What are you considering new? I am looking at the Ultrix 4.x Basic Installation guide dated 1990 and it lists over a dozen uVAX's, VAXservers, and VAXstations. > AFAIK Ultrix 3.0 was current at that time. Sounds about right. So it would seem OK to say that these tapes I have are for VAX. Looking at the tapes: 1) Ultirx-32 V2.0 16 USR TK50 1987 My question here would be was this the only tape needed to install this version? 2) Ultrix-32 V2.2-1 Supp TK50 1988 With this tape marked 'SUPP' I suspect that I only have the one tape of a multi-tape set. Well, someone else on the list was asking if I had any versions of Ultrix for VAX. I guess it looks like a possibility. Thanks, Mike

Blank Paper Tape Question

by bill_r＠inebraska.com

Does regular paper tape normally come with the sprocket holes pre-punched, or does the device that punches the data holes also punch the sprocket holes? I recently bought some "paper tape" from eBay, and it looks like the right stuff except it's totally without holes. I don't think I've ever seen "virgin" tape before, but I had the idea that the sprocket holes down the middle came with the tape. I'm kicking around trying to build my own tape punch, since I have been unsuccessful at scrounging or buying one so far. I picked up some stainless steel flat and some rod of the appropriate diameter for the holes today, along with some solenoids for actuating said rods. I'm thinking of machining the stainless to make my own punch, but the lack of sprocket holes on the new tape has me confused. Do I need to add another solenoid and pin to punch a smaller hole for the sprocket, or did I just buy some odd-ball tape?

A proposal for a definitive URL linc source site

by lgwalker＠mts.net

I've spent some years on the net searching for info on my latest acquisition and how to get it functioning. In the mutitude of sites available some provided useful info on the machine or platform while others simply supplied pictures of a collection. Sources could lead you to a multitude of sites before you found the one that answered your questions, if you were lucky. The problem is the common problem on the net of too much information. Sellams site is a case in point, and IINM my site-list from T3C served as a source for his some of his list. The multitude of sites is just too overwhelming. What would be good is the definitive computer site for each computer or the catagory you're looking for. Jeff Helliges site for the Tandy 2000 http://www.cchaven.com Tim Manns TRS80 site http://www.tim-mann.org/trs80new.html Kees Travers TRS m.II http://home.iae.nl/users/pb0aia/cm/modelii.html Merch's site for the m.100 ( Can't find it in my list.Put it in your sig file Merch) For the CoCo http://zeppelin.tzo.cc/coco/coco.jhtml Tandy 1000 page (can't find it- Red dog page ?) As examples just for the Tandy boxes. comprehensive sites like the PCjr one http://mail.magnaspeed.net/~mbbrutman/PCjr/pcjr.html or any of the PS/2 Mafia pages and the IBM Can site for most models It would still comprise a multitude of info but would point you to the best sources of info on that box you just acquired. And of course generate a bunch of disagreements on the list as to the most authoritive site. Sellams site would likely be the best place to list such a thing as it is well- known and would likely need only a minimum of re-organisation. And of course could have various sections for those into micros, minis, and even mainframes. Rogers site could be a kickoff for Laptops. The main thing would be that the listing was the authoritive site in the opinion of the list, and save a collector from tedius Google searches. Possibly even a rating system could be used.

Intel RAM - What came when

by gmphillips＠earthlink.net

Can anyone here help me with this. I need to know the sequence that Intel RAM (SRAM and DRAM) was introduced. If you think you know dates, give them. In know that Intel's first RAM was the 3101 SRAM Then came the 1101 SRAM I "think" the 1103 DRAM was next. Then comes... What? I suspect the 2101? Or was it the 2102? Not sure which came first. I think the 2111 and 2112 came after the 2102. Anyway, if you can help, let me know what order you think the Intel RAM was introduced. I've tried figuring this out from the 1977 IC Master but it list everything up thru the 2114 and does not indicate when the chips were introduced. Here's the base numbers I'm interested in. 1101 1103 2101 2102 2104 2105 2106 2107 2108 2109 2111 2112 2113 2114 2115 2116 2117 2118 2125 2148 2149 3101 3102 3104 3106 3107 5101 Also, if you know of any early Intel RAM not listed, please let me know. As always, I am looking to buy any vintage Intel or Intel 2nd source processors, EPROM's, PROMS's, ROM, RAM, or support chips you have, that I don't, that you don't need. In particular, I'm looking for the following: Intel C1701 EPROM Intel C1702 EPROM (not C1702A) Intel C1602 PROM Intel C1602A PROM Intel C3101A in white CerDIP package without visible gray traces. Intel C2704 EPROM Intel C8080 (not C8080A) Eng Samples of Intel 4004 thru 8088 processors. Toshiba TMP9080AC (8080 clone) Mitsubishi M58710S (8080 clone) Early AMD 8080's before AMD started using the AM9080 part numbers.

2 qbus cards available

by William.King＠dadaboom.com

I have the following two boards which I like to dispose of. Free to a good home, as long as you don't put them up on eBay. Buyer pays shipping, let's say $5.00 each. 1. Computer Products Model 312 w/cabinet kit. I believe this is a DHV11 clone (dual width, qbus). The cabinet kit has 8 DB25 connectors. 2. Simpact Assocates, Inc. ICP 1622 Comm (quad width, qbus). I have no idea what this card is, but it does have a socketed DEC 21-17311-01 chip on it (which I believe is the bus interface.) I imagine that it is a communications card of some sort. Both cards are untested and shipped as-is. The ICP 1622 was pulled from a working system, so I'd guess that it works. The other arrived with a pile of equipment, so I have no idea about it's status.

VAX 6400 booting saga: A scary story with a happy ending.

by gunther＠aurora.regenstrief.org

Hi, let me share a frightening story with you that I lived through while my family had naptime. I decided to try out Isildur's idea of booting Ultrix using a KA62A processor in the hope that that would be supported right off the 4.5 boot tape. And I just happened to have one such T2011 board in a box (taken off a lonely 6310 in a barn full of bird-poop.) So, I took all 6 KA64As out and stacked them on some papers that I use to pack most of my boards (with papers between the boards so they would not stick together :-). Put the KA62A in and fired up. A lonely light lit and no real function was to be observed. I moved all 4 MS65A-DA boards out too, because I figured that may be a KA62A doesn't know how to deal with MS65A-DA. I swapped in some of those T2014 that seem to multiply while stored in the box. Anyway, it still wouldn't work. The self test progress report shows that the CPU detects no memory and then it reports that problem explicitly and stops. The CPU error status lights say hexadecimal C0. I could not find any table explaining what C0 status code is. It could be boring (like "no memory found", which I know) or it could indicate some condition that I could fix, like "backplane wiring error" :-). I stuffed the whole XMI bus full with those 32 MB cards in the hopes that one would work, but to no avail. So, perhaps the memory access path in that CPU board is broken? Is there any rewiring to be done when converting a 6400 down to a 6200? Anyway, my daughter came downstairs indicating naptime was over and so it was time to finish up. KA62A and all MS62A back in the box and all 6 KA64As and 4 MS65A-DA back into the bus fired up and all processors were indicating they were somehow not agreeing who would get to be the primary CPU. Hit reset and they figured it out. But now they were bitching about memory and the CPUs showed minuses in the selftest monitor. Rearranged the CPUs and the memory, still no good luck. Everything was screwed up! I was afraid I had killed all my boards by careless handling (I did this before, may be not with that polyester pullover that might have sent static sparks, like they do.) Took all but one CPU out and that did do the self test OK. But one MS65A board seemed broken. It failed regardless which slot I put it. Finally I took it all out. Then the CPUs back in and again it didn't work. I then put CPUs back one by one powering up each time to see progress. Slowly, one by one, the number of board which I thought I had killed reduced down to 1, the memory board. The order in which I put in the CPUs and the restarting every time seemed to be important. Then, finally I even found one configuration of the memory boards where all 4 were detected and tested fine. Hey I was so scared I had killed half of my VAX through carelessness. But I didn't. I am quite confused why it is all so finnicky about the order of installing the hardware. I won't mess with this machine's XMI configuration any time soon. 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

This is so > small it can be ignored, in fact many antenna systems aren't > that good. I agree with what you say here, even for the vintage of the transmitters. They were built in the 40's & 50's. It was even fascinating to see how the technology worked. To modulate a portion of the RF with low frequency (ranging from 30 to 90 hz) there was two RF coupling loops with a specially designed fan blade spinning between the loops. This changed the amplitude of the RF coupled from one loop to the other. You can probably imagine the fascination of some technicians when we swapped out this vintage tube type monsters with state-of-the-art-neato solid state units. Got questions from the some of the old timers 'Duh, it taint got no moving parts, how does it modulate the carrier?'. > As a termination a scope is a very poor match for any low Z > RF source it's impedance being 1Mohm or more so it > wouldn't matter if you plugged it in or not.

Because of the vintage of the equipment and operating in the VHF band (108-118 mhz), we had special scopes that that had a special RF input section that could handle a few watts. This was what we used to check the modulation pattens and the like. > > The open circuit at the other end of the coax got > > reflected back to the transmitter as a low > > impedance and detuned it, and the monitoring circuits > > would detect the detuning and pull the plug. > This depends entirely on the wavelength length of the > coax.

Nope, I have slept since then. They were all special designed for the government. In fact when they were replaced with solid state units (1980's), we had orders to destroy the old ones. They did not want them on the surplus market where they might show up in operation later. I do remember now, one model was built by Wurlizter (sp?), yep, the electronic organ folks. And now, I would like to apologize to the list. While this meets (and exceeds greatly) the 10 year guideline, it would not by any stretch of the imagination 'compute'. I was simply trying to point out the need for proper termination of a circuit, regardless of where the circuit is and what it does. Forgive me. Mike

CD-RW on a VMS system

by wilby98＠yahoo.com

I am looking down the road a bit on whether it might be feasible to add a CD-RW to my VMS system. My first question is if it will work with my present hardware: To be clustered: VAXstation 3100, VAXstation 2000 (will probably not be clustered, but be a dedicated disk formatter), MicroVAX 3100-30, MicroVAX II. ... and software: VMS 5.5-2 (will hopefully upgrade to latest version when get CD-ROM such as 'Toshiba XM-6401B'.) So if I add a 'Plextor PlexWriter (SCSI) and use: CDRECORD LD062 ... will I have a way to backup data onto CD-R's? How about 'performance'? I am thinking it will be slow, but how slow? -- Bill Amsterdam, NL
