Booting a VAXstation 4000 VLC off the hobbyist boot CD-ROM

by KVanMersbergen＠RandMcNally.com

David- It might be the drive itself, I'd try a 1X drive if you have one. -----Original Message----- From: David Betz [mailto:dbetz@xlisper.mv.com] Sent: Wednesday, July 14, 2004 4:00 PM To: On-Topic and Off-Topic Posts Subject: Booting a VAXstation 4000 VLC off the hobbyist boot CD-ROM I have my VAXstation 4000 VLC running to the ">>>" prompt and would like to boot the hobbyist CD-ROM to install VMS on the hard drive but I'm having trouble getting the CD-ROM to boot. If I type 'boot dka400' at the prompt, the CD-ROM spins up and I get the text "-DKA400" displayed on the console but then I get the ">>>" prompt again. Can anyone tell me why that would happen? I'm using a NEC CDR-1910A SCSI CD-ROM drive set to SCSI ID 4. *************************************************************** This E-mail is confidential.

FW: RK05 question

by GOOI＠oce.nl

Hmm. So in your mind experiment you keep the 12 sector pulses and the track pulse, and deliver the track pulse with 16 sector pulses to the hardware of the drive logic. Using the 12 sector pulses will probably produce a more stable 16 sector pulse signal as the PLL is kept in lock in shorter intervals. But what would the PLL circuit do when it gets 12 sector pulses (that is fine) *_and_* at some odd moment the extra track pulse ...? I was thinking of *only* the track pulse and get the PLL locked on that pulse only, assuming that the stability of the PLL is sufficient for one revolution. From the N divider is would be easy to get the sector pulses. So, I cover all the sector slits on the hub of the disk. But as you said (I did not know that part and did not check on an RK05 pack I have at home), the track pulse is not halfway two sectors. Some separate binary comparator could check the N divider outputs and then you simply set a binary number to the comparator when it should give the track pulse. - Henk. > -----Original Message----- > From: cctalk-bounces(a)classiccmp.org > [mailto:cctalk-bounces@classiccmp.org]On Behalf Of Paul Koning > Sent: dinsdag 13 juli 2004 16:38 > To: cctalk(a)classiccmp.org > Subject: RE: FW: RK05 question > > > >>>>> "Gooijen" == Gooijen H <Gooijen> writes: > > Gooijen> Isn't the track index pulse == the one pulse that is fed to > Gooijen> the PLL phase comparator?

Anyone have/know of Persci drives, parts

by Watzman＠neo.rr.com

I need some Persci 8" drives (model 270 or 277) and/or parts to repair them for some systems. The part that I need most is the very large circuit board on the right side of the drive. Anyone know of a source? [I'm sure that there are thousands of them in various landfills, but that won't help me ......] Thanks, Barry Watzman Watzman(a)neo.rr.com

PDP11/73 power-up codes

by runtime＠wzrd.com

I found EK-KDJ1A-UG-001 "KDJ11-A CPU Module User's Guide," which might help, because unless my memory fails me, the KDJ = 11/73. I didn't immediately find power-up codes in it -- probably because something like MXV11-B2 or other ROM set issues the codes. If I can find an MXV11 doc, I'll post a message. I used to have one. Contact me if you want the KDJ11 manual. runtime(a)wzrd.com DM

front panel toggle & paddle switches?

Does anyone have a list of the part numbers and brands of the various toggle and paddle switches used on the various computers? Or better yet, close up pictures of the switches? I find lots of surplus equipment with nice toggle and paddle switches and I keep wondering if they're the same as those used on any of the collectible computers and if I should pull the switches and save them.

Document request

by Watzman＠neo.rr.com

It turns out that about 3 years after they went out of business, a 12-volume "Encyclopedia" of Processor Technology data was published by Stan Sokolow called the "Encyclopedia Processor Technica", aka "EPT". [There is some question as to whether volume 12 was ever actually published.] I'm trying to find this and get it converted to PDF files. Bob Stek has loaned me volume 9 to scan (covers the Helios Disk System), which will soon be on Howard's site (http://www.hartetechnologies.com/manuals/). Does anyone have any of the other volumes? This is a rare document, there were probably no more than a couple of hundred printed, if even that many, and that was over 20 years ago. If you have this and are willing to loan it out for scanning, or scan it yourself (each volume is about 300+ pages), please contact me (Watzman(a)neo.rr.com). Still looking for a number of other manuals also, plus anything that isn't in the library (these below have specific requests): * AB Digital Design Labs B810 RAM * CCS 2820 CPU Board Manual * CCS 2-Serial/2-Parallel Card Manual * Cromemco [2716] 32K Bytesaver * Cromemco 64KZ Manual * DIGITEX Systems Manuals. * DUAL Systems Manuals not listed. * Ithaca Audio 1010 CPU Board * NNC ("No-Name Computers") Manuals * OSM Computer Corp Z80 CPU "CPU/64K" Board * S.

RZ25-E in a VAXstation 4000 vlc?

by dbetz＠xlisper.mv.com

I have a VAXstation 4000 vlc without an internal hard disk and a spare RZ25-E drive. I had thought I could install the drive in the vlc but it seems from inspection that the vlc needs a lower profile drive. What drives are compatible with the vlc? If it won't work as an internal drive, I guess I can install the RZ25-E in an external SCSI enclosure. Should that work with the vlc?

Commodore Pet ROM trouble... EPROM Substitutes...

Sorry, me again. Mentioned TMS2532 Eproms are one of these Unobtainiums here. Looking at the Pinouts I have in my databooks there are little (minor?) Differences to the standard 2732's (besides the different Program Supply Voltage). I couldn't find much ressources online, but would it work if I made a small adapter like "illustrated" below... 2732 2532 EPROM -> SOCKET Pin(s) Pin(s) 1-17 -> 1-17 18 (E) -> 20 (PD/PGM) 19(A10)-> 19 (A10) 20(GVpp)> 21 (Vpp) 21(A11)-> 18 (A11) 22-24 -> 22-24 Please correct me, if I'm completely wrong and trying to do something impossible. 2732's would be easy to obtain, and I have some prommer-schematics and software handy.

I am afraid that computing standardised too early causing everybody to get locked into a technology that is too clunky. Microsoft's "innovation" essentially boils down to two things: a) adding useless junk to their already bloated platforms, and b) adding "essential" applications (e.g. Web, or audio) to their base platform so as to dictate the standards and eliminate competition. This strategy, although excellent for Microsoft, is to the detriment of everybody else. I have PCs running windows because I must, but I don't need the latest and greatest Microsoft offering, I am running Windows NT4.0 with Office 95 (which btw will soon be covered by the 10 year boundary :-). I will soon have to move to something more recent mainly because vendors do not support Windows NT, so I will not have the drivers to run Windows NT on my new hardware. PC hardware *is* a commodity, but never be fooled into thinking that Windows software is also a commodity. **vp

Commodore SX64 probs...

by julesrichardsonuk＠yahoo.co.uk

I've got a pair of non-working Commodore SX64's here. One machine powers up, but the floppy drive light remains lit and I can hear the drive spinning continuously, and there's a 50% grey pattern filling the screen (i.e. pixels look to be alternating white/black). Actually, there's also short run of pixels middle-bottom of the screen which aren't illuminated at all. Pressing reset has no effect. Pressing caps-lock does result in the caps-lock light illuminating, but I don't know if that's a simple circuit hardwired to the key and doesn't go via the CPU... The second machine is totally dead - no activity whatsoever. There's a *very faint* humming noise from the monitor area, typical of a display that's at least getting power though - but on the CPU side of things no chips seem to be getting remotely warm, suggesting that there's no +5V. Before I start digging deeper, does the fault with the first machine sound familiar, and are there any common PSU faults which affect these systems? Plus, anyone have schematics they could scan? Be nice to get one of them going. One keyboard is damaged (plus I only have the one original keyboard cable), so it's only really viable to have one running, but I'd like to get to the bottom of what's up with both of them... cheers, Jules

cctalk Digest, Vol 10, Issue 74

by tradde＠excite.com

Crisis Computer in San Jose has the equipment to write CE packs. They aren't going to be cheap. I'm guessing $300 to $500. They are probably the only place in the world left that has the gear to do this. Realigning 2315 heads isn't something you want to do if you don't absolutlely HAVE to, since you run the risk of making the packs that you have unreadable, if they were written on drives that are off spec. ------------------- I believe I have to consider this. I have no packs with any data on them that I need. They were all just data packs with automotive parts in inventory and such. I cleaned a pack and loaded it into my RK05 drive zero and it would not pass the read/write test. I don't remember what happened when I tried to use drive 1. I believe it failed but in a different manner. I thought if at least one drive was working I'd be Ok for awhile. I am not sure if I want to spend $300-$500 on trying to get a CE pack that may not help me if my drive is failing for some other reason than alignment. _______________________________________________ Join Excite! - http://www.excite.com The most personalized portal on the Web!

Commodore Pet ROM trouble...

by wolfgang＠eichberger.org

Thanks Pete for your fast answer. Yes it is a BASIC 4 Machine with these 4116-4 RAMs. You wrote the correct substitute for the ROM chips are Texas Instruments TMS2532 or equivalent. Is this right for all the chips I will list below? I hope the TMS2532 are easy to purchase here in Austria. Looking through my little library I found the datasheet (at least a good start) but I couldn't find a refence for substitutes - do there exist any? Are the TMS2532 fully Pin-compatible with the MOS ones? And my last question: Do I need anything special to write these chips? I'd put together a little circuit to hook on my Pc's Parallel-Port (this would be the easiest way for me). I'm already googling for information, but would be very glad of some links to schematics and software. Best regards, Wolfgang ==================================================== Ing.

Commodore Pet ROM trouble...

If it's BASIC 4 and dynamic RAM chips, it should be 4K ROM chips, and the EPROM equivalent is Texas Instruments TMS2532 or equivalent. Note that this is not the same as the more common Intel type 2732. > I'm > also a bit confused what image I should use (see > http://www.funet.fi/pub/cbm/firmware/computers/pet/index.html)... It depends on exactly what type of PET you have. But I'm not sure there's a whole set there, for the later PETs. I *think* you need: kernal-4.901465-22.bin basic-4-b000.901465-23.bin basic-4-c000.901465-20.bin basic-4-d000.901465-21.bin and possibly one other that I don't see (901465-29 or equivalent). I can't remember what's in the E000-EFFF space. The best thing to do is look at the ROMs you have, see what the numbers are, and try to match them. As far as I know, you can't mix parts of sets. -- Pete Peter Turnbull Network Manager University of York

Commodore Pet ROM trouble...

by wolfgang＠eichberger.org

Hi, a couple of days ago my Pet 2001N (the 2000 Model without the cricklet-keys) gave up :(. See http://www.portcommodore.com/commodore/pet/petfaq/models.html for reference. It's the 2nd machine from top, equipped with 32k RAM. When trying to boot it puts random characters on screen. As far as I found out this _should_ be a ROM-Problem (could be RAM too, but I hope it's ROM as I ran a Ram-Test successfully before the Pet died). I would like to try replacement ROMs before I have to use one of these replacement solutions plugging a little board into the CPU socket and providing it's own ROM and RAM. Could somebode please provide me some Info, what Eproms I could use as replacement for the original Commodore ones (Basic 4)? I'm also a bit confused what image I should use (see http://www.funet.fi/pub/cbm/firmware/computers/pet/index.html)... As you see, I have a lot of questions. Please excuse my horrible english. I'd be habby about every hint, trick etc... Best regards, Wolfgang Eichberger PS: It'd be great too, if somebody could provide me burnt roms as my only eprom-burner is for C=64. ==================================================== Ing.

Early timesharing/BBS systems

by aek＠spies.com

There were probably a lot, but I remember "Call/370", which I think was one of the first commercial ones. == I have an Auerbach report on timesharing services which I'll try to dig up, which gives short company histories for many of the early commercial services. Most of the major computer companies were offering some service by the late 60's. Part of IBM's antitrust settlement with CDC was that CDC got IBM's service bureau operation. GE timsharing stuck around for a while. Tymeshare was one of the earliest independents, bootstrapping themselves and fixing tons of bugs in the GENIE code. I also forgot to mention HPs timeshared basic and 3000 systems, also from the very early 70s ( the 3000 being HP's 'real' timesharing machine, so they said)

I did recall that some 5v DRAM's had "weird" pinouts.

The only thing I'm not sure of is the microwave oven - does the >microwave-generation-thingy depend on vacuum? Hi You see, knowledge already lost. Yes, a magnetron has a vacuum in it. It has a filament and a plate ( with cavities in it ). While the principles of these things can be found in books, much of the mechanical and physical methods used to create these things is lost. Partly because of the fact that manufactures don't tell all and partly because no one is dealing with these kinds of things. While it is claimed that the information is in books, there are some feel things that rarely seem to make it into these books. Can anyone tell me what controls the gain of a vacuum tube ( other than someone that actually worked with these )? Can anyone tell me how the grids must be placed for an electrometer preamp tube and why? While we don't need these kinds of things today, the knowledge of what makes these things work is still quite valuable. This understanding can keep us from making mistakes with other related problems. I can't say that these specific things that I've mentioned will be the most important things to remember but these are the types of tidbits that make the difference when looking into new problem areas of the future. Those that understand these things will always be in demand. Those that think they can ignore these kinds of things will wonder why things are beyond understanding. This goes for the entire range of things. You can't understand how to think about things without actually thinking about things. Dwight

Broken list reenable mechanisms

by mouse＠Rodents.Montreal.QC.CA

I'm sorry to have to bother the whole list with this. I already wrote to cctalk-owner and got no response whatever as far as I can tell; I figured I'd let myself try the list, once, in the hope someone is watching there but not at the -owner address. It seems my subscription has been "disabled due to excessive bounces". The mail saying so includes a token that I can supposedly send back to reenable things, but it doesn't work, probably because the list software (a) waited ten days after disabling before telling me anything and (b) didn't generate a newly-valid token after waiting. The last rejection (not bounce, no matter what the message thinks - I don't accept-and-bounce except under very unusual circumstances) was July 3rd (not the July 6th claimed by the message, unless later attempts came through a different host), and I got no notification until July 13th. I replied immediately and got told the token was invalid (with a note that they're good for only three days). I sent the whole mess off to cctalk-owner. Just now, a week later, I got a second notice of disablement. It included _the very same token_, despite it now being a week older. (It still doesn't work.) Today's notice of disablement and the response to my reenablement attempt are quoted below, after my signature. Does anyone know what's wrong here and whom I need to nudge to get it fixed? As I said, I've already tried cctalk-owner. (Obviously, I won't see on-list replies here; direct, or at least copy to me, would be needed for me to get it.) I can dig up copies of last week's notice and response too, if desired. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ---------------- Notice of disablement > From cctalk-bounces(a)classiccmp.org Tue Jul 20 09:45:01 2004 > Return-Path: <cctalk-bounces(a)classiccmp.org> > Received: from localhost (localhost [[UNIX: localhost]]) > by Sparkle.Rodents.Montreal.QC.CA (8.8.8/8.8.8) id JAA10201 > for mouse; Tue, 20 Jul 2004 09:45:01 -0400 (EDT) > Received: from huey.classiccmp.org (huey.classiccmp.org [209.145.140.36]) by Sparkle.Rodents.Montreal.QC.CA via TCP with SMTP id "MVtBZN.GTXL.Mnd"; 20 Jul 2004 09:44:59 -0400 (EDT, 13:44:59 GMT) > Received: from huey.classiccmp.org (localhost [127.0.0.1]) > by huey.classiccmp.org (8.12.8p1/8.12.8) with ESMTP id i6KE03bY051097 > for <mouse(a)rodents.montreal.qc.ca>; Tue, 20 Jul 2004 09:00:04 -0500 (CDT) > (envelope-from cctalk-bounces(a)classiccmp.org) > MIME-Version: 1.0 > Content-Type: text/plain; charset="us-ascii" > Content-Transfer-Encoding: 7bit > From: cctalk-request(a)classiccmp.org > To: mouse(a)rodents.montreal.qc.ca > Subject: confirm 93199cd740a4a110d65b18d1aea766bc9f292eaa > Message-ID: <mailman.0.1090332000.51096.cctalk(a)classiccmp.org> > Date: Tue, 20 Jul 2004 09:00:00 -0500 > Precedence: bulk > X-BeenThere: cctalk(a)classiccmp.org > X-Mailman-Version: 2.1.4 > List-Id: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk.classiccmp.org> > X-List-Administrivia: yes > Sender: cctalk-bounces(a)classiccmp.org > Errors-To: cctalk-bounces(a)classiccmp.org > > Your membership in the mailing list cctalk has been disabled due to > excessive bounces The last bounce received from you was dated > 06-Jul-2004.

VT52s and VT61 clearance

by wacarder＠usit.net

My new classic computer room is quickly filling up and I need to clear out some space. In my quest to find a working Dec VT52, I have acquired several dead or semi-dead ones that I don't want to spend the time to troubleshoot right now. I also have a VT61 that powers up to a flashing "block style" cursor. I have not attempted to connect it to the PDP-11/34 because I do not have my 11/34 set up for a 20mA connection. If anyone would like a VT52 or the VT61, let me know. I have a minimal amount of money in these ($30 to $50 each) and would be willing to sell them for that price. I've been watching eBay for 6 months and have only seen one of these types of terminals on there. For those of you who aren't familiar with them, they were commonly used on DEC systems (PDP-8 and PDP-11) back in the mid-1970s and later. I have two or three VT52s and the VT61 that I'm wanting to get rid of. The VT61 seems to be quite uncommon. I can't find much about it on Google. It had more features than the VT52 and I think did "full screen" processing, but I'm not sure. Ashley

This is not really in response to your question, but at least on-topic. In the late '80s, I shared an office with 3 other grad students. One had a Mac SE/30 and was ahead of the rest of us in learning the internet. He got the serial line connection to the building Unix box run into our office, discovered how to ftp files >from internet sites, D/L over serial to the macs, decompress, etc. One night around midnight (when the rest of us were asleep), he discovered a site with a bunch of sound clips from movies, and software to substitute the clips for system beep, startup chime, etc. He went to work, and got his box all set up the way he wanted. Next morning, I came in long before he was up, and fired up his machine to do something on it. Instead of <Beeeeep!> it said "My GOD! It's full of *STARS*! <opening strains of Also Sprach Zarathustra>". Oh, verrry nice. I explored the new directory, discovering eventually clips from "Alien" among quite a few others. I *also* discovered the graphical sound-clip editor that came with the package. Hmmm. I set to work. An hour or so later, the owner of the machine walked in, a bit bleary-eyed but looking smugger than anyone I have ever seen before or since. "Hey, guys", he chirped, "I found some new software. Wait'll you see!" Sitting down at his desk, he gave us all another smug look, flipped the switch and leaned back in his chair as the disk spun up. "What?" we said, our best innocent looks plastered across our faces, "a new startup screen or something?" "You'll see..." came the response. The computer finally piped up, "My GOD! It's full of <click> *..SH1T..* <click> <opening strains of Also Sprach Zarathustra>". It turns out Sigourney Weaver's voice (as in Alien), if frequency-shifted down about half an octave, is almost a dead ringer for Keir Dullea's (as in 2001). Mr. Smug's head snapped around in the fastest double-take I've ever seen. "WHAT!" Then realization set in.. "You guys...." He cleaned up the <click>s and kept the startup sound for months, though. -- - Mark 210-522-6025, page 888-733-0967

Early timesharing/BBS systems

by rcini＠optonline.net

Hello, all: I was at VCFe yesterday and I have to say that the speakers and demonstrations were great. Sellam did a fantastic job and where the event was located at the Sun facilities worked out perfectly. One demo that I missed was the ARPANET dial-up simulation which wasn't there when I left at 3:30. Anyway, this demo brings-up an interesting question. What kind of dial-up systems existed in the 70's before consumer-oriented services like CompuServe? I remember the DowJones and CompuServe sign-up packs at RadioShack in maybe 1979 (I joined CIS in 1988. I even remember my ID: 70153,3367). I also remember in high school (around 1983) using a DECwriter to dial into the timesharing computer (at 300 baud; I don't know the host system) at one of the local universities. Just curious. Thanks.

What is the foulest thing you have ever made a digitalker chipsetsay?!

by dwight.elvey＠amd.com

Hi When I was at Intel, years ago, Litrtronix just came out with one of those four letter LED display modules. At the time, I had a 8741 in my desk drawer. I decided to make a random four letter word display. Between me and another fellow, we had about 15 or so good ones. Then we got help from this lady that worked as a tech writer.

OSI 560Z: DEC PDP-8 clone using 6100 & 6502

by dfnr2＠yahoo.com

Hello, Having recently acquired some 6100's (I know they're lesser than the 6120), I thought I'd try a PDP-8 project (I remember seeing these, but never got to play with one.) Ohio Scientific had a board--the 560Z--which contained a 6100, a 6502, and a Z-80. The 6502 was "microprogrammed" to emulate the PDP-8 IOT codes, and OSI claimed that it was fully compatible. Has anyone played with one of these suckers? How good was the emulation? Does anyone have any info on the schematics of that board, or the 6502 firmware? Or, does anyone have an unused 560Z, working or not, they'd be willing to part with? I'm also aware of the SBC6120; I plan to order one of these soon. Thanks, Dave __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security. So do we. http://promotions.yahoo.com/new_mail

MI Property Depot Report

by jbmcb＠hotmail.com

Went to the U of M property disposition the other day, they had an SGI POWER series rackmount server (4G3XX something) for $1000, and an IBM S/390 Paralell Generation 4 mainframe with transaction processors (two racks of them) for $1500. I'd pick it up in a heartbeat if I had any way of lugging the beast back to Detroit. They also had a few Sparc 20's for $25, some Sony video editing equipment, a ton of DLT and CD-ROM autoloaders for fairly cheap, and a bunch of those Sparc IPX sized Sun hard drive cases for $10 (With HD's) I picked up a handful of PCI audio/SCSI/ethernet cards for $2 each, a Sony WebTV, and a couple of Cisco EISA FDDI cards to expand my tangled nest of network standards run through my home. Cheers! _________________________________________________________________ Planning a family vacation? Check out the MSN Family Travel guide! http://dollar.msn.com

DARPA Grand Challenge Conference

by marvin＠rain.org

Anyone else going to the DARPA Grand Challenge Conference on Saturday, August 14th? Aside from the fact that a number of lightweights (including CMU Robotics) entered last year and are presumed to enter again this year, I think it would be totally cool to have a robotic vehicle powered by classic computers :)! A ton of information if you use Google, but the main site is: http://www.grandchallenge.org/ p.s. - The site doesn't work with Netscape 4.73 but works fine with (ugh) IE.

Computer history -- visiting the UK

by wmaddox＠pacbell.net

I will be leaving at the end of the week for a couple of weeks in the UK, mostly London and surroundings, but with a few days planned in Manchester and York. I am planning to visit Bletchley Park and the Babbage exhibit at the London Science Museum. I have heard that the Manchester Baby replica at the Manchester Museum of Science and Industry is run weekly (or was at one time). I couldn't find any mention of it on the museum's website. Does anyone know the current status and schedule? Any pointers to other exhibits or locations that are a must-see? --Bill

Processor Technology Software Wanted

by Watzman＠neo.rr.com

Does anybody, by any chance, have a copy of the processor technology "Simu-cisor" program? It is a program for testing a Persci drive that exactly simulated the Persci factory drive exerciser hardware using a PT Helios disk controller. It was distributed on audio cassette tape, not disk, and it's tape name was "SIMU". It was only a dealer/service center item, it was not normally distributed to end-users. If you have this, please contact me (Watzman(a)neo.rr.com). Thanks, Barry Watzman

Unisys System 80 pictures available

by aek＠spies.com

In the upcoming days, I'll be able to send you a description of the hardware -- Is there any documentation with the system? The System 80 was the last descendent of the Univac 9000 series, a 360-ish 32 bit architecture. I had a little exposure to a 9300, which was very much like a 360 with the exception of I/O I'm sure all of this evolved as did the 360 to 370 over 20+ years.

Hi all ! Several of you were interested in pictures of the Unisys Mainframe. In the upcoming days, I'll be able to send you a description of the hardware (I don't have access to the descriptions at the moment). It would be nice, if somebody could put these pics online in a computer museum or so 'cause I haven't seen pictures of the System 80 on the internet so far.

Help on Morrow Decision I - docs or direct experience?

by r.stek＠snet.net

My last S-100 I purchsaed before caving in to an IBM clone was the Morrow Decision I. I loved its ability to handle N* hard-sectored as well as soft-sectored 5" disks as well as 8" drives, and of course a huge 15 MB hard drive I had salvaged from my Horizon. Alas I sold it before moving back to the US from Canada. I now have a Decision I (with a more industrial metal case, locking key-switch plus built-in Fujitsu hard drive and more "sophisticated" MB) and Allison Parent was kind enough to get the switching PS going again for me, and I finally tried hooking it up to a Televideo terminal. There are 4 ports on the "MB" - 3 standard 25 pin D-connectors and 1 15 pin, all coming off the back of the MB. Upon booting, it sounds like the HD is loading, but I get no response, not even garbage, from any of the 3 25 pin connectors. (And I don't have a 15 pin connector right now to make an adapter, so chances are that the 15 pin connector is the 'master' serial port while the other three are for the multi-user Micronix which apparently this Decision I was set up for (I also found some hand-written labels on one of the boards referencing "M*nix") or are parallel ports. Anyway, this is not the Decision I that I had some familiarity with. Is there anyone out there who knows this machine who could help me get it up and running again? I have the docs for the Z80 CPU, the Disc Jockey DMA controller, the hard drive controller and the 256k memory card, but not for the 'advanced' MB (I don't know enough circuitry to figure out what the heck all the extra stuff is - obviously some serial ports or maybe a combination of serial and parallel). I don't even know at this point if this unit can be made to run plain vanilla CP/M (or preferably ZCPR) (I found some web references to Micronix having to "transfer" files from a CP/M disk over to Micronix before they could be used.) I don't even know if there are any specific "features" which would prevent me from running CP/M on this unit. I also have some Morrow 5" and 8" diskettes with CP/M and CBIOS files for various combinations of 5" and 8" configuartions off the the DJ DMA board. At this point ANYTHING anyone can tell me about the Micronix Decision I would be helpful. Thanks. Bob Stek Saver of Lost Sols (...and other stuff)

RK05 stuff

by GOOI＠oce.nl

Ashley, perhaps "kicking an open door", but you know that the 4 cards of the RK11 go in a *dedicated* 4-slot backplane? *not* in 4 SPC slots of the 11/34 backplane. For more info on the PDP-11/34, check my website www.pdp-11.nl and click the 11/34 link. There is also some stuff about the floating point processor and the cache module, including the power distribution when you want to install both options.

Yes, it has a total of 12 jumpers. All the ones that are "in" for Unibus should be "out" for Qbus, and vice-versa.

Why does my KDF11 cause spurious traps to 4??

by bob＠jfcl.com

Hello, I've got a 11/23+ in a BA23 and when running RT11 I get spurious and unexpected traps to 4. After while I noticed that it will do the same thing while running the extended memory test built into the boot ROMs. I pulled out all the cards except the CPU and the memory and it still does it, and after swapping memory with another QBUS system that's known to work I've pretty much come to the conclusion that it's not the memory. Bummer - looks like the KDF11 is at fault. I actually cobbled the system together myself from an assortment of cards and parts, so it's not unlikely that I did something wrong. Is there any obvious mistake or mis-setting of the KDF11 jumpers that would cause this, or is my CPU card hosed? Thanks, Bob Armstrong

VCF East 2.0 wrap-up: Computer Collector E-mail Newsletter

by evan947＠yahoo.com

Hello fellow collectors, VCF East 2.0 was terrific, and I'm sure Sellam Ismail will comment on it soon, when he's recovered from the long flight home! Meanwhile, below is my own view of the show, as printed in this week's issue of the Computer Collector E-mail Newsletter (http://news.computercollector.com -- it's FREE to subscribe.) ==================================================== BURLINGTON, MASSACHUSETTS, Sun Microsystems -- This week, I'm happy to report that VCF East 2.0 was a success. Everyone learned something, or bought something, or just enjoyed reminiscing. Personally, I experienced all three, and took home a second-place award in the "other" category for my exhibit, "PDAs: 1973-1993". (Compared to all the minis and micros, my PDAs and heldhelds fell into the "other" category. Hopefully in the future there will be enough people who collect luggables, notebooks, handhelds, and transputers to make "portables" a full category of its own.) Here are some of the event highlights, from my point of view. - Friday morning set-up. A great thing about VCF events is that everyone helps with the venue set-up. Getting vintage computers to work, especially for people who traveled a long distance to attend, can be challenging. Luckily, there's no better place than a VCF floor to find knowledgeable people who can help you. From schlepping to sharing power cords to configuring boot-up sequences, there was something for everyone to do. Unlike during the public exhibition hours when you end up showing the same functions of your computers over and over, during the set-up period you can really get your hands dirty and learn something, and that certainly was the case this time. At one point we all learned that the power outlets in our portion of the Sun building shared just TWO circuits. Thankfully nobody killed the power for eastern Massachusetts. (Everyone setting up Friday morning also is indebted to Sun for letting us take over their building and parking lot, and especially to public relations staffer Samantha Moulton, who served as the event liaison. Sam: THANK YOU!) - Also Friday morning, many exhibitors took a break from set-up and joined the attendees at the speaking sessions. My own exhibit set-up is relatively simple, so I went to the first two sessions - Curt Vendel and Steve Golson's Atari "7800 20th Anniversary" talk, and event owner/newsletter writer Sellam Ismail's "VCF Ramblings" talk. In the Atari talk I learned the reality vs. the legend of how Atari's executives ran the company, how that affected customers, and how companies like Coleco and Nintendo exploited Atari's mistakes. The talk also gave me some new respect for the technical brilliance of the 7800 and its developers. Next, in Sellam's talk, I learned the details of his PDP-8 replica for Tokyo's National Science Museum. The replica worked by running Bob Supnik's simulator software on a Linux computer behind a "blinkenlights" front panel, with the computer case itself made from wood. Besides the case, I was amazed to learn how many of the replica's switches and other electromechanical parts came not from a computer parts bin, but from Sellam's local hardware store! Now that the PDP-8 and other replicas are built, Sellam says he'll build one for anybody. More information will come in the future. Unfortunately I missed Bob Supnik's own talk, and that of Sun's panel on the history of storage networks. The good news is that all of the panels were recorded, so hopefully they will be available soon for public viewing. We'll let you know the details as soon as possible. - The influx of Sun employees -- almost 1,000 work at the Burlington facility -- into Friday's public exhibits was terrific. At my own exhibit, I really enjoyed that so many of them appreciated my handhelds collection and asked smart questions. Looking over the 20 or so devices that I brought along, many commented that they owned this or that device back when it was new. But even among them, most were suprised to learn some of the virtually unknown PDA functions and options that existed in the mid-to-late 1970s and early 1980s. That's definitely inspiration for me to keep collecting and researching. - Vince Briel's Replica 1. Vince, congratulations on winning the "Best of Show" award! Vince's exhibit area was right next to mine, so during the rare slow times, I talked to him about his project. My soldering skills are shaky, but I'm strongly considering attemting the Apple 1 replica build. Vince generously took the time to explain every step to me, in terms I could understand. If I do attempt the project, then I'll record every detail here in the newsletter. The moral? If I can do it, anyone can, trust me! Vince also impressed everyone with his industrial design skills, as the Replica 1 he brought along has a case made of see-through plexiglass, with a hinged top cover. As cool as an Apple 1 replica is, this made it even nicer. - Friday night's VCF party. At the day's end, almost all of the exhibitors and their guests -- about 25 people -- went to dinner together at a local steakhouse, with the outside modeled to look like railroad cars. Beer, many laughs, and the meat all came in large quantities. Of course vintage computer collectors come in all shapes and sizes -- and boy, can some of them eat! I'll refrain from naming the guilty, you know who you are. :) - Saturday's talks and exhibit. We all dragged ourselves out of bed Saturday morning and, once again, encroached on Sun. The highlight from Saturday was Art Hill's talk, "A Personal History of Computing," during which the 82-year-old Hill (who has more energy than me, at 29!) wowed everyone with his stories. To me the most exciting part was that Hill actually worked with and learned from J. Presper Eckert and John W. Mauchly, the builders of ENIAC. He also worked with the famous Navy Adm. Grace Hopper, who was largely responsible for COBOL, the "common business-oriented language," who but did not (despite the myth) coin the term "bug" in reference to computing. Some of Art's stories were wilder than others,but as he admits, age has a way of muddying the details. I missed the next talk on the IBM/360 by Lawrence Wilkinson, as I had to prepare for my own talk that afternoon, and I missed the final talk, from John Titus who developed the Mark-8 hobbyist kit. (I'd like to think my own talk on the history of PDAs was a show "highlight" for others! A good sign came through the www.classiccmp.org mailing list last night, as an attendee mentioned on the list that "There is actually an HP41 calculator here," referring to my own exhibit. So it's not just computer collectors that come in all shapes and sizes -- it's the computers too.) Overall, Saturday's attendence at the exhibits was a little slower than Friday's, but it gave the exhibitors themselves a chance to check out each other's work. I brought home many good memories and a few new toys from VCF East. After dinner Friday night, I helped classiccmp.org administrator Jay West and others swap some DEC and other gear between minivans and trailers in the Marriott parking lot -- we sure hope Jay made it home safely to Kansas City, after his flat-tire adventures during the inbound trip on I-84 in Connecticut. It was also great to see newsletter founder Mike Nadeau sell many copies of his book, "Collectible Microcomputers." I experienced a really funny moment as well: at one point Friday, Sellam walked over to my exhibit and, not joking, asked "Got a calculator?" Given the nature of vintage PDAs, I had about 15 calculators! Finding one that was JUST a simple calculator and had fresh batteries was the challenge, but we eventually did. Many of us went to dinner again on Saturday night, and once again I was wowed by the computing stories (and appetites!) of my fellow hobbyists. As for toys, I acquired a TRS-80 Model 100, and a DVD copy of Steve Wozniak's speech from last year's K-Fest event. (Many VCF attendees will be at the Apple II event this week, including VCF Europa leader Hans Franke and Commodore 64 heroine Jeri Ellsworth. See www.kfest.org for more information.) ==================================================== See you all at VCF 7 -- just THREE MONTHS away! - Evan Koblentz

Atari TT030 (or ST?) joystick?

by Arno_1983＠gmx.de

Since I've got the User's Manual (and the machine, which I got with a crashed HDD) kicking around... Translated: Chapter 1 - Getting Started: "Most computer games rely on joysticks as input devices. Exactly how the joystick is used depends much on the game itself. Remark: Joysticks are not included. Warning: Broken joysticks can prevent the TT from initializing correctly. If you encounter any problems, you should switch off the computer, remove the joystick(s) and turn the TT on again. Connecting Joysticks Joysticks use the same connector as the Atari Mouse and can be plugged in on either side of the keyboard." Appendix F- Pinouts: "Mouse/Joystick 0 (DE9 male) 1 - XB/Up 2 - XA/Down 3 - YA/Left 4 - YB/Right 5 - middle Button 6 - left Button/Fire Button 7 - +5V 8 - Ground 9 - right Button/Fire Button Joystick 1 (DE9 male) 1 - Up 2 - Down 3 - Left 4 - Right 5 - reserved 6 - Fire Button 7 - +5V 8 - Ground 9 - unused" Hope that helps...

Help with Apple2 clone "Orange Peel"

Hi Tony, >> So - I have a bit of a paradox : the "2kb/2716" label suggests >> ROM's, and the 64k of RAM on the mainboard also indicates that >> all the RAM is on the lower board, however the ROM strings >> suggest that this may be the only ROM. > >IIRC, a real Apple ][ has up to 64K RAM (48K on the mainboard, 16K on a >language card) and some ROMs. The ROMs are bank-switched with the top 16K >(Language card) RAM. That's correct. There are also two language cards, one just has 16k to replace the ROM's, and one has more memory which can be bank switched into the 16k ROM address space. >It sounds like you effectively have a built-in language card (that would >be quite sensible), and you have RAM in place of the ROM (possibly to get >round Apple copyrights). The 5517 RAMs take the place of ROMs -- they're >loaded once on boot-up, and then contain the resident BASIC, etc. The >EPROM you have sounds like a bootloader for these RAMs. Thats exactly what I am thinking. Still trying to figure it out - never gets as far as trying to read the disk - does chip select the ROM and appear to read some code from it, but does not make it much further. Btw, do you (or anyone) have the pinout for 4564 DRAM's? I'm wondering if they are in backwards (as noted previously, someone "worked" on this unit) - 16 pins, showing +5 on pin 8 and Gnd on pin 16 - backward to most chips, although I do recall there were some memory chips with odd power... Lack of working main RAM would explain it's behavour.

All you need to do is take 4 lengths of wire-wrap wire (or something similar) and join together all the pins that connect to the BC1 fingers, all the BD1, all the BE1, and all the BF1. If you can view (or print) PostScript files there's a diagram showing the finger layout at http://www.dunnington.u-net.com/public/PDP-11/ QBusConns.ps is actual size, QBusConnsBig.ps is somewhat larger. I expect there are text lists of the signals/fingers around the web too. If you plan to use a processor with PMI memory you might also want to link AF1 on the first (top) slot to AF1 on the slot (or two slots) immediately below. That's the SRUN connection; without it the RUN LED won't light. -- Pete Peter Turnbull Network Manager University of York

Connecting a FPF11 to a 11/23+ (Dumb Questions)

by bob＠jfcl.com

I just got my hands on an FPF11 board, and naturally I want to connect it to my 11/23+ right away! I understand that the 40 pin header on the card edge connects to a 40 pin DIP plug that goes into one of the microcode option sockets on the 11/23+. Dumb question #1 - is it conventional to install the FPF11 in the slot immediately below the CPU, thus displacing all the memory boards down a slot? Or does the FPF11 go in the first Q/Q slot (slot 4) ? Or does it even matter? Dumb question #2 - the handbook says, "[the FPF11] ... complements the KEF11-AA". Does this mean that the FIS option chip must _also_ be installed in the 11/23+? Or must it _not_ be installed? Dumb question #3 - does it matter which one of the microcode option sockets you plug the FPF11 into? And... #4 - how do you know if the thing's working? Short of having the diagnostics for it, of course, which I don't. Thanks, Bob Armstrong

Help with Apple2 clone "Orange Peel"

by dave04a＠dunfield.com

Hi, I am trying to resurrect a dead Apple2 clone for a friend. This machine is called "Orange Peel", and is packaged as a small rectangular box with three slots accessable on one end by sliding back the top, and a separate keyboard. I believe the machine is running, at least it clears video memory to zero (familier '@' pattern) on powerup, but goes no further - the ROM/RAM configuration seems odd: The main board contains 8 4564 DRAM's along with video and I/O circuitry etc. The CPU lives on a separate board which is suspended above the mainboard on long, hard-to-insert pins. The CPU board has 7 sockets. At one end is a single 2716 EPROM chip labled "New boot", near the other end of the line is a label on the board which reads "2kb/2716" - this suggests that the whole line should be ROM's (which would be consistant with other apples), however the remaining sockets contain 5517 CMOS RAM's !!! - clearly there is no other code on this board. Inside the "New Boot" ROM, the only strings I can see are: FBPASIC OR INTBASIC FILE REQUIRED INSERT APPLICATION DISC AND PRESS ESC This suggests that it loads basic from disk and would not have it in ROM. So - I have a bit of a paradox : the "2kb/2716" label suggests ROM's, and the 64k of RAM on the mainboard also indicates that all the RAM is on the lower board, however the ROM strings suggest that this may be the only ROM. Perhaps it loads code from the disk into "Pseudo-ROM" 5517 bank? (If so, anyone got the disk code)? The fact that several of the riser pins were not inserted and bent under the CPU board indicates that someone with low skills "worked" on this system at one point. The fact that the attached power cord was cut off indicates that it was given up on ... so I cannot assume that it is configured correctly. Is anyone familier with this system? Can anyone tell me if the CPU board accepts RAM or if it should be ROM? If so, does anyone have the proper code? If it loads the RAM's from disk, does anyone have the disk?

Atari TT030 (or ST?) joystick?

by julesrichardsonuk＠yahoo.co.uk

Hi all, Anyone know if I can use a joystick on the Atari TT030? If so, what type, which port does it use etc. (and does anyone have the relevant port pinouts so I can wire up an adapter? I don't have an Atari-specific joystick, but I do have ones from various other machines kicking around) Given the ST compatibility, I assume it can be done... cheers Jules

Early timesharing/BBS systems

by aek＠spies.com

This is an area I'm working on in trying to bring some of these systems back to life through simulation. MIT had a timeharing PDP-1 system, as well as CTSS on a modified 7090 in the early 60's. BBN also had timesharing on a PDP-1. CTSS's replacement was Multics. UC Berkeley modified an SDS 930 to add memory protection and developed the GENIE timesharing system in the mid 60's. SDS sold the 940, as the modified 930 was called with modified versions of the GENIE software. The most well known 940 systems were at SRI (which eventually was sold to the folks who did the Community Memory Project), BBN, and Tymshare. Tymshare migrated from their 940s to DEC10's in the 70's. The people who did the 940 at UCB started Berkeley Computer Corporation and produced one prototype of their BCC500 system, which was moved to the University of Hawaii after BCC folded, and many of the people formed the core of the computer group at PARC. Dartmouth produced their BASIC timesharing system in the mid 60's, about the same time as GENIE. IBM produced TSS-360, the less said about that, the better.. DEC timesharing monitors for the PDP-6 evolved into the timesharing monitor on the PDP-10, which later became TOPS-10. BBN's TENEX operating system for the PDP-10 later became TOPS-20. Smallish timesharing systems were also produced which included TSS/8 for the PDP-8, which was inspired by a phd thesis Gordon Bell supervised at CMU, which sort of evolved into RSTS (originally called EDUSYSTEM 100) and RSTS/E.

Monitor deflection magnets; what to do when one falls out & breaks?

by brad＠heeltoe.com

Hi, I have an old B&W "specialty" monitor which recently stopped working. In the process of moving it around (to/from repair place) I noticed a little black "tube magnet" dropping out when I took the cover off. At the time I didn't think much of it (those in the know can chuckle now). So, after a bout of replacing bad caps with no luck, I eventually broke down and replaced the deflection board and the monitor sprang to life. Much joy. (note: "specialty" = designed for a specific computer with a special ECL video connection and has no standard connector or interface. and no schematics) So, monitor is working. I proceed to adjust the H & V size, linearity, etc... I notice that the bottom and sides will square up nicely but the top edge has a large "dip" in the middle. No amount of trimmer fiddling will fix this. light goes off. "found" tube magnet is part of yoke assembly. So, I notice where the missing magnet came from. Naturally it's on the top side of the yoke assembly. But - the "tube" has broken into 3 pieces (it was broke when I found it. honest). I carefully glued it back together (no glue in the joints, however) and replaced it. This helped a little but did not cure the problem. [note to reader: I never took that fields course. I know nothing of magnets.] So, - is a broken magnet pushed back together not as good as a whole magnet? (strength wise) - can I get a new magnet somewhere? - is there anything special about these magnets? - do normal monitor repair guys just have a box of these laying around? - does this sort of thing happen all the time? -brad

I've not tried to boot a VAXstation 4000 from CD-ROM, but I've had no problem with lots of other classic machines using older Toshiba drives. Almost all modern (newer than about mid-90s) drives understand the SCSI command to set the blocksize to 512 bytes in software, but older machines don't know to do that. I keep a couple of Toshibas just for that reason; XM3201, XM3301 and XM3401 at least have a couple of pairs of half-moon solder pads, near the SCSI connector, normally linked for 2048-byte blocks, but you can cut the tracks between one or both to set 512-byte blocks. The three different 512-byte settings are supposed to be for Sun, SGI, and Intergraph, but I've never noticed much difference. OTOH, I have a couple of Hitachis and an NEC which can be set to 512-byte blocks, and they don't work too well (the Hitachis in particular are very slow and generate lots of errors), so apparently not all CD-ROM drives are created equal. -- Pete Peter Turnbull Network Manager University of York

simh and rt11 primer.

by eric＠redrouteone.net

Hello, I have wanted a PDP11 for years but currently do not have the space for one so I have decided to do the next best thing use simh. I have downloaded simh and the rt11 disk image but I am kind of stuck on where to go. Does anyone know of any sites or documents available online that cover configuration of simh and the installation and use of rt11. I have done some messing around and have managed to boot the rt11 image by using the commands at rl0 rtv53_rl.dsk at rl1 eric_pdp11_rt11.dsk <- This is a file that I intend to do my install to. Is that wrong? Boot rl1. I choose the automatic option but then it wants me to mount a disk in dl1 so that it can backup the media. I try to attach dl1 but I get an error non existent device. If try to create the disk during the install the install just errors out and dies. Any help with this will be most appreciated. Eric

Monitor deflection magnets; what to do when one falls out & breaks?

by dwight.elvey＠amd.com

Hi It should be noted that when broken, these cheap magnets will lose some of their magnetism that can not be recovered by simply gluing the piece together. As was mentioned, finding others on scrap units is the easiest. Positioning these is an art. They never seem to do what one expects so take your time at locating the best location and orientation. It most likely will not be the same as it was originally. Watch out for the anode lead and wear eye protection, any time you are working on he monitor with the cover off.

Monitor deflection magnets; what to do when one falls out & breaks?

by melamy＠earthlink.net

these are indeed magnets and were usually the dirt cheap variety. They were set in place at the factory to "trim" the beam to overcome mechanical deviations in the gun and deflection assemblies internal to the crt. They were not all that powerful. The best source of replacement would be another old monitor that you can take the magnets out of. best regards, Steve Thatcher -----Original Message----- From: Brad Parker <brad(a)heeltoe.com> Sent: Jul 15, 2004 11:54 AM To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk(a)classiccmp.org> Subject: Re: Monitor deflection magnets; what to do when one falls out & breaks?

(I would think a ferrite core would have wires wrapped around it) These magnets are not connected to the wired internal yoke assembly - they are glued to a "collar" which is close to the back of the tube. The collar is round but the magnets are glued to make a square - I assume this helps make the image square. (or not :-) The magnets on the two sides are symmetric as are the top and bottom. Both top and sides have two "tube magnets" but ared spaced slightly differently. The sides have two magnets side by side with no gap. The top and bottom have two magnets side by side with a a 1/4" gap. I can see where the glue was holding the magnet. That's where I put it back. I assume the poles should be aligned, i.e. the poles of the two magnets should be the same, producing a larger overall field (I presume) >As for the problem, I wonder if the issue is that the core is in the >wrong spot.

East German arcade game

by transit＠lerctr.org

http://www.bbc.co.uk/wiltshire/features/polyplay.shtml The Poly Play videogame was Eastern Bloc's answer to the capitalist's Pac Man but resembles something more like on old-fashioned TV set in a tall wooden cabinet. Nevertheless, with up to eight games, a simple firing button and 8-way joystick, and a slot to take tokens rather than coins, the Poly Play is, in fact, less grim than it sounds. Simon Webb, the curator of Swindon's Museum of Computing told BBC Wiltshire, "The story goes that this was the only arcade approved machine to be produced in East Germany and they used to go into places like municipal swimming pool and leisure centres. "When the Berlin Wall came down, for some strange reason they recalled the machines to the factory and had them dismantled. A few were salvaged. There were probably about 1000-1500 made."

VCF and lisp machines

by brad＠heeltoe.com

Hi All If anyone going to VCF and is interested in Symbolics workstations or any type of Lisp Machine (like CADR's), and would like to get together and talk about them, let me know (via email). I should probably have put together a talk about my explorations tracking down old lispm's and emulating lisp machine microcode - maybe for next year. I'll certainly be there, floating around looking for (more) unibus hardware and I'll be at the Atari 7800 talk. -brad Brad Parker

Booting a VAXstation 4000 VLC off the hobbyist boot CD-ROM

by dbetz＠xlisper.mv.com

I have my VAXstation 4000 VLC running to the ">>>" prompt and would like to boot the hobbyist CD-ROM to install VMS on the hard drive but I'm having trouble getting the CD-ROM to boot. If I type 'boot dka400' at the prompt, the CD-ROM spins up and I get the text "-DKA400" displayed on the console but then I get the ">>>" prompt again. Can anyone tell me why that would happen? I'm using a NEC CDR-1910A SCSI CD-ROM drive set to SCSI ID 4.

OT dsl

by dan_williams＠ntlworld.com

I have been looking at bulldogdsl they have a 4 meg line with 400k up for 30 pounds a month. Has anyone hear used this or know anyone that does. I was wondering about reliability this is less then I pay ntl for a 1mb line. They also have 8 fixed ip's for an extra 9 a month. It seems too cheap to me. Thanks Dan
