All: I just upgraded servers again and this time I have a (formerly new) Compaq ProLiant 1600 rack mounted Pentium III Server. It has (going from memory) the following: dual Pentium III/533 CPUs, 512mb of RAM, a 9gb boot drive and 6x9.1g 7200 RPM drives in a RAID-5 configuration. It also has the Integrated Management Display. I forget the measurements, but it?s probably a 5U height. I also have some spares and accessories for it that?s part of the package, including rack rails (but they?re for a Compaq rack, which is different than the standard 19? rack in depth.) Right now it?s running Windows NT Server with no problems. I upgraded to a DL360 (1U) and a Quantum Snap NAS to reduce noise in the shop and to upgrade to Windows 2000 Server and Active Directory. This beast is heavy so local pickup from Long Island, NY would be preferred. If anyone?s interested, contact me off-list. I would be looking for $200 for it. I?ll throw in a 5g/10g DLT drive and cable with the sale. If I can locate the box for it I might be able to ship it but IIRC that was expensive.

ST506 / ST412 - never see any 3 1/2"?

Canon Cat HP printer driver

by awmolloy＠landsnail.com

Dwight, that is great news. I have a Cat dot matrix printer, but using an HP laser printer would be nicer. I wonder if the newer PCL 5 and 6 printers are backwards compatible? Are you using a LaserJet II? I'd like to get a copy to type in. Thanks! Andy ----- Original Message ---- From: dwight elvey <dkelvey at hotmail.com> To: cctalk at classiccmp.org Sent: Sunday, April 1, 2007 11:55:42 AM Subject: Canon Cat HP printer driver Hi All I've been able to create a driver to output to a HP printer running PCL. One needs to be able to enter the Forth mode. There were a few application softwares for the Cat that have locked out the Forth access. I've not gotten to these yet to look at how to re-enable the Forth mode. Still, most only have the normal Cat without anything extra. This code should be fine there. There is quite a bit that one can do with the Cat and just the ROM that came with it. Normally the Cat only had drivers for Canon printers and the FX80 type printers ( that were copied by several dot printers of the time ). Since the printer did formatted printing, it required a driver specific to the printer. Since I didn't have a Canon printer and was happy with my HP, I was interrested in adding code that would drive my HP. The Cat has an interesting feature in that it copies the entire RAM to disk. This means that any code entered can be made to come back on each boot without any additional operations. The Cat is programmed in Forth. I figured that I could make the needed modification my self. That was several years ago when I first got the Cat. What I didn't realize was that I had no idea how to decompile the current code or what the various escape sequences meant to the Canon printers. The first big break was finding a couple of manuals at the Stanford Special collections library, left by Jef Rasken before he died. These gave me the needed information on both the Forth and quite a bit on the printer drivers. Understanding a few other bits and pieces came from one of the developers of the Cat ( Charlie Springer ). I never did find anything other than a Japanesse document on the LIPS codes used for the Canon Laser Beam printers. I did fine some for the FX80 and the Canon Bubble Jet. With this information I've been able to determine quite a bit about writing the driver for the HP. I realize that most people would never use any of the printer escape sequences but Canon should make them a little more available. Back on subject. I've created a driver that one can type in. I've not setup propotional spacing yet but it does handle most of the needed operations. I've not looked at any of the foreign character printing yet but as long as one stays with regular the character set, it should be fine. One can use it for its intended purpose ( editor, mail list, speadsheet or whatever ) or one can put their Forth code in and print is all out on a HP with my driver. I hope to get it posted on Bruce's DigiBarn Canon Cat page but until then, if anyone is interested, send an email to me. Dwight dkelvey at hot mail dot com PS I just saw another Cat on ebay. That make three I've seen in the last year or so. _________________________________________________________________ Exercise your brain!

What is an HP1858-0054 transistor array?

by ard＠p850ug1.demon.co.uk

I am working on the reset circuit of an HP9816 computer. The output side is rrlatively conventional, but it takes an input from a chip that I can't identify. The chip is a 16 pin DIL package marked with the HP house-number 1858-0054. That's not in my equivalents list. The chip seems to have been made by RCA, and tracing the connections to it show that 2 of the pins are grounded, but none of them go to any power line. I susepct it's a transistor array, therefore (HP1585-xxxx numbers tend to be transistor arrays too). I've unsodered the chip, but trying to work out the internal arrangement is non-trivial, partly because there seem to be parasitic diodes, and secondly because I am not convinced it's just transistors brought out to the pins. There may be a long-tailed pair, for example. It doesn't match any of the arrays in my RCA databook. As I said, it's on the main processor board (the big board at the bottom) of an HP9816 computer. It's U115 on this board, at the front left corner, just behind the 16MHz clock oscillator can. Does anyone have any suggestions as to what it might be? Anyone have an HP9816 with this IC labelled with somethign other than an HP house number? -tony

OT: VCF East 4.0 lodging info

by evan＠snarc.net

Hi all, Some of you asked me for VCF East hotel info. We now have a room block at the Courtyard Tinton Falls, for the evenings of Friday, June 8 and Saturday, June 9. The address is 600 Hope Rd., Tinton Falls, N.J., just down the street from last year's hotel. The Courtyard is much nicer, however it's also pricier -- single rooms are $159 per night. Unfortunately the much cheaper Holiday Inn which we used last year is booked already (wedding season, beach season), as are similar local places. Full details are at http://www.vintage.org/2007/east/lodging.php ... make sure you ask for the Vintage Computer Festival rate. - Evan PS - I'm signing the contract tonight so wait until Monday.

So, if you run across any of those dinosaurs which have not been scrapped, crushed and melted, they could be a source. Back in the early 90's I upgraded our data entry staff's computers with new guts and the ST506 is what I was pulling out of them. If I had only known to hold on to the old drives... Jeff Walther

KANSASFEST 2007 REGISTRATION NOW OPEN KANSAS CITY, MO -- March 30, 2007: KansasFest -- the annual Apple II expo of sessions, contests, great stories, tips and tricks, fun and games, and things that "just can't be done on an Apple II" -- is now open for registration. KFest 2007 will be held at Rockhurst University in Kansas City, Missouri, July 17 - 22. Five nights, twelve meals, and countless sessions, contests, great stories, tips and tricks, fun and games, and things that "just can't be done on an Apple II" costs only $340 for a double room or $410 for a single. To register, download and complete the PDF form at http://www.KFest.org/ and follow its instructions to return it via mail, email, or fax. Wednesday's lunch (the annual Kookout) is now included in the price of the event. Also, volunteers who present sessions will now receive an on-site rebate: $15 for presenting a half-hour session, and $25 for a full hour. In addition to official shirts, sold as always at the event, there's also a KansasFest online store, where you can buy additional shirts, hats, mugs, and more. You can find it at http://www.cafepress.com/ kansasfest/ David Szetela, founding editor of Nibble Magazine and a former manager at Apple Computer, will be KansasFest 2007's keynote speaker.

"It's amazing and gratifying to me that the flame of passion for the Apple II we shared nearly 30 years ago still burns brightly," says Mr. Szetela. "I'm looking forward to attending KansasFest 2007 and re- connecting with old friends, reminiscing about Apple II milestones, and maybe sharing some little-known insider anecdotes." Come join the 30th anniversary celebration of the Apple II at KansasFest, the world's only annual conference dedicated to the first personal computer.

If anyone within striking distance of Birmingham (UK) wants an AS/400 with those all important hard drives, I've got one which you can have for the cost of coming over and taking it away (strictly pick-up only, it's far too heavy to post). I believe it's a model 9404, with an expansion cabinet - each cabinet is similar in size to a DEC BA123 cabinet, IE not that big.... And that's all I know about it, I've never even plugged it in! Contact me off list if interested. Thanks. TTFN - Pete.

homebrewed 32-bit cpu?

by Billy.Pettit＠wdc.com

Brent Hilpert wrote: Just rumour to me, but circa 1980 when I was doing some software development with the spanky new 68000, I was told that the 68000 had been prototyped as (literally) a large wall of SSI/MSI logic. Billy responds: That was pretty much the modus operandi on early MSI/LSI chips. All of the early ASIC's I worked with were bread boarded from SSI or even single gate ICs. The vendors would provide design kits with lots of these little chips. Most of them were 4 or 8 pins; a few were 14 or 16 pins. You can still buy them today to patch bugs on LSI until you can roll the metal. First ones were TTL, then they moved to CMOS. I even remember one ASIC that we used ECL gates on. This was in the early 80's. Gradually, the design software caught up and you could simulate your design on a computer. It's hard to remember that in the days before PCs, many of tools we take for granted, didn't exist. For example, when CDC was designing the Star series and the ETA machines, the early design automation consisted of huge programs to lay out the logic. The designer input the logic equations on decks of cards. I remember seeing some of these early programs taking 20-40 hours to run, with card decks of thousands of cards. I think I have a few of these early proto boards left. They would make a great display on the progress in the industry. We used a 12" by 24" size and interconnected them with ribbon cable. I never saw a wall mounted unit. But we had many that covered a standard workbench top and they later fit into a 24 pin package. Billy

PDP-6 questions

by tshoppa＠wmata.com

Seth asks: > 3) Are the stories about the Boston Computer Museum receiving a > complete PDP-6 and then chopping it up to sell as gifts truth or > urban legend? I don't know about the BCM, but I have a couple of boards from decomissioned PDP-6's. They were not disassembled out of malice but out of lack of facility to store them. > 4) Does any PDP-6 software still exist, especially PDP-6 ITS ? (I > haven't found any on Bitsavers, so I'm guessing the answer is "no") In between scraps found on the DECUS sources and some files I've cobbled together over the years from friends in the southern hemisphere, I think I have two mostly complete sets of sources for the PDP-6 monitor. I discussed this a bit on alt.sys.pdp10 last year. Get me worked up and I might actually get them to build :-). Right now they're at http://pdp-6.trailing-edge.com/ Note that most of the early DECUS LIB-10 entries are actually PDP-6 software (with occasional notes on what you have to patch/modify to make it work on a -10). I highly recommend that you browse them. Last year on alt.sys.pdp10 I also initiated some discussions about the MACRO differences necessary to assemble the earliest source files (where the syntax was slightly different). I have mentioned to Al that I am very interested in the oldest 36-bit Macro source files that he has from the LCG archives. I suspect there's at least some interesting stuff there but it's hard to sort out. Tim.

I signed the PDP-6, 4 register, bit slice board in the photo. It came from the Computer Museum in Boston where it was sold in their store Let me be clear The Computer Museum (TCM) was NEVER called the Boston Computer Museum... Boston was a temporary home when computing passed through New England, but the city itself gave nothing to it. I don't believe the origin can be traced to any machine, since there were no serial numbers, and the modification level would also be too hard to correlate with any time or place. The Museum got a large number of spares and scraps of all kinds from Digital and it was undoubtedly one of those. To my knowledge, the museum has never engaged in gutting machines for components, although I would happily agree that this is a good idea when we have duplicates and crippled or partial artifacts. As a former collector, founder, and board member of the Digital Computer Museum > The Computer Museum >> current Computer History Museum (a name I deplore and that exists only because of the way the Museum left Boston) I have always been a strong advocate of getting as many artifacts into as many hands as possible, and this includes selling museum artifacts when appropriate. In essence a whole industry of museums and collectors is essential. Incidentally, at one point there was a flame in pre-blog days about the tragedy of the museum selling boards, etc. in which I never engaged. As someone who has contributed about $10 million as well as time, etc. to this endeavor, I can only shake my head... and wonder where those folks were when the museum needed their financial and time support. The lovely ending is that the museum finally has a wonderful home and caring environment with lots of people that support it with love, time, and money. Hope you have or intend to visit it in Mountain View. I trust I have your own financial support and trust you are a member there, too.

PDP-6 questions

by aek＠bitsavers.org

1) Are there any complete PDP-6s anywhere at all? There are none known to exist 2) Does the Computer History Museum in Mountain View have any PDP-6 artifacts? CHM has the Fast Memory chassis from the Stanford PDP-6 3) Are the stories about the Boston Computer Museum receiving a complete PDP-6 and then chopping it up to sell as gifts truth or urban legend? Ken Sumerall and I worked on putting this rumor to bed about six months ago. There are no records of BCM ever receiving the PDP-6 >from Stanford. As best as we were able to determine, the Stanford PDP-6 that was shown at DECUS for the 10th anniversary of the 36 bit product line was sent somewhere within DEC, it was NEVER sent to BCM. When Compaq donated their museum holdings to the Computer Museum History Center the Fast Memory chassis was sent. There is no evidence of any other part of the system (or a rumored additional PDP-1) surviving. It is unknown what happened to the rest of the PDP-6. We do know that we don't have it.

The guy who gave them to me related that the PDP-6 had been decommisioned circa early 80's (replaced with a FOONLY - that ought to narrow it down for you!), and he was keeping KS10's and Massbus disk and tapes drive running in his house through most of the 90's :-). I'm not sure why I'm making any attempt at obfuscating this guy's identity, I gave away so many clues above that it's obvious who it is by now!

Scitex NuBus card ID?

by bear＠typewritten.org

I just picked up a Scitex NuBus card at surplus a couple days ago. Anybody have any guesses what it is? The only connector on the card is the DIN96 NuBus connector. There are two sets of empty pads for 96-pin connectors (4 rows of 24 pads). Major chips include a Cypress CY7C342 EPLD, 40 MHz Motorola XC96002 DSP, and a custom LSI QFP marked "COLOR-SCITEX". There are a fair number of RAM devices, too, including MT5C1008 20ns 128Kx8 SRAM in one group of 8 and one group of 5, MT42C8256 70ns 256Kx8 DRAM in one group of 8, and four CY7C199 35ns 32Kx8 SRAM chips. Silkscreen marks include SCITEX, "S.C.N. II", "ZEN", "PS QUAD", and "QUAD CS". Stickers include "NURIT" and "VS500048/ 5". Guesses? The only Scitex card for Macintosh I can even verify exists is the ResoLUT, which accelerates color space translations. Not sure though if that's what I have. Any ideas? ok bear

PDP-6 questions

by sethm＠loomcom.com

I'm hoping to start a thread that might answer some questions about the PDP-6 that I've so far been unable to get resolved through Google or other means. This is all mostly spurred on by finally getting around to reading Steven Levy's "Hackers" after 23 years, and reading about the role the PDP-6 played in the early Hacker culture around MIT's Tech Square and Stanford's SAIL. It seems like the PDP-6 is one of the least well preserved of DEC's systems, maybe even the "Holy Grail" (at least to some folks). Without further ado, the questions: 1) Are there any complete PDP-6s anywhere at all? 2) Does the Computer History Museum in Mountain View have any PDP-6 artifacts? 3) Are the stories about the Boston Computer Museum receiving a complete PDP-6 and then chopping it up to sell as gifts truth or urban legend? 4) Does any PDP-6 software still exist, especially PDP-6 ITS ? (I haven't found any on Bitsavers, so I'm guessing the answer is "no") 5) Does anyone have any PDP-6 stories they'd like to share with the group? I'm hoping #5 spurs on some good discussion. -Seth

I find that simply bigger (more bits) often is nice thinking but I always do the "whatif" in instruction set and the like. When it comes to building from raw ttl I find myself specualting on longer words with multiple address schemes or something simple like PDP8 but say 16bits.

Cost Of Technology

by Billy.Pettit＠wdc.com

Recently, I tried to make a point about the cost of rolling products being a detriment to product change. I was more optimistic than I thought. Here's something from today's EETimes on the costs of innovation. I was way low. Even disk drive vendors figure $30-50 million to bring out a new drive. Change is done to survive, not to satisfy some marketing whim. Billy Quote from: http://www.eetimes.com/news/latest/showArticle.jhtml?articleID=198701495 In the new IC world order, fewer integrated device manufacturers (IDMs) can afford to build fabs, while only an elite group may be able to develop leading-edge IC designs over time. At the 45-nm node, a new 300-mm fab costs about $3 billion, process technology R&D runs $2.4 billion and a "mask set" is up to $9 million, Synopsys said. Test costs, meanwhile, continue to be flat. IC design costs range between $20 million and $50 million, the EDA company estimated. And there's a new problem on the block: process variation. Identified as one of the new "pressure points" at the 45-nm node, variation is becoming one of the root causes of chip failures. Much of the data is uncertain for the 32-nm node and beyond, but some say that by then, a new 300-mm fab could go for $10 billion, as process R&D costs reach $3 billion and design costs $75 million.

IMI disk drive on Cromemco

by dm561＠torfree.net

------------Original Message: Date: Sun, 01 Apr 2007 13:05:51 -0700 From: "Chuck Guzis" <cclist at sydex.com> Subject: Re: IMI disk drive on Cromemco I don't know if this applies to the 7700, but I do recall that the 5000 was somewhat finicky about being level. IIRC, if one inclines the drive so that the positioner is working against gravity, you'll get seek failures. Cheers, Chuck -----------Reply: Good point, although that applies to most of the old drives (especially those with a linear positioner); installation guides usually specifically disallowed any orientation like that. And of course any old drive with potentially slightly worn parts should always be used in the same orientation and given lots of warm-up time before writing to it. While we're taking about the 5000, the 5MB 5007 drive's index sensor often caused problems. It used a poorly mounted reflective optical sensor which could easily move; also, dust would accumulate in the index disk holes and on the reflective surface. mike

I am looking to sell some of it off. I figured that I would give the newsgroup members first dibs on it, then I will go to eBay. I have multiple BA35x towers (tan and blue) with the fans, personality modules, and power supply units, some of them even have the complete "skins" with the doors and stands. If anyone wants them, I have a bunch of 4 GB tan and 9GB blue SBBs available. Also I have SCSI cables of varying lengths and connector types. All of this is coming from my personal collection of pieces and parts and all parts are known to be in working order and in good condition. I can sell some individual items off as parts, but I would like to sell a couple towers as whole packages. Shipping can be negotitated if outside the US, although I am told that there are massive amounts of fees if shipping is outside the US so it may not be worth it. I am in the Milwaukee, WI area so if you are near me local pickup can be arranged. Please email ajschroeder at no-spamhotmail.com (remove no-spam first) for a complete list of parts. Thanks, AJ Schroeder

rs232 capture?

by cleng＠classicad.cz

Dear Brad, I remembered my old program ASDAT. What is ASDAT? It is a DOS tool for capturing and examining captures for capturing and examining data communication on RS232 line. It works on any DOS computer which has 2 serial ports. Using special probe (two 25-pin CANON male/female connectors + two cables connecting probe to serial ports) it captures data + modem signals including exact time information (resolution is 0.05ms). The speed of communication can be up to 19200Bd. Data are stored in the buffer (size is 8kB characters). Data can be saved to disk file after capturing. Data are showed during capture and can be examined after capture ends. There is also possibility of triggering - if you are looking for some special sequence of data on communication line. There is also way to export data from captured file (both directions together or separately). If you are interested in ASDAT I can send you a demo (i.e. ASDAT without ability to capture + some captured files) to try the user interface. I can send you also full version free of charge if you are able to make the probe yourself (BTW 15 years ago ASDAT was being sold for about 5000 CZK - about 250 USD). There was also some other development in ASDAT (new version was written for 32-bit DOS environment): - bigger (nearly unlimited) data buffer - baud rate up to 115200Bd - continuous data capturing to file etc. As far as I can remember the new version was finished but never distributed. ASDAT was never moved to Windows. Regards Cestmir Lengal ClassiCAD, Zlin Czech Republic cleng at classicad.cz

HP 2116 on ebay

by MGemeny＠pgcps.org

Making sense of the history of this processor was what started me on quite a research project today. It really looks like it became the IOP when the system was upgraded to F and if it was part of the system at retirement, that system was never upgraded to Access. It could have originally been a TSB A, but perhaps more likely started as the Main processor of a TSB B. It could have started life as the main of a C but more likely an A or B than a C. I just seems to me to be too big to have started as an A, and too old to have started as a C. If it were to have been a TSB B Main processor, it would not make much sense to purchase a newer processor to upgrade the system to a C (I don?t think C needed the floating point instructions). But then an upgrade from B, C or C? to F would have purchased a new CPU for use as the main (because F needed the floating point micro-code in the main), repurposed the old main to become the new IOP, and retired the old IOP. An upgrade to Access would have retired this processor before the system was retired and the IO cards would have been repurposed in yet another new processor (Access needed both floating point micro-code in the main and IOP micro-code in the IOP.) So, it ended it?s life as an IOP of a C? or F (most likely F). It started it?s life as an A or the Main of a B or C (most likely the Main of a B). All just my best guess from a day?s research. YMMV If anyone is going to ask the seller a question, it would be cool to find out where the system was once installed. Thanks. Hope this helps, Mike Gemeny

Converting .TD0 to .IMD / new utility

by dave06a＠dunfield.com

I've been converting some of the .TD0 image files that various people have sent to me into .IMD format using the tried and true "write it to a disk with Teledisk, and read it back in with Imagedisk" technique. This works, but gets tedious as you need to keep starting/exiting Teledisk and ImageDisk, remember which file you are working on over the time it takes to read/write the disk, and worst of all, write down the comment record from the Teledisk screen and manually enter it into ImageDisk when creating the disk. Got tiring rather quickly... So I wrote a new utility which might be handy to anyone else wishing to convert images: TD2IMD automates much of the process of converting Teledisk .TD0 images into Imagedisk .IMD format. It builds a list of all .TD0 files specified (you can use '*' so "TD2IMD *" does all .TD0 files in the current directory), then launches Teledisk and Imagedisk in turn allowng you to write/read the disk. With a single keystroke TD2IMD will enter the filename into Teledisk, then capture the comment record displayed on the screen and place it in an empty .IMD file of the same name. After you finish with Teledisk, it automatically launches Imagedisk, and also with a single-keystroke enters the filename. Imagedisk reads the comment from the empty .IMD file, lets you edit it if you wish, then reads the disk into the file. Goes MUCH faster! TD2IMD is available on my site, go to the software page, then pick "Teledisk", and look for TD2IMD on the subpage.

looking for VMS installation CDROM

by vax9000＠gmail.com

Well, I do not want to boot the installed system; I only want the process of installing. I guess I do not need a hobbyst license for this purpose. If so, would somebody sell me his un-used VMS CDROM? Any version is file. Price should be less than the official copy. Please contact me. Thank you! vax, 9000

IMI disk drive on Cromemco

by dm561＠torfree.net

------------------Original Message Date: Sat, 31 Mar 2007 21:02:51 -0400 From: info <info at harrells.net> Subject: IMI disk drive on Cromemco I have a Cromemco system that came with a IMI model 7700 Hard Drive. The drive was working when I got it but was having read errors. I begun backup up the files and planned on reformatting. I was able to back up the files I need but head a thump like something hit the drive of the drive. This is a 10" 5 meg drive with a plastic clear top. The drive then began to fail so I power it off and looked around as much as I could through the top. I power it back up and now the drive will begun ready. The heads look like they never go through the headload process but I can't be sure. If I move the unit I can see that the head actuator lets the heads float freely in and out.. I have measured all the power supply voltages going to the drive and they are good. I don't think it was a head crash as I don't see signs on the platters as much as I can see through the plastic. The top does look like it can be remove but I don't have a clean room I'm holding off until that is the last resort. I worked on CDC drives so this looks like one only smaller and without the little brush that would sweep the drives before the heads loaded. I don't have a manual so I'm limited to what I can do. I have a few questions if anyone can help with. The head lock does disengage when power is applied. Does the drive need to come up to speed before voltage is applied to the actuator? Does anyone know where I can find more out on this drive Should I get ready to make two wall clocks out of the platters? ----------------Reply: I think Herb Johnson will be able to supply you with a service manual: http://retrotechnology.com/herbs_stuff/d_crom.html (7710 IMI 7700 hard disk, 023-6027, January 1982, 100 pp.) I have one of these drives but it hasn't been powered up for at least 20 years, so I doubt that it's still good; they weren't too reliable even then. There was also a 7720 (22MB) version of this drive; they were superseded by the 5000 (5"FH) IMI drives before Cromemco finally went to ST-506. I also have the 7000 installation manual, but it only covers connectors, switches and schematics for the power supply. Get ready to make those clocks, but check it out a little more first... Good luck! mike

11/45 - unjustified progress

by jwest＠classiccmp.org

Well, I dug in to the prints for the RL02 and wrote up notes for myself on all the signals feeding the fault lamp and exactly what pins of what chips they were on (E1 and E2 of the drive logic board). Went downstairs and pushed the BA11-K back into the rack (I had it out to check the ACLO & DCLO signals). I pulled out the RL02 and lifted the logic board and got my notes ready. Instead of a logic probe I decided to use a logic clip. Easier & quicker in this case because I knew just what pins to look at on which chips, and all the signals of interest were on two adjacent chips. I powered up everything including the RX02. When I hit load, the drive spun up and came ready. No fault at all. The RL02 and RX02 both boot & work fine. I've never been quite so disappointed that a system worked, because I know I did nothing to fix it. I tried to recreate the problem all afternoon - with the machine cold, or with it running the instruction set excerciser for hours, no hiccups. The odd part is, the "RL02 faulting upon spinup IFF the RX02 is powered on" WAS completely reproducable, and it never once failed to fail. It failed absolutely 100% of the time for the past few weeks. Not only if it was on when the RL02 spinup was attempted, but if the RX02 was off and the RL02 spun up successfully - the moment you would apply power to the RX02 the RL02 would immediately fault. Now I can't get it to fail, and all I did between times was extend the BA11-K, hook up a probe and look at a few test points, then put it back. Perhaps it is cables. I'll be trying again tomorrow to reproduce the problem and hope it reoccurs :\ Jay

Intellec 4

by gkaufman＠the-planet.org

I was given an Intellec 4, but unfortunately no documentation. Also included was a smaller PCB intel 05-0436-000 which also includes American Optical P/N 11761-450. The board is about 4.5 x 5" with a 44 pin edge connector at one end, a 40 pin socket connector, and a 50 pin IDC header at the other end. It includes the usual 4004 chipset (4004, 4201, 4001x4 and 4002x2) with date codes from '74-'78 I'd like to get the Intellec 4 back to operation, anyone have documentation they could share? Also if anyone knows anything about the American Optical board I'd appreciate information. I'm not looking to sell or Ebay the unit - any help would be so that I could enjoy the system myself, and document it for the future. It's got a s/n below 20 - just curious if anyone knows how many Intellec 4's were actually produced. I had an Intellec 4-40 back in the mid 1980's that I saved from a scrapyard and donated, but that's that last time I have seen one personally. Many thanks for any help! - Gary

Marbly Heart (Re: Looking for old computer book)

by us21090＠yahoo.com

Jay, ----- Original Message ---- I distinctly remember two of the projects. One was on the working of the heart. It was a board that tilted front to back on a triangular wedge. Routed into the board was a logical diagram of the human heart. The valves were one way metal flaps that opened by rotating on a thin metal shaft or wire. The blood was a set of marbles. When you tilted the board to the back, the marbles rolled through the valves in one direction, then when you tilted it back the other way the flaps only let the marbles go into the correct chambers. --- I remember that!!! I wanted to build it, but for any number of reasons didn't. For a long time now I remember associating the marbly heart with my ESR Dr. Nim toy, which used marbles to play the game of Nim. What I don't remember is which I came across first- Dr. Nim or the Marbly article. The idea of using marbles, tilt boards, gates, has been tucked away in my brain to some day emulate **something**.

On topic? Looking for old computer book

by paul0926＠comcast.net

I hope you don't mind me asking as this is not a tech quiestion per se, but if anyone in the world will know the answer it will be this group. I'm looking for a book that I rented from a library in 1973 or 1974 on computers. In the back of the book it has plans for building a computer out of basic components, including a telephone dial for input. The output is shown on lights and I remember there being more than a few bulbs. The "computer" probably does nothing more than add numbers. I use the book to research and write my 8th grade science paper and then I tried to build the computer for my 8th grade project but could not complete it at the time. Now that I'm older and wiser I figured I'd try again.... (mid life crisis?) I don't remember any ICs. It was pretty simple electrical components. Anyone know the title or author of this book? Thanks.

NeXT slab SCSI fault

by julesrichardsonuk＠yahoo.co.uk

Anyone know if NeXT monochrome slabs have dual SCSI buses (one internal and one external) or not? I've got one here that resolutely refuses to talk to any internal SCSI device [1], but will happily talk to (and boot from, if necessary) external devices. In fact, if anything is plugged into the internal bus at all then the system won't even boot from an external device. I've ruled out internal cabling, internal power connector, something shorting the PCB underneath, and an actual device fault - which means it's possibly a bad solder joint somewhere or a cracked PCB track. However, *if* the slabs have two separate SCSI buses then it's possible that there's a fault with the actual controller too which is knocking out the internal bus. [1] Actually it "talks" in that there seems to be some device activity, but always falls over with a (useful!) "SCSI error" message whenever there's an internal device present. I'm not too fussed as the colour slab works and this one works too (albeit hanging the drive off the external connector), plus we've already got a good mono slab at the museum. It'd just be nice to get to the bottom of what's actually broken! cheers Jules

More than a little faster, at least to my recollection. Something like 3 times as fast. 16 bit disk I/O and a CPU with nearly 4 times the transistor count of the 8088. A lot of folks who bought the original 6 MHz PC AT discovered overclocking. While you could find 8 and 9 MHz 8088/8086 systems, neither came close to a 6 MHz AT in terms of performance. And if you were adventuresome and clocked that PC AT at 12 or (I've heard it was done) 20 MHz, the gains were breathtaking--and you had a convenient place to cook lunch. One thing that IBM did that really toasted me back then was messing up on the 8237 DMA controller hookup such that memory-to-memory DMA didn't work. It could have made the whole business of extended memory use a lot simpler. Cheers, Chuck

DN10K

by pdp11＠saccade.com

>Missing cards? They just might be empty, unused slots in the >backplane. That sounds like you've got the basic compliment. As I recall from my days running a network of them, the base DN10K has four cards (Network, video, CPU and memory). Extra slots were available for an FPU, more memory (and maybe a disk controller?). The CPU should be easy to identify by the presence of a MC68010 chip. The DN10K's typically did not have their own disk drives; instead they booted (and paged!) off of a "partner" server node having the disk. The network adapters (in a plastic box that screwed onto the back) were spectacularly flaky on those machines. The DN10K's had a switching power supply with a subtle audible hissing/buzzing noise corresponding closely to the machine's activity. With experience, the power supply noise was almost as informative as a blinking-light front panel. For example, it'd make a distinctive rhythmic chirp when the network was interrupted and the paging algorithm was frantically re-trying the operation to clear the page fault. If not fixed ASAP, the screen would break apart with an ugly "PARTNER NOT FOUND" message. Between the flaky network adapters and the one-fails-they-all-die ring network topology, keeping a DN10K network running was challenging. Cheers, jp

Convex parts

by wdonzelli＠gmail.com

Today I started stripping out good parts from a Convex C240 minisupercomputer - a machine I had purchased from a scrap dealer almost ten years ago. It was a disaster of a deal - one of the rare times I feel I was screwed my a junkman. The machine turned out to be missing many parts, including processors and power units, cables were chopped, memory was swiped, plus there was mouse crap evident - yuck. For years I have been threatening the part it out, and now is the time. A few parts will end up on Ebay, the metal will go to the scrapyard, and I am keeping the boards that I have for now. I know Convex machines are not very common, but if there are others that need spares for 200 series machines*, please let me know, as the boards and (hopefully) backplane will be for sale. * A guy I know that worked at Convex said the processors should mostly interchange - although a rev level problem might pop up. -- Will

DN10K

by wdonzelli＠gmail.com

My Apollo DN10000 is finally approaching sunlight, and hopefully will not go back into my shop. I want to sell it. It is a bit of a piece of work - no drives, no OS, one side cover missing (the simple kind - the flip up types are still there). Grimy as hell. A little surface corrosion. Maybe some missing cards. Missing cards? They just might be empty, unused slots in the backplane. I *think* the processor is there. The graphics card is there, as is the I/O and memory module. The cards are not really labeled, so I made some guesses. If there are others that are more familiar, please contact me. Offers entertained off list. It is located in NY (10512), and I really do not want to ship it, but there is a very good chance I can deliver late April/early May along my roadtrip, hitting Indianapolis, Boulder, Phoenix, LA, the Bay Area, and many points between. -- Will

Looking for old computer book

by fire＠dls.net

No. He is correct. Book was orange. Used futura font on cover. Had computer in name. I built and still have computer for my 6th grade project. Used telephone dial as input. Had to substitute different transistors. Had 10 flip-flops, each with a flash light bulb next to them, and a complementar bulb which I mounted in board at top of project. It could add, or subtract, or toggle. I made this modification by using a very cool rotary switch. Hardest part of project, other than my two failed rectifiers (OK, so I got it wrong, I was 11 or 12) was de-bouncing the telephone dial. My dad had a friend who was an electrical engineer who designed a lot of the electronics for Lowrey organs who helped (told me) where to change values for resistors, capacitors, and substitute in less expensive, newer transistors in flip-flops. Each flip flop was two half adders. While I am not disputing the existence or similarity of the magazine article, heck, for all I remember the author might have said, that this book is based on article he read or wrote, but this book definitely existed.

I have seen a case where plugging in an external CD drive, with passive terminator, but *leaving that drive turned off*, allows the system to run normally from the internal drive, where it would generate SCSI errors without the external drive in place. I didn't have a SCSI terminator in 50-pin mini D to plug into the external connector, but if I'd had one I would have tried it. I'd recommend trying SCSI cable to external terminator, or cable to unpowered external drive with passive terminator, and see whether that allows the internal to work. If that's productive, I'd play with the termination on the internal drive. One other possibility is a bent pin on the internal drive or on the connector, but I assume you checked for that. >It'd just be nice to get to the bottom of what's >actually broken! Absolutely.

aclo dclo (11/45) flustered-ness

by jwest＠ezwind.net

I've been looking at various documentation and have come up lacking in understanding. Can some one clue me in on the source, behaviour, and routing of the ACLO DCLO signals on the 11/45 - with expansion boxes? In my digging in the documentation I seem to be finding contradictions between various printed sources and advice from people as well. Likely they are all right and I just don't "get it". >From what I can gather, it appears that ACLO originates in the H742 power supply. Actually, it appears that both the upper and lower H742's produce ACLO and DCLO. I think Tony was saying that ACLO and DCLO on the lower H742 shouldn't be used because they are referenced to -15v instead of ground. But >from what I can gather, the only signals on the lower H742 which should not be used because of the 15v to ground change, are LTC and +8v. The lower H742 produces both ACLO and DCLO, and does route them out for use in several places. It appears that ACLO originates only in the power supply, and both the cpu and cards on the unibus monitor it to know if "death is coming". I would imagine that the cpu uses it to trap to a powerfail routine, and peripheral interfaces use it to do things like an emergency head unload on a disc drive, etc. So, what about when the unibus has been extended into an expansion box like the KB11-F with a DD11-DK, which has it's own supplies and thus it's own ACLO? Is the ACLO failure in the external expansion box given to the cpu chassis box and vice versa or are they entirely separate? DCLO also confuses me. Some things I read (and advice from some people) indicate it originates in the power supplies, and other devices only monitor that signal. However, the unibus interfacing manual states clearly that ANY device on the unibus can assert the DCLO signal. This would mean not just the power supply, but a controller like an RX02 interface (M8256) could tell the rest of the system "hey, I'm losing power". This gets back to my "RL02 faulting upon spinup only if the RX02 is turned on" problem. Tony suggested checking ACLO and/or DCLO. Note that my RL02 and RX02 controllers are in the expansion BA11-K, not the cpu box. To do this, I need to know exactly what pins to look at on the backplane. I figured I could track this down myself, but in going through all the documentation I am left very unclear as to exactly where the ACLO & DCLO signals go after they hit the power distribution board (J2-J10 I think it is) at the top of the system unit backplane. Since it is a unibus signal, I would think it would enter the DD11-K in the expansion box at the "unibus in" (slot 1AB). I would also guess that since (apparently) SPC cards are capable of monitoring ACLO/DCLO (and perhaps asserting DCLO? See above?) that those two signals would be wire wrapped from somewhere on 1AB to each of the SPC slots (C-F). Some documentation showed ACLO and DCLO on row C (some docs show only one of those is present) of an SPC slot. If that is the case, should I not see some wire wrapping on my DD11-K that shows ACLO/DCLO (supposedly on B01F1 and B01F2) getting wrapped to somewhere on row C, and daisychaining to all the SPC slots on that same pin so they can monitor it? I do not see that wire wrap on the DD11-DK. So someone could just tell me what pin to check, to see if ACLO or DCLO is acting funny around my RX02 controller. But I'd really prefer to understand the bigger picture with it as to all places that originate these two signals, what devices can assert them, and most importantly, how those two signals are routed exactly from power supply to the cpu, to the expansion box (which has it's own ACLO/DCLO), all the way to the final M9312. Then not only could I take the measurement, but better understand what I'm seeing. Any education is most appreciated! Jay West

VCF Southwest?

by sellam＠vintagetech.com

I'm considering the launching of a VCF Southwest event, but I'd need a local coordinator in that region to help with the planning and such. The ideal location for the event would be Austin. Is anyone interested in being the VCF Southwest regional coordinator? If so, please contact me directly.

NeXTstep: cloning a drive

by Billy.Pettit＠wdc.com

Jules Richardson wrote: Possibly there was a firmware "feature" in the "smaller" drive which meant the full drive capacity wasn't being utilised, but that seems like a pretty major flaw in the days when a few MB here and there was precious. If not then why someone / something (the NeXTstep installer, presumably) would format the drive below total capacity, I don't know. cheers Jules Billy responds: Actually this was a very common thing (formatting a drive below rated capacity). There are several reasons why you might want to do this. 1. One vendor is already qualified with a certain track count. The next vendor has to match that track count or else a driver has to be modified by the system provider. Easier (and cheaper) to force the disk vendor to compensate. 2. A previous capacity point has been obsoleted, but the vendor has committed to supply drives and spares for X many years. So a new drive is downgraded to match the old drive, even if means wasting some disk area. Believe it or not, this is usually cheaper too since the new drive is further down the cost curve. 3. Performance increase. By only using the outer cylinders, you get a drive that has more data per track so fewer seeks. And you are only using a portion of the surface so the seeks are shorter, hence faster. I remember a couple of times that end users discovered this and would deliberately damage drives to get warranty replacements. The replacement drives could give 30-50% performance improvement. (One Special case turned a 700MB SCSI drive into a 350MB drive. It really screamed through the benchmarks.) Billy

NeXTstep: cloning a drive

by julesrichardsonuk＠yahoo.co.uk

Does anyone happen to know where I can find a "whole disk" device file within NeXTstep? I was going to clone the OS drive of a mono Slab onto another (identical model) hard disk, figuring I'd just 'dd' the contents from one to the other. Problem is there's no obvious "whole disk" device under /dev, either for the OS drive or the "target" drive that I'm hanging off the back of the Slab. /usr/adm/messages gives me a couple of relevant entries: <drive name> as sd0 at sc0 target 1 lun 0 <drive name> as sd1 at sc0 target 2 lun 0 ... where <drive name> is just the vendor's ID string (Seagate ST1480N) and the drive's firmware revision. Unfortunately there's no such files as the obvious /dev/sd0 or /dev/sd1. There are /dev/sd0<a..h> and /dev/sd1<a..h> files, so maybe one of those (h?) corresponds to the whole disk? (according to 'mount', /dev/sd0a is the root OS partition) I could just pull the OS drive out of the Slab and hook both drives up to a Linux box and 'dd' there - but I thought I'd take the route of minimum dismantling, and of course I assumed it'd be an easy 5 minute job :-) cheers Jules

if that is the right article on eBay, then it was in Radio-Electronics magazine if I recollect. I started the same project, but never had enough money to build it.

rs232 capture?

by brad＠heeltoe.com

anyone know of a simple RS-232 capture program for Windows 95 which will capture from 2 serial ports and give a timestamp which is reasonable, like 10ms accuracy? (I might be dreaming, I realize) I'd use DOS, but my 2nd serial port is PCMCIA. Alternately, if such a thing exists for Windows XP running on a modern PC with USB serial ports, I'm open to that also. I need to do some field data collection and I figured someone here might know of a simple program. thanks! -brad

Arcturus Computer and display system.

by RodSmallwood＠mail.ediconsulting.co.uk

Hi All Whilst sitting on the plane on the way back from Newcastle yesterday. It reminded me of a system I saw at Gatwick airport in the early 1970's. I'm pretty sure it was run by a mini computer called an 'Arcturus'. I can clearly remember the grey rack mounted box with its row of toggle switches and lamps. I was there to install a VDU (sometimes referred to as a glass teletype). The big teletype they drove it from made the whole place shake and the VDU I fitted of course did not. It drove the departure / arrival TV monitors. The way it generated the characters was curious to say the least. It had a large number of circuits which generated parts of characters. One did a vertical bar, another produced a whole circle whilst others output parts of a circle, forty-five degree bars and so on. For each character cell the component parts of the required character were selected summed and added to a TV raster. Does anybody remember the Arcturus? Rod Smallwood

Fortran Versions (was JB Passes)

by swtpc6800＠comcast.net

> How did newer versions of the language handle deprecation of the sense > switch - error, warning, ignore? I was evaluating compilers for the IBM PC in late 1982 or early 1983 and tried the original Microsoft Fortran. The error message in the manual for the read sense switch statement was somethine like "you show me the switches and I will read them." We evaluated Fortran, Pascal and C and selected C for our project. We needed a language that would support VAX VMS, VAX Unix, and the IBM PC. Michael Holley. www.swtpc.com/mholley

For what it's worth, the HP controller number for their 913xB drives is 09133-69514. For 10MByte: J6 Pins jumpers (10M, One Volume and 4XX) are all installed. I've no info on The 15Mbyte configuration. Hope that helps, Martin
