals. Only the outer cover pages of the manuals have been changed. They are now black with white and grey lettering and Heath/Zenith's name on them. Some of the manuals are still in their original shrink wrap! There are also two original hard sectored 5 1/4" floppy disks in the back of one manual. The binders are also black with white and grey lettering. Does anyone know what system these are for? Unlike the Z-100 manuals these are completely generic. There's no mention of what system they're intended for. Joe

DEC (Minc 11?) RX01 disks and PUTR

by donm＠cts.com

I have been asked to see if I can transfer the contents of some 8" disks to PC compatible disks. A CP/M disk has offered no challenge, but I am stopped dead on a disk whose label indicates that it was for use on a DEC Minc 11. Using PUTR, I have tried mounting the disk as /RX01 and /RT11, /FOREIGN, and even /OS8 at separate times. However, whenever I invoke the COPY/DEVICE command it selects the disk and errors out with the message 'Sector not found reading drive H' 'Abort, Retry, Fail?'. Using AnaDisk, I am able to determine that there are 26x128 byte sectors per track, but with a data error message for each sector. Considering some of DEC's strange format characteristics I am not too surprised that AnaDisk has a problem with it. But PUTR's problems do surprise me. Another disk gives exactly the same result. It is certainly possible that the disk is simply bad, but could there possibly be some other operating system format that is also 26x128 but does not respond to PUTR and the options that I have tried. Thanks for any hints that you can offer. - don

Longest running user group in history?

by r.stek＠snet.net

The Connecticut Computer Club has been meeting monthly (except July & August) since 1976 (and maybe '75 - I was up in Saskatchewan until '82). Steve Ciarcia started it and we met at a local library until about 1983. Since then we turned it into a dinner meeting (everywhere from Denny's and all-you-can-eat places to nice steak houses and Italian restaurants). When Steve was an editor at BYTE, he usally brought a current project and was always looking for ideas for his monthly projects (I led the HAL-4 brainwave biofeedback unit design group), but everyone participates in various and sundry ways. It's much more a hardware group with several engineers from Prattt & Whitney and other local engineering shops. But, and most importantly as acknowledged by everyone, it's almost always a good meal! <g> Bob Stek Saver of Lost Sols BTW, Steve thinks I'm nuts for spending so much time on the 8 bitters!

HP 98730 DaVinci Framebuffer ?

by jarkko.teppo＠er-grp.com

Hello! Does anyone have any docs or information on a HP 98730 (TurboSRX?) framebuffer ? To make a long story short, I have one of those boxes and it's really usefull in showing it to normal PC users that "Oh, that's just a graphics card" (it's a HP minirack module, about 30cm high and weighs around 20 to 40 kg). It's a *real* framebuffer :-) The problem is that I have a DIO-I card 98720 (it's the same size as a normal DIO-II card but it doesn't have all the connectors) and it's connected via the LGB (Local Graphics Bus) to the 98730 but I can't get X working, neither in hp-ux or NetBSD. Normal ITE console works but graphics won't. So, do I need something else than the 98720 card ? I've only read about cards like VDMA (virtual DMA) and like. If someone can help me out here I'd really appreciate it.. -- jht

International Microsystems 1010 Programmer

by r_beaudry＠hotmail.com

Hello all, Recently I purchased an IM 1010 Universal PROM Programmer, serial number 448. It has one personality module, HAGEN1 1, and one adapter, 512x8. This is an old programmer (somewhere on the order of 20+ years old), but it still appears to function. The manual I received with it, however, was basically just a device support list, and did not contain any operating information. I opened the device, and lo and behold, an Intel i4040 was inside, along with some other Intel 42XX chips of that family (MCS-40, I believe). There were also several TI 2516 EPROMs, some RAM, and discrete stuff. I did not disassemble the display or keyboard. A serial port is on the back, and the unit came w/ a serial cable, but I have not hooked it up to my computer yet ..... I powered it up, and it appears to function. The display lights up, and by playing with keys I can get address counters on the display to increment, and I think I can store values in RAM.... - Does anyone have an operations manual for this programmer? I would gladly pay copying and postage... - Does anyone have personality modules and adapters that they'd be willing to part with? :-) Or perhaps schematics for some of them, so I could build my own? This beast supposedly could program 1702s and 2708s with the right adapters, so if I could make those, I'd be VERY happy.... Thanks! Rich B.

VAX 6000 3-phase conversion (was: Re: Three Phase)

by gunther＠aurora.regenstrief.org

Sridhar, here is the URL to this material: http://www.decvax.org/vax6000/power.txt I have tried to mail the wizard who writes the in depth stuff, but his email address is no longer valid. So, what you see is what you get. I have thought about this again last night and came to a conclusion that I should just try it out. DISCLAIMER: I AM NOT COMPLETELY CONFIDENT OF THIS AND I HAVEN'T TRIED IT OUT YET. SO, READ ALL OF THE BELOW CRITICALLY, DON'T JUST TRUST ME BUT THINK FOR YOURSELF. PLEASE LET ME KNOW ANY CONCERNS OR DOUBTS YOU MIGHT HAVE ABOUT THE CORRECTNESS OF WHAT I SAY BELOW. Let's look at the plan again: ____________________ +300V | | | -__ -__ -__ thyristors ^ ^ ^ | | | L1 ------* | | L2 -----------* | L3 ----------------* | | | - - - diodes ^ ^ ^ | | | --------------------- Return ---- FOR 220 V SINGLE PHASE ----------------------------------------- With a 220 V single phase power supply (P and N coming out of your receptacle,) as in Europe, Australia, India (?), etc. all you would need to do is, e.g., put P on L1 and N on L2. That gives 220 V ~ input and if this sqrt(2) rule is correct (which I'm still a little confused about) you get 220V * 1.414 = 311.8 DC, i.e., just right. As Leon, the lost wizard of ZA, assures us, the thyristors and diodes are dimensioned so as to withstand all the power load coming through L1 and L2 only. If we want to be double sure, it should not hurt to, say, splice the P (or N) and connect to both L1 and L3. Of course it doesn't matter where exactly you put P and N and which of those you distribute over the two input lines. My guts suggest to splice P on L1 and L3 and N on L2, but that's for no rational reason. Also, I would not want to miss connecting the protective ground to the metal cabinet (wherever the protective ground should connect at the AC input, which I'm not sure about.) ---- FOR US 2 x 110 V TWO PHASE ------------------------------------- For the US I am thinking that may be the 2 phase 220 V dryer hookup is the best way to go. Not only is this line at a convenient location where you can store a big cabinet like this one, it is also well dimensioned to sustain a VAX or (and may be AND) your dryer. Otherwise, just dry your clothes on a line. But do not mistake the VAX's blower with your front-loading washer :-). Seriously, the two phases here, as I understand it, are: ------- P1 ------- N ------- P2 with U peek = 110 V and the phases of P1 and P2 being displaced by 180 degree. So, if you measure U between P1 and P2 you get 2 x 110 V = 220 V. So, I would then connect it like this: ____________________ +300V | | | -__ -__ -__ thyristors ^ ^ ^ | | | P1 -L1 -----* | | (N)-L2 ----------* | P2 -L3 ---------------* | | | - - - diodes ^ ^ ^ | | | --------------------- Return I am not sure whether to use N on L2 or leave N open (again, I notice how much I forgot about my high school physics.) This actally bugs me, because I don't know quite where to connect to the ground potential and how to deal with the protective ground here. I *think* that when I have the N connection open, I will have a higher DC output than when I close N on L2. But I don't know. Can someone throw in his opinion on the matter? I should at least be able to try this out without being afraid of breaking anything, since P1 P2 alone work just like 220 V European power. At least, I am using my old German electric devices on this kind of power hookup from my 60 A extra two-pase line.

OT: 25 SIGNS THAT YOU'VE Had TOO MUCH OF THE 90's AND 2000

by mmcfadden＠cmh.edu

Our power was off for 4 hours in a recent thunderstorm and the first thing I tried to do when it went off was try to login to look at the National Weather service Doppler image of the storm. My UPS keeps the cable modem and router up but the PC was dead. I was holding a flashlight in my mouth when I tried. It's actually pretty neat to see the image and recognize that the storm cell is probably over my house. Mike mmcfadden(a)cmh.edu

Low ceilings and other impediments (includes floods)

by mmcfadden＠cmh.edu

Floods Our computer room was on the 10th floor of an office building and the drain for the water cooled air handler dumped into a sink in the hall next to the elevator. The cleaning crew left a mop in the sink and it clogged up. We flooded the entire area below our raised computer floor. Amazingly the PDP 11/70 and RP04 kept on running, we noticed the problem because of the humidity in the room when we came in. Nothing like mold covered cables in raceways. We tried wicking the water out and blowing hot air under the floor, the mold really liked the hot air. Being on the 10th floor surrounded by low buildings we used to estimate how many mag tapes we could braid together to escape from a fire, we knew the ladder trucks couldn't reach us. We also estimated the disk safe with our backup disks would probably end up on some lower floor. Mike mmcfadden(a)cmh.edu

strange find!

by rigdonj＠intellistar.net

I helped a friend of mine pick up a load of surplus stuff today and one of the items that I got was a bag of keyboard overlays that came from Tektronix. The Tektronix tag on the bag is dated 1973 says that they're for a PDP-11! The overlays appear to be for a numeric pad or something similar. They have cutouts for four rows with four keys in each row. The overlays are all marked as "User Definable" so the key positions are unmarked except for Cont, Reset and CPU Busy in the last three positions in the bottom row. There are four orange color overlays, five yellow overlays and five blue overlays in the package. Does anyone know what these are four???? Joe

I guess if the early 1970's counts as fairly late, anyway... I can't speak for the 60's, but in the early 70's Samsonite (yes, the suitcase people) had a plant in Englewood making an 18 bit minicomputer. They called the company Electronic Processors, Inc. Colorado is more of a semiconductor fabrication area, really... Though I'm sure most people on this list will recognize Otrona...

Some versions of Solaris don't honour that, though :-( They just use it to contain a message given to anyone attemting to log in while a shutdwon is in progress (it's not the message printed to active sessions when a shutdown starts, though).

Latest finds - Tandy 1000 and "Code Name: Sector"

by ethan_dicks＠yahoo.com

The Tandy 1000 was a freebie (from a friend from a cow-orker who wanted $20 for the dot-matrix printer, but the computer was free). The other item is a Milton-Bradley electronic sub hunt game from the late 1970s. Electronically, it resembles Mattel football and the like - a window of LED displays, a few discretes (to indicate cardinal points on a compass) and a bunch of buttons. The manual is present with a tutorial. Apparently, you reset the thing, then plot ship courses with crayons on a grid map, punching buttons all the way. I can't imagine trying to _actually_ play the game, but playing *with* the game was fun for at least as long as the tutorial lasted. Oh... the game was $0.67 at a thrift store because it was 75% off day for green tags. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

TK70 / CompacTape II anywhere?

by gunther＠aurora.regenstrief.org

Hi, where do you think one could buy new or used CompacTape II (TK70) tape cardridges? It looks as if they're nowhere to find on the net. Well, I suppose one could use the new 24 GB DLT cardriges, but they are terribly expensive just for the poor VAX 6000 hobbyist. I and my fellow VAXhaxer appreciate any help, thanks -Gunther

small TCP/IP package installation question (in RT11)

by GOOI＠oce.nl

OK. Thanks for all the advise. I am using PUTR too, of course. Unfortunately, the firewall of our company does not allow FTP.... Lucky me that I bought the RT-11 Freeware CD-ROM from Tim. On it is the small FTP and Telnet package as well, in a .DSK and as a directory with the seperate files in it. Saves some download time. > BTW, one word of advice, follow the instructions to very > carefully, you'll save yourself a lot of headaches! So, I guess I will encounter the same pitfalls. That is okay, in such a scenario you learn the most. Struggling with some problems is half the fun, isn't it? Then there is always ClassicCmp .... -Henk.

Now someone has found the name of the file from the classiccmp archive and has ask me for a copy of the file. I can't find it on any of the computers I have up and running, or on any of my back-up CDs. Would someone that grabbed the file two years ago, please send it to me or put it up so I can grab it.

OK, in this case it may be more a question of convenience, but if Ram has the access (ie, access to the root account) to do all these things, he would be better to either do as Gene suggested and "touch /etc/nologin" (or put some text in it: the contents are printed by login before it closes the connection), or to do it properly and run tcpwrappers, with suitably set up /etc/hosts.allow and /etc/hosts.deny files -- then he can control who can connect, from where, and using which protocols (telnet, rlogin, rsh/rcp, ftp, ssh, etc). If you *are* thinking of security, remember that inetd only controls some network services -- some, like SMTP, HTTP, SNMP and others, normally run as daemons in their own right. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Anatomy of a VAX 6000-420

by gunther＠aurora.regenstrief.org

Hi, as promised here is my photo series on systematically disassembling a VAX 6000-420. I do not envy you poor folks who thought simply taking out the card cages and the cab kit would allow you to somehow put this back together to a working machine. Has anyone ever actually done this? Anyway, here is my VAXian anatomy page: http://aurora.regenstrief.org/VAX/anatomy BTW: I (and a few friends) am still looking for advice on how exactly to convert the power unit so as to hook a VAX 6420 on 110 V houshold power. Either 110 V single phase or 240 V 2-phase would do. I have done electronics in my youth, but I have no clue how to go about it and don't want to go trial and error :-) Any help is appreciated. regards -Gunther

Is there a way to disable rlogin or telnet over to my > machine? Yes, it's easy. All network-based services like that usually have their server-side components run by a supervisory program ("superserver") called "inetd". Inetd listens on all the ports that services are registered for, and when a connection request comes in, inetd accepts the connection, starts the required server binary, and basically hands it the socket. From then on, that connection is handled by the server binary for that particular service. This whole operation is handled by a config file called /etc/inetd.conf. It's got one line per service, and each line has many fields that control different things. The first field is the name of the service (telnet, ftp, etc). You can comment out services in that file by inserting a "#" in the very beginning of the line in question. To achieve the results you want, I would comment out the following lines: telnet (handles incoming telnet connections) ftp (handles incoming ftp connections) login (handles incoming rlogin connections) shell (handles incoming rsh and rcp connections) I hope this helps. -Dave McGuire

Only thing that doesn't work (as far as I know) is the battery pack. Also multiple printers, ribbons, thermal paper, a spare screen, keyboard, maybe a floppy and expansion port thingie, system boards, etc. I also have Wordstar that runs on the DGone, a few boot (MSDOS) disks, and GWBasic. Free or cost of shipping (Northboro, MA) if I get one interested party. If I have more than one, it'll be an auction to see who wants it most.

data book rescue (nearly)

by kebabthesheep＠yahoo.com

The TV-fiddling part of my group here at work just moved house, and as is usual, when moving offices they dumped stuff. Specifically about 50-60 data books mainly covering philips devices. There are quite a few interesting ones as well covering all manner of bizarre video processors, and well as mundane stuff like diodes, mosfets, power controllers, memory ics, semi-custom gate arrays - you name it :) Looks like the future got a bit brighter w.r.t. to finding out data on those obscure devices you find in monitors, and old computers :) I'll make some sort of list when i've got them all out of my office - pity my only means of transport atm is a 40 year old brit bike...

At 2mhz clock it wants 500ns or so rams, at 1mhz you can use 1uS (1000ns!) parts easily. If the writer cant find any let me know... I have some. Allison

Sheesh indeed. :) It's worth more as it is actually a fairly useful machine as is and easily expanded . Certainly worthwhile to repair or even restore. Allison

So too with LINUX! The nice thing about Windows is - It does not just crash, it displays a dialog box and lets you press 'OK' first.

Pro350/Pro380 Monitor

by dittman＠dittman.net

Can a Pro350/Pro380 use a VR241 monitor using the built-in video (in mono-mode, of course), or does the VR241 require the color daughterboard? Also, does anyone have a spare daughterboard for sale? Thanks. -- Eric Dittman dittman(a)dittman.net

Tektronik 8560 System

by chugiang＠juno.com

I have a couple 8" floppy disks that. I believe that the system used for these diskettes was Tektronik 8560 System and these OS was Tnix. I want to transfer data from those diskettes to another media. Does anyone know or have any recommendations?

RT-11 - An Open letter to Mentec?

by dburrows＠netpath.net

>I am sad to hear about this, especially for you personally as well as for the >business loss. Is there any hardware that you need but now can't get? >Are there any RT-11 problems that I could help with? Sorry - I would >not be of any help with RSX/RSTS/VMS. At the moment things are basically under control. I had a system in my van that was to heavy to unload by myself and I had 5 pallets of equipment waiting to be picked up at a local friends place that has a nice loading dock. Thankfully the kids are all grown and moved out of the house so I have taken over half the house while the mess gets cleaned up and a steel building put up. > >Can you at least describe the overall probable contents of the CD and >also tell us if the contents are based on availability or because Mentec >did not want the omitted distributions on the CD? Namely, if the omitted >items became "available", could they be included? While the actual >distribution versions would be the best indication, a simple statement >that there will be RT-11 distributions would help as well. And are >the layered products being considered like FORTRAN and BASIC? There are many different distributions and IIRC some layered products. I have not looked closely at the RT11 stuff for a while.

I have had several thoughts on that and it will depend on time. It will be DOS, etc. readable. >Hopefully, this was not the trickle situation and these posts on classiccmp >are the best way and do not involve Mentec in any manner. I only jumped in because I did not want a bunch of people calling Mentec about it now. I am waiting for something and hope it will be here before I get tied up on service calls for the next 2 weeks. > >Can you use any help? Have you a new target date at this point? Any >information would be helpful since probably most of us were not aware >it was even being considered. In fact, can you take a few minutes and >describe what is being considered? It is basically finalized but I don't want to have people rock the boat and be calling wanting this and that added. It has been enough trouble to get it to this point and everyone agreeable on its current contents. I have wanted to include things but it will not be another DECUS type distribution. The goodies like Al Baldwin's TCP package will not be on it. ( I tried but things were to cast in stone when I got involved) > >I would certainly be willing to help with anything that I could do at my end. >I have both real PDP-11 Qbus hardware available with a SCSI host adapter >with both SCSI hard drives and Sony SMO S501 magneto optical drives >and a number of 5 1/4" disks which hold about 295 MBytes per side >(about 8.75 RT-11 partitions).

I have a couple 11/84's, 11/44's that will be up when time permits. These are all also on the network with the PC's and a 4100. Remember I make a large part of my living supporting customers that are running this hardware. Dan

small TCP/IP package installation question (in RT11)

by GOOI＠oce.nl

Hi all. I am trying to install the small FTP and TELNET package in Ersatz-11. I downloaded the smltcp.dsk and dvrdsk.dsk image files. However, when I use PUTR, I cannot "DIRIRECTORY" the contents. Example of screen output: (C:\E11)>mount ld0: dvrdsk.dsk ?Unable to identify file system (C:\E11)> (C:\E11)>mount ld0: dvrdsk.dsk /RT11 (C:\E11)>dir ld0: Volume in drive LD) is RB 03-JAN-97 Add SPFUNs Directory of LD0:\*.* 18-Apr-2001 ?Corrupt directory (C:\E11)> Perhaps it is just a simple thing I overlook, but whatever I try it looks like the DSK file is bad. I downloaded the file with Netscape 4.76 and right-clicked on the link and choose "Save link as..." from the pop-up menu. BTW, the page is http://shop-pdp.kent.edu/sshtml/tcpget.htm Kind regards, Henk Gooijen, PDP-11 collector Sneak-peek of retro-computing: http://home.12move.nl/~sh416008

Collection list (just for phun)

by Alan.Pearson＠cramersystems.com

> I have to say that this is one of the most interesting topics that > we have discussed lately and it ereminds me why I actually > joined the list in the first place! Yeah, it's great to see what stuff people have got, I agree! I only joined the list a couple of weeks ago, and don't have anything much of a "collection" as such (just the usual stock of home micros, mostly stuff I got from new and never had the heart - thankfully - to throw out when they stopped being used) - Sinclair, Acorn, Commodore etc. Probably the only "interesting" one in the lot is an OU Hektor1 (someone else just posted about one of these 8085 boards). I'm in Bath (UK), and so far haven't found a decent source of old machines in the area - computer scrap/surplus dealers seem a bit thin on the ground. > Another thing I would find interesting is/are lists of what people are looking for.. I'm interested in older workstations (mainly stuff I've worked on in the past) and am always on the lookout for spares/complete systems/manuals/software etc - basically anything :-) Of most interest are: Xerox Alto (fat chance of finding one in the UK though!), Xerox 860, Xerox D-machines (8010, 6085, 1186 etc) Sun 3/60 Sun 4/110 Sun SPARCstation IPC HP9000 (725? can't remember the model number now) ICP/3RCC PERQ Cheers Al
