Looking for CP/M-86 for Compudata Tulip System I

by Fred.van.Kempen＠microwalt.nl

Freek, Een hele oude vriend van me, die ik al zeker 15 jaar niet heb gezien, had er een. Die mensen verzamelden ook vanalles, en ze waren heel zuinig op de spullen. Ze zouden die machine plus aanverwanten nog best eens kunnen hebben. Via telefoonboek of 0800-8008 zou je hun telnr kunnen achterhalen; ik weet het niet meer: Roeland & Maarten Tuk Schoonoord [ik meen] 92 Voorhout, ZH Groets, Fred

HP 7980S scsi 9-track

by Fred.van.Kempen＠microwalt.nl

Thanks to all who responded, both on-list and off-list. Summary: While READING, the 7980S will always default to whatever it finds on the tape currently loaded. If no format can be found (? bulk- erased tape?) it will use the setting below. While WRITING, it will use the desity as set with the CONF 46 setting. So, to fix my problem I had to set CONF46 to 1600, rather than 6250, and it worked. :) Cheers, Fred

It's less than certain. The supported densities are determined by the installed board set. There are many 88780s out there that only do 1600 and 6250. Fewer that do 800 too. I have yet to run across one that only does 1600 but it's a possible configuration; HP sold that (w/HP-IB interface) as the 7979A. For 7980s, 1600 and 6250 are standard and 800 is an option. 7980A is HP-IB, 7980S is SCSI (single-ended). There's also an "XC" option which does in-the-drive compression on 6250BPI tapes; I think this option does not coexist with the 800BPI option. BTW, a couple months ago Sun had a version of their service manual for the 88780 up at: http://sunsolve.sun.com/data/800/800-3447/pdf/doc.pdf It's missing the figures though. > Bear in mind that you'll need some fairly specialized (and > expensive -- in the $300 region) software if you want to use > that drive on any sort of PC. Last time I noticed, FreeBSD and Linux were able to make use of a SCSI interface with an attached 88780. -Frank McConnell

5150 & 720 KB FD

by robert_little_2000＠yahoo.com

Think I found the problems.... Machine #2 (the one I'm rebuilding) had its DIP's set for a single drive. After correcting that, still failed to work, so decided to check out the 720 itself... AH HA! Of course it wouldn't work. It was a dead drive. As for the purist out there who shudder at the thought of adding later components to such a classic, I should mention that I'm an astronomer. I don't have the systems as collectibles, I use them. Yup, that's right... when you're on a budget, you have to make everything work. This ol' PC is basically just going to serve as a real time clock. With CGA monitors they are good for that... Better that then have it go to the landfill (as is too often the case...)

Hi, I am the proud owner of 3 of these old (1991) terminal servers. DSRVW-YC. A01 Unfortunately, I have absoloutly no doco. I have been able to determine that the device is trying to TFTP a configuration file of some type. But I can not find any doco since Compaq desimated the Digital support sites.

VCF Gazette Volume 1 Issue 3

by vcf＠siconic.com

VCF Gazette Volume 1, Issue 3 A Newsletter for the Vintage Computer Festival October 1, 2002 Hello Vintage Computer Fans! The VCF Gazette is back again with more news about the Vintage Computer Festival. In this issue: VCF 5.0 Venue Change VCF 5.0 General Information VCF 5.0 Special Events VCF Open House Update Latest Additions to the VCF Archives VCF 5.0 Venue Change -------------------- The VCF is pleased to announce that this year's Vintage Computer Festival is being sponsored by the Computer History Museum. This sponsorship has enabled the VCF to be held at the Moffett Training & Conference Center at the Moffett Federal Airfield in Mountain View, California. The move has several advantages, including tighter integration with the tours to the Computer History Museum's Visible Storage exhibit area. Tours of the Air & Space Museum will also be available. The Computer History Museum has always shown support for the VCF in the past by exhibiting terrific artifacts from their collection in the VCF Exhibit. We greatly appreciate this new level of commitment to and support of the Vintage Computer Festival! VCF 5.0 General Information --------------------------- Vintage Computer Festival 5.0 is scheduled for October 26th and 27th. Doors open at 9:00AM each day, with talks beginning at 10:00AM and running until 2:00PM. The Exhibit and Marketplace is open from 2:00PM until 6:00PM each day. The admission to VCF 5.0 is $10 per person per day for full access to Speakers, the Exhibition and the Marketplace, or $4 per person per day for Exhibition and Marketplace access only. Kids 17 and under are admitted free of charge, and parking is free. VCF 5.0 is being held at the Moffett Training & Conference Center at Moffett Federal Airfield in Mountain View, California. Check the VCF 5.0 website for more details and directions. LODGING The VCF has reserved a room block at the County Inn in Mountain View, California, which is a short drive or walk to Moffett Field. The room rate is $69 per night for single or double occupany. Reservation information as well as information on other area hotels can be found on the VCF 5.0 Lodging page: http://www.vintage.org/2002/main/lodging.php EXHIBITORS If you wanted to an exhibit a computer from your collection, there is still time to register. To register as an exhibitor, please go to: http://www.vintage.org/2002/main/exhibit.php VENDORS The VCF still has vendor booths available. The VCF Marketplace is the best place to sell your old computer items to a targeted market. You may also sell items on consignment and leave the hassle to us. For more information on the VCF Marketplace and consignment sales, please visit: http://www.vintage.org/2002/main/vendor.php VCF 5.0 BBS The VCF has just launched a bulletin board system on the VCF 5.0 website to enable attendees to communicate with each other before the event to arrange trades, form carpools, and discuss the VCF in general. The BBS can be accessed here: http://www.vintage.org/2002/main/bbs.php FOREIGN NATIONALS Foreign nationals can disregard previous announcements about the requirement to register in advance in order to be allowed access to Moffett Federal Airfield. The confusion with the entry procedures was caused by a miscommunication. Foreign nationals will be allowed onto the base just as any United States citizen, but as is required for all persons entering the base, valid identification must be presented at the main gate. We sincerely apologize for the confusion. SPONSORS The Vintage Computer Festival gratefully thanks its sponsors, the Computer History Museum and the Alameda County Computer Resource Center. Computer History Museum http://www.computerhistory.org Alameda County Computer Resource Center http://www.accrc.org VCF 5.0 Special Events ---------------------- We are adding new features to the VCF this year to increase attendee participation. Along with the Nerd Trivia Challenge, the popular quiz game that tests your computer history knowledge, the VCF will feature the Retro-Code vintage computer coding challenge in which attendees will write games on old home computers within a limited time period at the VCF. Information on the Nerd Trivia Challenge can be found here: http://www.vintage.org/2002/main/ntc.php Information about the Retro-Code challenge is here: http://www.vintage.org/2002/main/retrocode.php COMPUTER HISTORY MUSEUM TOURS Tours of the Computer History Museum will be running throughout the exhibition hours of the VCF. Those that have not yet had the opportunity to visit the Computer History Museum's Visible Storage exhibits will certainly want to take advantage of this. For more information about the Computer History Museum, please visit their website at: http://www.computerhistory.org/ DIGIBARN EXCURSION The DigiBarn is a computer museum in a country setting (literally housed in a barn in the Santa Cruz Mountains). Bruce Damer, the curator of the DigiBarn, will be heading the excursion. A caravan will leave the VCF at approximately 2:30pm on Sunday and return before the close of VCF 5.0. More information about the DigiBarn can be found on their website: http://www.digibarn.com/ APL BAY AREA USERS' GROUP MEETING The VCF is hosting a meeting of the APL Bay Area Users' Group (The Northern California SIGAPL of the ACM) at VCF 5.0 in conjunction with the lecture that will be given by Zbigniew Stachniak. Zbigniew will be discussing an early portable personal computer, the MCM/70, which ran APL. The meeting will take place at 3:00pm on Saturday, October 26, in the speaker hall. For more information on the APL BAUG, visit their website: http://www.acm.org/sigapl Stay tuned for more VCF event updates! VCF Open House Update --------------------- The first VCF Open House is still in the works. We had promised to have the VCF Archives ready for display by now but progress has been slower than hoped. Still, progress is being made. Most of the material needed to build out the floor has been acquired. Construction on the floor will begin in October. Once it's complete, artifacts will be selected and exhibits will be assembled throughout the Fall, with an anticipated museum opening sometime in late November or early December. Again, the VCF would like to thank the Alameda County Computer Resource Center for generously providing space for the VCF to store our archives. The Alameda County Computer Resource Center is the largest non-profit computer recycling operation on the west coast of the United States. You may visit them on the web at: http://www.accrc.org/ Better yet, visit them in person and volunteer your time to help put computers into the hands of deserving kids, schools and organizations world-wide. Volunteering details can be found the ACCRC website. Latest Additions to the VCF Archives ------------------------------------ The VCF has continued to acquire new (or rather "old") artifacts since our last update. One of the most exciting is our acquisition of a Digital Computer Controls D-116 minicomputer. The DCC D-116 is roughly a clone of the Data General Nova 830. We have also acquired a Linus WriteTop. The Linus WriteTop was the first pen-based computer, manufactured in 1986. The computer did not meet with much success, mainly because the hand-writing recognition was not perfect (but then, it still isn't 16 years later ;) That wraps it up for this issue of the VCF Gazette! Until next time... Best regards, Sellam Ismail Producer Vintage Computer Festival http://www.vintage.org/ The Vintage Computer Festival is a celebration of computers and their history. The VCF Gazette goes out to anyone who subscribed to the VCF mailing list, and is intended to keep those interested in the VCF informed of the latest VCF events and happenings. The VCF Gazette is guaranteed to be published in a somewhat irregular manner, though we will try to maintain a quarterly schedule. If you would like to be removed from the VCF mailing list, and therefore not receive any more issues of the VCF Gazette, visit the following web page: http://www.vintage.org/remove.php ;) -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Looking for CP/M-86 for Compudata Tulip System I

by f.heite＠hccnet.nl

Hello, Someone out there who has the CP/M-86 software for the Dutch-made Compudata Tulip System I? It's an 8086-machine that is hardly IBM-compatible (as it was introduced before the IBM PC). The BIOS is completely different from IBM-PC-standards. Under Tulip's MS-DOS (which was also available when buying this machine) it has a whopping TPA of about 900 KB, as the video RAM is somewhere at the top of the 1 megabyte memory, and there are no expansion cards with their own BIOSses. The 5,25 inch diskettes could store ca. 800 KB each. Thanks, Freek Heite

The QBus equivalent of an RK11 is an RKV11-D, which is a single quad board, controlling up to eight RK05's. They were moderately common on larger 11/03 and some 11/23 systems. The RK06 and RK07 use an RK611 controller, which is a large multi-board unit occupying two system units, usually in an expansion box. There's no QBus equivalent that I know of. Emulex did make QBus boards that emulated an RK611, or more accurately, emulated the whole RK711 subsystem using a QBus SC02 controller and an SMD drive, but you couldn't connect a real RK06/7 to one of those. The OS could be RT or RSX, possibly RSTS or something more unusual like MUMPS. Even 7th Edition Unix has an RK driver. I think RT-11 or RSX-11 would be most likely, though. -- Pete Peter Turnbull Network Manager University of York

RK05 or RK07

Hi, I've been asked to try to get some data (to CD) from some number of RK05 and/or RK07 packs. I have an old 11/73 floating around, but I believe the RK's were only for Unibus, so the drives alone wouldn't help me. My contact is unaware of the O/S, but I resume its got to be RT or RSX. (?) Is there anyone in or near NYC that can handle these? If you can get the files to a tape via COPY, I think we can take it from there.

Searching for eBay seller "Mobybids"

by tony.eros＠machm.org

Has anyone on the list dealt with the eBay seller known as "Mobybids"? He/she recently won a couple of auctions for some old DEC documentation. In particular, a teacher's guide ( I have the workbook, but not this) for the DEC Computer Lab really caught my eye, but I got outbid. I've tried sending a couple of eBay "Question from eBay member" notes to Mobybids, but got no response. I should probably take the hint and just stop trying, but I thought I'd run it by the list anyway, just in case. -- Tony

Attention 1802 fans...

by glenslick＠hotmail.com

One thing I really regret is that I bought all of the parts to build an Elf back when the Popular Electronics articles came out (I was only twelve at the time) but never actually finished building it because someone my father worked with gave me a KIM-1 that he no longer needed and it was more interesting to use an already working computer than try to build one. I kept all of the parts and the articles until I returned home from college and then, gasp, threw them out. I really wish I still had them now so I could build the Elf that I never finished. I guess I should just acquire some 1802 chips and finish the job now. I also regret trading in the KIM-1 along with a 8KB ram board and a SWTP terminal that I built from a kit a year or two later for credit toward an Apple II+ when they were brand new.

11/44 rescue complete

A rescue not without it's glitches and travails - from the fact that it took somewhere plus-or-minus a year to get the equipment released from the Large Company where it had been mothballed - only the dedication of it's former sysop kept it from the Dumpster of Death, to several hurdles that had to be danced around in actually effecting rescue process. Thanks to Sellam for orginally brining it to my attention. Thanks to Marvin who, on very short notice, drove over 400 miles round trip to pick up the System, and whose van subsequently broke down and required towing to a service center, with the computers and software and manuals still loaded. Thanks also to two non-listmembers who went out of thier way to help us - one of whom worked for the aforementioned service center, where the Poor Van got locked inside for the evening, even though Marv requested that it be left out so we could transload it... I now have 2 11/44s set up as mirrored systems - if one failed the other could be switched over 'easily' - 2 SCSI HDs of unknown capacity (they're full-height and look like Seagates from the front - 1 RL02 - and an 11/23 used as a serial line concentrator. The system runs RSX-11M. A Blue Wall came with it, and about 20 diskpacks. Perhaps this coming weekend I will find the time to power it up and see how it's journey of years of storage and a thousand miles in vans and pickup trucks has treated it. Here's hoping it's still Happy!! Cheers and thanks to all who helped! John

CPMUG Disk

by RCini＠congressfinancial.com

Hello, all: I'm preparing another release of the Altair32 Emulator and I wanted to start building different program diskettes. I remember sometime in the past someone on the list provided me with a file listing from the old CPMUG Archive and also provided a few ZIP files >from the archive. Unfortunately, I can't find that person's email address. If someone has this archive (or a pointer to it), please contact me off-list. Thanks. Rich

IBM PC 5150 and 720KB Floppy Drive

by robert_little_2000＠yahoo.com

Got a question... I have just received an original IBM PC; actually, 2 of them (one had to be parted out). I still haven't checked the BIOS date, but the machine does have an origianl Intel 8088 and the power supply appears to be the original design. Here is the crux of the problem... I want to refit the machine with a 720 KB 3 1/2" drive. This was a fairly easy mod that we used to perform on XT's, but it seems to have problems finding the drive. Anybody out there have any experience with this? Robert __________________________________________________ Do you Yahoo!? New DSL Internet Access from SBC & Yahoo! http://sbc.yahoo.com

Altair-what do I do first

by kapteynr＠cboe.com

Good move -- don't plug it in yet. The biggest danger is that the electrolytic capacitors have depolarized. In that case, they could heat up and explode when you turn it it on. Search Google for "reforming electrolytic capacitors" and you get a lot of links. In any case, detach everything from the power supply and check it out first. Unfortunately, Altairs have no connectors for this, so you will have to desolder the wires. Some suggest powering it up slowly on a variable transformer, but I have not tried that. After checking out the power supply voltages, unplug all of the cards and power up the front panel only. Then do the same for the CPU, etc. -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]On Behalf Of Ron Hudson Sent: Tuesday, September 24, 2002 8:51 AM To: Classic Computers Subject: Altair-what do I do first I have just been offered an altair computer, it's been sitting in the back of a garage, unused for some time.

Altair-what do I do first

by bshannon＠tiac.net

Thanks for catching my typo Joe. The MTBF (mean time between failures) is greatly REDUCED by unsoldering chips, often very dramatically so. Ever notice the soldering specifications for TTL devices, like 300 degrees C for not more than 10 seconds? This limitation is given for the parts to meet their rated MTBF, not because 300 degrees C for 11 seconds will destroy the parts right away. Resolder the parts, and you may be throwing away well over half their service life. Clearly not a professional way to restore a machine. For some repairs, we have no other option, but melting solder is a last resort.

But I doubt many people on this list even truely understand what MTBF is.

With a modern version of DOS, it will either work outright or you might need a DRIVEPARM statement to let DOS know it's a 720k.

Eulogy for Bob Wallace by Dan Gillmor

by vcf＠siconic.com

Dan Gillmor wrote of Bob Wallace in his September 28 column in the San Jose Mercury: Bob Wallace, personal-computer software pioneer, philanthropist and activist, died last week in San Rafael. He had a too-short life, but accomplished more than most. Wallace was 53 when he died, apparently of natural causes, according to the Marin County coroner's preliminary report. He was one of the first Microsoft employees, but left in the early 1980s to start his own company, Quicksoft, which sold a popular word processor, PC-Write. He may be best known for his early contributions to the genre of software that became called "shareware"-- a marketing method in which people would buy diskettes with free-to-try software on them, or download it, and then let them buy it if they liked it. He had qualms about the commercial software industry, and once told the New York Times, "My philosophy is that I want to make a living, not a killing." Wallace worked, in college and afterward, with some of the industry's leading lights. He joined Microsoft in 1978. Wallace's interests ranged beyond the computing world. He was also known among drug-policy reformers, and funded medical and social research about psychedelic drugs. Wallace had many admirers, including his former employers at Microsoft and technology luminaries in Silicon Valley. "I remeber Bob as a gentle soul who was soft-spoken, but creative, persistent and meticulous in his programming and thinking," Microsoft co-founder Paul Allen told the Times this week. Rest in peace. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
